Querying Very Large Multi-dimensional Datasets in ADR-Extended AbstractTahsin Kurc,Chialin Chang,Renato Ferreira,Alan Sussman,Joel Saltz Institute for AdvancedComputer StudiesandDept.of Computer Science University of Maryland College Park,MD20742Dept.of Pathology Johns Hopkins MedicalInstitutions Baltimore,MD21287kurc,chialin,renato,als,saltz@1IntroductionAnalysis and processing of very large multi-dimensional scientific datasets(i.e.where data items are associated with points in a multi-dimensional attribute space)is an important component of science andengineering.Moreover,an increasing number of applications make use of very large multi-dimensional datasets.Examples of such datasets include raw and processed sensor data from satellites[12],output fromhydrodynamics and chemical transport simulations[10],and archives of medical images[1].Many applications that make use of multi-dimensional datasets have several important characteristics. Both the input and the output are often disk-resident datasets.Applications may use only a subset of all thedata available in input and output datasets.Access to data items is described by a range query,namely a multi-dimensionalbounding box in the underlying multi-dimensionalattribute space of the dataset.Only thedata items whose associated coordinates fall within the multi-dimensional box are retrieved.The processing structures of these applications also share common characteristics.Figure1shows high-level pseudo-codefor the basic processing loop in these applications.The processing steps consist of retrieving input and output data items that intersect the range query(steps1–2and4–5),mapping the coordinates of the retrievedinput items to the corresponding output items(step6),and aggregating,in some way,all the retrieved input items mapped to the same output data items(steps7–8).Correctness of the output usually does not dependon the order input data items are aggregated.The mapping function,,maps an input item to a set of output items.An intermediate data structure,referred to as an accumulator,is used to hold intermediate results during processing.For example,an accumulator can be used to keep a running sum for an averagingoperation.The aggregation function,,aggregates the value of an input item with the intermediate result stored in the accumulator element().The output dataset from a query is usually much smaller than the input dataset,hence steps4–8are called the reduction phase of the processing.Accumulator elements are allocated and initialized(step3)before the reduction phase.Another constraint is that there isOutput Dataset,Input Dataset(*Initialization*)1.foreach in do2.read3.(*Reduction*)4.foreach in do5.read6.7.foreach in

the accumulator are post-processed to producefinal results(steps9–11).Typical examples of application classes that make use of multi-dimensional scientific datasets are satellite data processing applications[15,5],the Virtual Microscope and analysis of microscopy data[1], and simulation systems for water contamination studies[10].Due to limited space,we briefly describe the satellite data processing application here.In satellite data processing,earth scientists study the earth by processing remotely-sensed data continuously acquired from satellite-based sensors.Each sensor reading is associated with a position(longitude and latitude)and the time the reading was recorded.In a typical analysis[15],a range query defines a bounding box that covers a part or all of the surface of the earth over a period of time.Data items retrieved from one or more datasets are processed to generate one or more composite images of the area under study.Generating a composite image requires projection of the selected area of the earth onto a two-dimensional grid[18];each pixel in the composite image is computed by selecting the“best”sensor value that maps to the associated grid posite images can be added to the database as new datasets.We have developed an infrastructure,called the Active Data Repository(ADR)[3],that integrates stor-age,retrieval and processing of large multi-dimensional datasets on distributed memory parallel architectures with multiple disks attached to each node.ADR targets applications with the processing structure shown in Figure1.ADR is designed as a set of modular services implemented in C++.Through use of these services, ADR allows customization for application specific processing(i.e.the,,,and functions),while providing support for common operations such as memory management,data retrieval,and scheduling of processing across a parallel machine.The system architecture of ADR consists of a front-end and a parallel back-end.The front-end interacts with clients,and forwards range queries with references to user-defined processing functions to the parallel back-end.During query execution,back-end nodes retrieve input data and perform user-defined operations over the data items retrieved to generate the output products.Output products can be returned from the back-end nodes to the requesting client,or stored in ADR.Several runtime support libraries andfile systems have been developed to support efficient I/O in a parallel environment[2,6,8,9,13,14,16,17].ADR differs from these systems in several ways.First, ADR is able to carry out range queries directed at irregular spatially indexed datasets.Second,computation is an integral part of the ADR framework.With the collective I/O interfaces provided by many parallel I/O systems,data processing usually cannot begin until the entire collective I/O operation completes.Third, data placement algorithms optimized for range queries are integrated as part of the ADR framework.In this work,we discuss optimizing the execution of range queries(i.e.the processing loop shown in Figure1)on distributed memory parallel machines within the ADR framework.We describe three potential strategies for efficient execution of such queries.We evaluate scalability of these strategies for different application scenarios,varying both the number of processors and the input dataset size,using application emulators[19]to generate various application scenarios for the applications classes that motivated the design of ADR.We present experimental evaluation of the three strategies on a128-node IBM SP.2Query Execution in ADR2.1Storing Datasets in ADRA dataset is partitioned into a set of chunks to achieve high bandwidth data retrieval.A chunk consists of one or more data items,and is the unit of I/O and communication in ADR.That is,a chunk is always retrieved as a whole during query processing.As every data item is associated with a point in a multi-dimensional attribute space,every chunk is associated with a minimum bounding rectangle(MBR)that encompasses the coordinates(in the associated attribute space)of all the items in the chunk.Since data is accessed through range queries,it is desirable to have data items that are close to each other in the multi-dimensional space in the same chunk.Chunks are distributed across the disks attached to ADR back-end nodes using a declustering algorithm[7,11]to achieve I/O parallelism during query processing.Each chunk is assigned to a single disk,and is read and/or written during query processing only by the local processor to which the disk is attached.If a chunk is required for processing by one or more remote processors,it is sent to those processors by the local processor via interprocessor communication.After all data chunks are stored into the desired locations in the disk farm,an index(e.g.,an R-tree)is constructed using the MBRs of the chunks.The index is used by the back-end nodes tofind the local chunks with MBRs that intersect the range query.2.2Query PlanningA plan specifies how parts of thefinal output are computed and the order the input data chunks are retrieved for processing.Planning is carried out in two steps;tiling and workload partitioning.In the tiling step, if the output dataset is too large tofit entirely into the memory,it is partitioned into tiles.Each tile,, contains a distinct subset of the output chunks,so that the total size of the chunks in a tile is less than the amount of memory available for output data.Tiling of the output implicitly results in a tiling of the input dataset.Each input tile,,contains the input chunks that map to the output chunks in tile,.During query processing,each output tile is cached in main memory,and input chunks from the required input tiles are retrieved.Since a mapping function may map an input element to multiple output elements,an input chunk may appear in more than one input tile if the corresponding output chunks are assigned to different tiles. Hence,an input chunk may be retrieved multiple times during execution of the processing loop.Figure2 illustrates the processing loop with tiled input and output datasets.In the workload partitioning step,the workload associated with each tile(i.e.aggregation of items in input and accumulator chunks)is partitioned across processors.This is accomplished by assigning each(*Output and Input Dataset Tiles*)and for11.foreach in,do(*Initialization*)2.foreach in do3.read4.(*Reduction*)5.foreach in do6.read7.8.foreach in do9.(*Output*)10.foreach do11.12.writeFigure2:Basic processing loop with tiled input and output datasets.is the total number of tiles after tiling step.processor the responsibility for processing a subset of the input and/or accumulator chunks.2.3Query ExecutionThe processing of a query on a back-end processor progresses through four phases for each tile:1.Initialization.Accumulator chunks in the current tile are allocated space in memory and initialized.If an existing output dataset is required to initialize accumulator elements,an output chunk is retrieved by the processor that has the chunk on its local disk,and the chunk is forwarded to the processors that require it.2.Local Reduction.Input data chunks on the local disks of each back-end node are retrieved andaggregated into the accumulator chunks allocated in each processor’s memory in phase1.3.Global Combine.If necessary,results computed in each processor in phase2are combined acrossall processors to computefinal results for the accumulator chunks.4.Output Handling.Thefinal output chunks for the current tile are computed from the correspondingaccumulator chunks computed in phase3.If the query creates a new dataset,output chunks are declustered across the available disks,and each output chunk is written to the assigned disk.If the query updates an already existing dataset,the updated output chunks are written back to their original locations on the disks.A query iterates through these phases repeatedly until all tiles have been processed and the entire output dataset has been computed.Note that the reduction phase in Figure2is divided into two phases,localreduction and global combine.This is a result of workload partitioning for parallel query execution,as will be discussed in Section3.To reduce query execution time,ADR overlaps disk operations,network operations and processing as much as possible during query processing.Overlap is achieved by maintaining explicit queues for each kind of operation(data retrieval,message sends and receives,data processing)and switching between queued operations as required.Pending asynchronous I/O and communication operations in the operation queues are polled and,upon their completion,new asynchronous operations are initiated when more work is expected and memory buffer space is available.Data chunks are therefore retrieved and processed in a pipelined fashion.3Query Processing StrategiesIn this section we briefly describe three strategies that use different tiling and workload partitioning ap-proaches.More detailed descriptions of these strategies can be found in[4].We refer to an input/output data chunk stored on one of the disks attached to a processor as a local chunk on that processor.Otherwise, it is a remote chunk.A processor owns an input or output chunk if it is a local input or output chunk.A ghost chunk is a copy of an accumulator chunk allocated in the memory of a processor that does not own the corresponding output chunk.In the tiling phase of all the strategies described in this section,we use a Hilbert space-filling curve[7] to create the tiles.The goal is to minimize the total length of the boundaries of the tiles,by assigning chunks that are spatially close in the multi-dimensionalattribute space to the same tile,to reduce the number of input chunks crossing tile boundaries.The advantage of using Hilbert curves is that they have good clustering properties[11],since they preserve locality.In our implementation,the mid-point of the bounding box of each output chunk is used to generate a Hilbert curve index.The chunks are sorted with respect to this index,and selected in this order for tiling.The current implementation,however,does not explicitly take into account the mapping between the input and output chunks,and therefore in some cases there can still be many input chunks intersecting multiple tiles,despite a small boundary length.3.1Fully Replicated Accumulator(FRA)StrategyIn this scheme each processor performs processing associated with its local input chunks.The output chunks are partitioned into tiles,each of whichfits into the available local memory of a single back-end processor. When an output chunk is assigned to a tile,the corresponding accumulator chunk is put into the set of local accumulator chunks in the processor that owns the output chunk,and is assigned as a ghost chunk on all other processors.This scheme effectively replicates all of the accumulator chunks in a tile on each processor,and during the local reduction phase,each processor generates partial results for the accumulator chunks using only its local input chunks.Ghost chunks with partial results are then forwarded to the processors that own the corresponding output(accumulator)chunks during the global combine phase to produce the complete intermediate result,and eventually thefinal output product.3.2Sparsely Replicated Accumulator(SRA)StrategyThe FRA strategy replicates each accumulator chunk in every processor even if no input chunks will be aggregated into the accumulator chunks in some processors.This results in unnecessary initialization overhead in the initialization phase of query execution,and extra communication and computation in the global combine phase.The available memory in the system also is not efficiently employed,because ofunnecessary replication.Such replication may result in more tiles being created than necessary,which may cause a large number of input chunks to be retrieved from disk more than once.In SRA strategy,a ghost chunk is allocated only on processors owning at least one input chunk that projects to the corresponding accumulator chunk.The index,which contains the MBRs of all the chunks,is used to decide where ghost chunks need to be allocated.Note that the index is constructed when the dataset is loaded into ADR.3.3Distributed Accumulator(DA)StrategyIn this scheme,every processor is responsible for all processing associated with its local output chunks. Tiling is done by selecting from each processor its local output chunks until the memory space allocated for the corresponding accumulator chunks isfilled.As in the other schemes,output chunks are selected in Hilbert curve order.Since no accumulator chunks are replicated by the DA strategy,no ghost chunks are allocated.This allows DA to make more effective use of memory and produce fewer tiles than the other two schemes.As a result,fewer input chunks are likely to be retrieved for multiple tiles.Furthermore,DA avoids interprocessor communication for accumulator chunks during the initialization phase and for ghost chunks during the global combine phase,and also requires no computation in the global combine phase.The FRA and SRA strategies eliminate interprocessor communication for input chunks,by replicating all accumulator chunks.On the other hand,the distributed accumulator strategy introduces communication in the local reduction phase for input chunks;all the remote input chunks that map to the same output chunk must be forwarded to the processor that owns the output chunk.Since a projection function may map an input chunk to multiple output chunks,an input chunk may be forwarded to multiple processors.In addition,a good declustering strategy could cause almost all input chunks to be forwarded to other processors,because an input chunk and the output chunk(s)that it projects to are unlikely to be assigned to the same processor.4Experimental ResultsWe present an experimental evaluation of the three query execution strategies on a128-node IBM SP multicomputer.Each node of the SP is a thin node with256MB of memory;the nodes are connected via a High Performance Switch that provides110MB/sec peak communication bandwidth per node.Each node has one local disk with500MB of available scratch space.We allocated225MB of that space for the input dataset and25MB for the output dataset for these experiments.The AIXfilesystem on the SP nodes uses a main memoryfile cache,so we used the remaining250MB on the disk to clean thefile cache before each experiment to obtain more reliable performance results.We evaluate the query execution strategies for different application scenarios,varying the number of processors and the input dataset size.We used application emulators[19]to generate various application scenarios for the applications classes that motivated the design of ADR(see Section1).An application emulator provides a parameterized model of an application class;adjusting the parameter values makes it possible to generate different application scenarios within the application class and scale applications in a controlled way.The assignment of both input and output chunks to the disks was done using a Hilbert curve based declustering algorithm[7].Table1summarizes dataset sizes and application characteristics for three application classes;satellite data processing(SAT),analysis of microscopy data with the Virtual Microscope(VM),and water contam-ination studies(WCS).The output dataset size remainedfixed for all experiments.The column labeled Fan-in shows the average number of input chunks that map to each output chunk,while the Fan-out col-umn shows the average number of output chunks to which an input chunk maps for both the smallest andInput Dataset Computation Num.of Num.of Average(in milliseconds)

for the different phases of query execution(see Section2.3);I-LR-GC-OH represents the Initialization-Local Reduction-Global Combine-Output Handling phases.The computation times shown represent the relative computation cost of the different phases within and across the different applications.The LR value denotes the computation cost for each intersecting(input chunk,accumulator chunk)pair.Thus,an input chunk that maps to a larger number of accumulator chunks takes longer to process.In all of these applications the output datasets are regular arrays,hence each output dataset is divided into regular multi-dimensional rectangular regions.The distribution of the individual data items and the data chunks in the input dataset of SAT is irregular.This is because of the polar orbit of the satellite[12];the data chunks near the poles are more elongated on the surface of the earth than those near the equator and there are more overlapping chunks near poles.The input datasets for WCS and VM are regular dense arrays,which are partitioned into equal-sized rectangular chunks.We selected the values for the various parameters to represent typical scenarios for these application classes on the SP machine,based on our experience with the complete ADR applications.Figure3shows query execution times for the different applications.The graphs in the left column display the performance of the different strategies when the input dataset size isfixed,varying the number of processors.As is seen from thefigure,execution time decreases with increasing number of processors.The FRA and SRA strategies achieve better performance than the DA strategy on small numbers of processors for the SAT and WCS applications.However,the difference between DA and the other strategies decreases as the number of processors increases.This is because both communication volume and computation time per processor for DA decrease as the number of processors increases,whereas the overheads from the initialization and global combine phases for FRA and SRA remain almost constant.The graphs in the right column in Figure3display query execution time when the input dataset is scaled with the number of processors1.As is seen from thefigure,execution time increases for DA as the number of processors(and dataset size)increases,whereas it remains almost constant for the FRA and SRA strategies for the SAT and WCS applications.This is because the DA strategy has both higher communication volume and more load imbalance than the FRA and SRA strategies.For VM,we observed a largefluctuation in I/O times across processors,especially for large configurations,even though each processor reads the same amount of data. That is why overall execution time increases,although it should remain approximately the same.We would expect that the DA strategy should achieve better performance for VM,since the computation cost per block in VM is small,and it is a highly regular application with low fan-out of an input block to output blocks.Figures4(a)-(d)display the change in volume of communication and computation time per processor forfixed and scaled input datasets on varying number of processors1.Note that all strategies read the same amount of data from disks.However,the volume of communication for DA is proportional to the number of input chunks in each processor and the average fan-out of each input chunk,while for FRA it is proportional to the number of total output chunks.As is seen in Figure4(a),as the number of processors(a)SAT application.(b)WCSapplication.(c)VM application.Figure3:Query execution time for various applications withfixed input size(left),and scaled input size (right).increases,communication volume for DA decreases since there are fewer input chunks per processor,while communication volume remains almost constant for FRA.On the other hand,as seen in Figure4(b),the volume of communication for DA increases for scaled input size.The volume of communication for SRA implicitly depends on the average fan-in of each output chunk. If fan-in is much larger than the number of processors,it is likely that each processor will have input chunks that map to all output chunks.Thus,in such cases,SRA performance is identical to FRA.When the number of processors is greater than the fan-in,there will be fewer ghost chunks than there are output chunks for SRA,thus resulting in less overhead in the initialization and global combine phases than for FRA.This effect is observed for VM for32or more processors,and for WCS for64or more processors.As is seen in Figure4(c)-(d),the computation time does not scale perfectly.For DA this is because of load imbalance incurred during the local reduction phase,while for FRA and SRA it is due to constant overheads in the initialization and global reduction phases.The results show that all three strategies can be usefully employed for various applications under different machine configurations.We are working on cost models to automatically select the best strategy during query planning.References[1]A.Afework,M.D.Beynon,F.Bustamante,A.Demarzo,R.Ferreira,ler,M.Silberman,J.Saltz,A.Suss-man,and H.Tsang.Digital dynamic telepathology-the Virtual Microscope.In Proceedings of the1998AMIA Annual Fall Symposium.American Medical Informatics Association,Nov.1998.[2]R.Bennett,K.Bryant,A.Sussman,R.Das,and J.Saltz.Jovian:A framework for optimizing parallel I/O.InProceedings of the1994Scalable Parallel Libraries Conference,pages10–20.IEEE Computer Society Press, Oct.1994.[3]C.Chang,R.Ferreira,A.Sussman,and J.Saltz.Infrastructure for building parallel database systems for multi-dimensional data.In Proceedings of the Second Merged IPPS/SPDP(13th International Parallel Processing Symposium&10th Symposium on Parallel and Distributed Processing).IEEE Computer Society Press,Apr.1999.[4]C.Chang,T.Kurc,A.Sussman,and J.Saltz.Query planning for range queries with user-defined aggregationon multi-dimensional scientific datasets.Technical Report CS-TR-3996and UMIACS-TR-99-15,University of Maryland,Department of Computer Science and UMIACS,Feb.1999.[5]C.Chang,B.Moon,A.Acharya,C.Shock,A.Sussman,and J.Saltz.Titan:A high performance remote-sensingdatabase.In Proceedings of the1997International Conference on Data Engineering,pages375–384.IEEE Computer Society Press,Apr.1997.[6]P.F.Corbett and D.G.Feitelson.The V esta parallelfile system.ACM put.Syst.,14(3):225–264,Aug.1996.[7]C.Faloutsos and P.Bhagwat.Declustering using fractals.In Proceedings of the2nd International Conferenceon Parallel and Distributed Information Systems,pages18–25,Jan.1993.[8]J.Huber,C.L.Elford,D.A.Reed,A.A.Chien,and D.S.Blumenthal.PPFS:A high performance portableparallelfile system.In Proceedings of the9th ACM International Conference on Supercomputing,pages385–394, Barcelona,Spain,July1995.[9]D.Kotz.Disk-directed I/O for MIMD multiprocessors.In Proceedings of the1994Symposium on OperatingSystems Design and Implementation,pages61–74.ACM Press,Nov.1994.[10]T.M.Kurc,A.Sussman,and J.Saltz.Coupling multiple simulations via a high performance customizabledatabase system.In Proceedings of the Ninth SIAM Conference on Parallel Processing for Scientific Computing.SIAM,Mar.1999.(a)V olume of communication,fixed input size.SAT(left),WCS(middle),VM(right).(b)V olume of communication,scaled input size.SAT(left),WCS(middle),VM(right).(c)Computation time,fixed input size.SAT(left),WCS(middle),VM(right).(d)Computation time,scaled input size.SAT(left),WCS(middle),VM(right).Figure4:Communication volume and computation time for various applications,forfixed and scaled input data size.[11]B.Moon and J.H.Saltz.Scalability analysis of declustering methods for multidimensional range queries.IEEETransactions on Knowledge and Data Engineering,10(2):310–327,March/April1998.[12]NASA Goddard Distributed Active ArchiveCenter(DAAC).Advanced V ery High Resolution Radiometer Global Area Coverage(A VHRR GAC)data.Available at /CAMPAIGN BIO/origins.html.[13]N.Nieuwejaar and D.Kotz.The Galley parallelfile system.In Proceedings of the1996International Conferenceon Supercomputing,pages374–381.ACM Press,May1996.[14]K.E.Seamons,Y.Chen,P.Jones,J.Jozwiak,and M.Winslett.Server-directed collective I/O in Panda.InProceedings Supercomputing’95.IEEE Computer Society Press,Dec.1995.[15]C.T.Shock,C.Chang,B.Moon,A.Acharya,L.Davis,J.Saltz,and A.Sussman.The design and evaluation ofa high-performance earth science database.Parallel Computing,24(1):65–90,Jan.1998.[16]R.Thakur and A.Choudhary.An extended two-phase method for accessing sections of out-of-core arrays.Scientific Programming,5(4):301–317,Winter1996.[17]R.Thakur,A.Choudhary,R.Bordawekar,S.More,and S.Kuditipudi.Passion:Optimized I/O for parallelapplications.IEEE Computer,29(6):70–78,June1996.[18]The USGS General Cartographic Transformation Package,version 2.0.2.ftp:///pub/software/current。

FIELD SERVICE SOFTWARE ASSISTANCE BROCHURE O S - 8Prepared by:Rick MooreINTRODUCTIONThis is a reference document for Field Service use in diagnosing system problems. The information presented in this chapter is extracted from various OS-8 reference manuals and literature which are listed in the appendix.It is not intended to be a course on OS-8 or a substitute for standard DEC software manuals. However, the topics presented here are some of the more commonly used features and some of the commands that should help you to better serve your customer through an enhanced knowledge of his OS-8 operating system.It is strongly recommended that you be extremely careful using your customer's software as a little knowledge is a dangerous thing. If you do work on a customer's files, be sure to use copies of his system only. Tell him what you feel the problem is and let him take any corrective action.OS-8 consists of an executive and library of system programs which reside on a mass storage device called a "system device". This could be a disk, dectape or floppy unit. The executive supervises the overall program processing and consists of the following four major components:- Keyboard monitor ( KMON )- Command Decoder ( CD )- Device Handlers- User Service Routine ( USR )The Keyboard Monitor provides communications between the user and the OS-8 Executive. The root segment of the monitor resides perminently in memory and occupies 256 words. Commands from the console terminal are interperted and whenever needed, the CommandDecoder, USR, KMON, and ODT are brought into memory in a series of overlays while the contents of the memory used is swapped out to the system scratch area. In this manner it is possible to run a baseline system in only 8K words of memory.The commands that are executed directly from the KMON are:ASsign - assigns a new, user defined device name to a perminant device.DEASsign - restores perminant device namesGET - loads core image files into memory from a deviceSTART - starts execution of a program already in memoryRUn - loads core image (.SV) files into memory from a device and starts executionR - loads core image (.SV) files into memory from the SYStem device and starts executionSAve - creates core image programs on a deviceODt - invokes the Octal Debugging TechniqueDAte - sets / prints the system dateThe Command Decoder is called when a system program needs additional information from the operator concerning files to be acted upon or devices to be used. You are in the Command Decoder whenever the prompt character "*" is issued.Understanding the Command Decoder line format is probably the most important step to successful usage of the OS-8 Operating System. It is as follows:*OUTDEV:OUTFIL.EX<INDEV:INFILE.EX,INFILE.EX/SW1/SW2=N... to translate ...OUTDEV: - the output device (SYS:,RKB0:,DTA0:,LPT:) OUTFIL.EX - the name of the output file and it's extension INDEV: - the input deviceINFILE.EX - the name of the input file and the extensionSW? - an optional switch ... differint for each program=N - numerical value (ie: in direct =N# of columns)There may be 0-3 input files, 0-9 output files, 0-3 option switches, depending on the requirements of the individual program. In several programs, it is not necessary to specify every detail ...certain programs have default values for devices, switches, etc. The only way to be sure of this is to know the program you are working with.Again, the value of learning the command decoder format cannot be overstressed ... the same basic format is used thoughout DEC software. (ie: RT-11, RSTS, etc.)Device Handlers are subroutines which handle data transfer to and from peripheral devices. Device handlers for the particular hardware system you are using are activated by the program "BUILD". These subroutines are then available to all OS-8 programs. It is through the use of device handlers that a sort of "device independence" is acheived.The USR is a collection of subroutines that perform operations of opening and closing files, loading device handlers, program chaining, and calling the CD. The USR provides these functions not only for the system itself, but for any programs running under OS-8.INITIALIZING OS-8Mount the OS-8 System on the appropriate hardware and execute the bootstrap. This may be as simple as pressing a "BOOT" button or require a toggle-in program from the operator's console. Various bootstraps are listed in the appendix.After the bootstrap is executed, the monitor will print a dot "." on the console. At this point, KMON is active and the system is ready to accept one of the monitor level commands listed on page 1.CCLThe Concise Command Language ia a means of providing an easy to understand "English-like" command interface between the operator and the monitor. It translates the commands, chains to the appropriate system programs, passes arguments and filespecs, and starts execution. Any CCL command can be simulated by typing the necessary monitor and CD responses manually. For example:.DIR is equivalent to .R DIRECT*TTY:<SYS:/E=2.COPY RXA1:<RKA0: is equivalent to .R FOTP*RXA1:*.*<RKA0:*.*The use of CCL is optional in OS-8; manditory in OS-78. This is because you cannot normally access monitor level commands in OS-78. There is a way around this; by typing ".SET SYS OS8" it is possible to turn on this attribute.GETTING DIRECTORIES.DIR - types directory of system device on the console.DIR-L - prints directory of system device on line printer.DIR RKB0:-L - prints directory of device RKB0 on line printerSETThe program "SET.SV" is called by the ".SET" CCL command and can be used to modify some of the attributes of the various device handlers. Some useful ones are:.SET SYS OS8 - allows monitor level commands in OS-78..SET SYS OS78 - normal OS-78 mode; CCL commands only.SET SYS INIT - causes the command file "INIT.CM" to be executed upon boot-up..SET SYS INIT [cmd] - causes the command [cmd] to be executed upon boot-up..SET SYS NO INIT - negates the above.SET LPT LA78 - allows PDP-8A (M8316) parrallel port as controller for LA-180 (device code=0570).SET LPT LA8A - restores LPT to normal 0660 device code.SET TTY SCOPE - causes a rubout to actually erase the character from the screen..SET TTY NO SCOPE - causes the rubout to echo the character/slash combination for hardcopy terminals..SET TTY PAUSE - causes the terminal to pause every "height" lines for ease of reading..SET TTY HEIGHT 24 - tells the handler the screen has 24 lines.SET TTY WIDTH 80 - allows 80 character width to VT52 screen*** WARNING ***The command ".SET SYS NO INIT" must be given before attempting to use the "BUILD" program, since execution of the "INIT.CM" file or any CCL command will cause the previous contents of memory and the system scratch area to be altered. Also, since the process of executing this file may entail several overlays, the usefullness of it on any media except disks or diskettes is questionable.OS-8 FILESThere are three standard types of OS-8 file formats used by OS-8 and associated system programs; ASCII, Binary and Core Image (.SV).ASCII and Binary files are packed three characters to every two 12 bit words as follows:-----------------------------------------------| | |Word 1 | Char. 3 | Character 1 || (bits 0-3) | (bits 0-7) || | |-----------------------------------------------| | |Word 2 | Char. 3 | Character 2 || (bits (4-7) | (bits 0-7) || | |-----------------------------------------------0 - 3 4 - 11In Binary files, the binary data must be preceded by one or more frames of leader/trailer code (ASCII 200 code). The first character must be either 100-177 octal (origin setting for absolute binary files), 240-257 octal (a COMMON declaration frame for relocatable binary files), or 300 octal which is an origin setting. The end of binary data is one or more frames of leader trailer code. ASCII and Binary files are terminated by a CTRL/Z code (ACSII 232).A Core Image file consists of a header followed by the actual core image. The header is called the Core Control Block (CCB). It consists of first 128 words of the first block (256 words) of the file. The CCB is a table of information that contains the length of the file, the program's starting address, and the Job Status Word (JSW). The CCB for a program at the time it is loaded into core is always saved in words 200-377 (octal) of block 37 on the system's scratch area. It is placed there by the GET or RUN operations or by the ABSLDR program. This information is then used when performing a SAVE without arguments.FILE NAMES and EXTENSIONSFiles are referenced symbolically by a name of up to six characters followed, optionally, by a period and a two character extension. The extension to a file name is generally used to type the files according to their formats or defaults to particular system programs.In most cases, the user will want to conform to the standard file name extensions established for OS-8. If the extension is not specified for a files, some system programs will append an assumed extension by default. This default extension can be overidden by stating the extension in the CD line explicedly.The most common OS-8 standard default extensions are:SV - core image programsBN - binary programsPA - PAL8 assembly language sourcesBA - BASIC source filesBI - BATCH control filesSY - system headsDG - diagnostic program **BX - DECX8 exercisor modules **X8 - customised DECX8 system exercisor **** refers to psuedo standards imposed by the New England District PDP-8 Diagnostic System.FILE MANIPULATIONSFiles can be transfered between OS-8 devices by using either "FOTP.SV" (File Oriented Transfer Program) or "PIP.SV" (Peripheral Interchange Program) or the CCL commands that call them. These commands and their uses are:COPy - copies files from one device to anotherDELete - deletes files from a deviceLIst - lists an ASCII files on the LPTREName - changes the name of a file in the directory SQuish - eliminates all empty and deleted files on a deviceTYpe - types an ASCII file on the console terminal ZERO - zeroes the directory of a device, deleting all existing files on that deviceFor example, to copy file FOO.PA from RXA1: to RKB0:.COPY RKB0:<RXA1:FOO.PA( note the similiarity between this and the format ofthe Command Decoder Line on page 2.)To copy an entire device using PIP and FOTP type:.R PIP first transfer the system heads *RKA1:<RKA0:/Y/Z*RKB1:<RKB0:/Y/Z.R FOTP now all the files*RKA1:<RKA0:*.* using wildcard transfers*RKB1:<RKB0:*.*For floppies, it is easier since the program "RXCOPY.SV" or the CCL command ".DUPLicate" will copy the entire device.SYSTEM HEADSThe "/Y" option of PIP.SV can be used for system head manipulation. A system head is 50 blocks long and is located at the beginning of the system device. It contains the system bootstrap, the monitor, and all its overlays. System heads are sometimes stored as files on a device for ease of use with the extension ".SY".To move a system head:.R PIP*RKA1:<RKA0:/Yif "RKA1" is a virgin device, a skeleton directory must be created, so type:*RKA1:<RKA0:/Y/ZUSING WILDCARDSCertain commands allow wildcards in the file name specifications. These commands are COPY, DELETE, DIRECT, LIST, RENAME, and TYPE.Wildcards allow a filename or extension to be totally replaced with an asterisk (*) or partially repalced with a question mark (?). Wildcards are particularly useful when doing multiple file transfers. This is illustrated in the following examples:TEST1.* - all files with the name TEST1 and any extension*.BN - all files with a BN extension and any name*.* - all files with any name and any extensionTEST2.B? - all files with the name TEST2 and any extension starting with a BTES??.PA - all files with a PA extension and any name from 3 to 5 characters beginning with TESthe asterisk amd question mark can be used together.* - all files with any extension and with file names of three characters or lessBUILDThe program "BUILD.SV" is the system generation program for OS-8 which allows the user to:1. Maintain and update device handlers in an existing OS-8 system.2. Add device handlers to a new or existing system.3. Change the system characteristics to reflect hardware modifications.Device handlers are supplied with the OS-8 system and are in the format of Binary (.BN) files.To run the Build program, type:.RUN SYS BUILDNOTE:It is important that the user specify the "RUN" command, rather than the "R" command when loading BUILD into core. This will allow the CCB to be stored on the system scratch area for use with the SAVE command!Also, since the system scratch area is used at times when the "INIT.CM" file is executed, it is imperative that the command ".SET SYS NO INIT" be given prior to beginning the BUILD process. After the program is SAVEd, ".SET SYS INIT" can be reinstituted.This matter cannot be overemphisized ... SAving "BUILD" without these precautions will appear to work and the system will boot without failure, however, the next time BUILD is run, it will not work! This is because the proper CCB parameters will have been lost.RUNNING BUILDChanging a system's parameters can be a complicated procedure with too many variables to be explained in this document. For complete instructions on BUILD, see the appropriated OS-8 Manual.- DEVICESSome of the devices that are available in the OS-8 system are:SYS: - the system deviceDSK: - the default device (usually SYS:)RKA0: - "A" side of RK05 drive #0RKB0: - "B" side of RK05 drive #0TTY: - console teletypeLPT: - line printerLQP: - letter quality printer (Diablo)PTR: - paper tape readerPTP: - paper tape punchDTA0: - dectape drive #0DTA1: - dectape drive #1RXA0: - RX01 floppy drive #0RXA1: - RX01 floppy drive #1RL0A: - RL01 area "A" drive 0RL0B: - RL01 area "B" drive 0RL0C: - RL01 area "C" drive 0FUTILThe OS-8 File UTILity program was orginally developed by Jim Crapuchettes of Menlo Computer Associate,Inc., Menlo Park, CA. It is now included within the OS-8 Extension Kit after release V3D, and is also contained on the New England District PDP-8 Diagnostic System after release V8.04.FUTIL enables a user to examine and modify the contents of mass storage devices, including the SYStem device, and is therefore as dangerous as it is useful! It can be used to recover damaged files, repair destroyed directories, patch programs on the mass storage device, and check for bad blocks on the device.It is this last feature that is particularly useful to us in Field Service as we often have questions concerning the validity of a customer's disk or diskette. The following procedure can verify this:.R FUTILSET DEVICE RXA0 floppy drive 0 is the target deviceSCAN 0-755 scans the 756 (octal) blocks on the deviceEXIT returns to OS-8If any bad blocks were encountered, the program would reportBAD BLOCK nnn where "nnn" was faultyThe cause of this could be due to either a bad CRC character due to blown data (can be recopied) or blown format (device must be reformatted). In the case of floppies, the later condition is fatal as they cannot be reformatted.FUTIL can be used to scan devices regardless of their program contents, for example, OS-8, COS 300, or any customer written file structure can be scanned, as long as standard sector format is used.to SCAN an RK05 Disk:.R FUTILSET DEVICE RKA0 or RKA1, etc.SCAN 0-6257 there are 6260 blocksSET DEVICE RKB0 now the other sideSCAN 0-6257EXIT.NOTE:At this time, a note on the "sides" of a disk is in order. The RK05 is broken up into two (2) logical devices called "RKA0" and "RKB0" as the RL01 is broken into three (3) devices called "RL0A", RL0B", and "RL0C" by OS-8. This is because of the system's inability to address the entire disk and the limited number of entries the directories can hold.These "sides" are actually not physical sides (who ever heard of a three sided RL01), but refer (on the RK05) to the first 6260 sectors as "RKA0" and the remaining 6260 sectors as "RKB0". A look at the hardware shows that after the sector counter overflows (at 16 sectors) the heads switch to the other surface. After the sector counter overflows again, the heads switch back and then the cylinder address increments. Thus RKA0 is on the outer tracks of the disk and RKB0 is on the inner tracks.。

Study on Japanese Culture in Tora-san Series FilmsQin Wang1,21School of Foreign Languages，Yan’an University2Graduate School of Integrated Science and Art,University of East Asia, Yamaguchi,JapanAbstract: The comedy directed by Mr. Yoji Yamada, named The Story of Tora-san, is well-known in Japan, and even has a certain influence in Asia and even the world. The reason why the play was so successful was not only rely on it’s humor, but also it’s complete differences from Hollywood, showing the unique social conflicts and family conflicts in Japan, reflecting the unique local customs and the most real Japanese traditional culture, which makes the Japanese audience laugh and has a long-term gratitude and triggers their deep thinking. A study on the Tora-san Series Films is equal to a study of the most real Japanese traditional culture.Keywords: Tora-san; Film; Japanese culture; ResearchDOI:10.47297/ wsprolaadWSP2634-786504.202203011. IntroductionI n 1990, the Japanese went to the Berlin International Film Festival with confidence with the “Tora-san series films”. But to the surprise of the Japanese, it was rejected soon. The reason was that foreigners could not understand why Japanese people were so obsessed to watch “Tora-san”. Although “Tora-san” was not as popular abroad as it was in Japan, and even some foreigners cannot understand why “Tora-san” was so popular in the hearts of Japanese people, even though it was thwarted at the Berlin International Film Festival. But for Japanese people, even if Tora-san dis not receive recognition and understanding abroad, it would not affect Japanese people’s love for Tora-san and their obsession with Tora-san in the slightest. Because in the hearts of Japanese people, “Tora-san” is actually the traditional culture of Japanese people, which shows how unshakable the status of “Tora-san” is in the minds of Japanese people.About the Author: Qin Wang was born in Yan’an, Shaanxi Province, China, in 1984. She is a Associate Professor in the School of Foreign Languages, Yan’an University, China. She as a PhD candidate now, studying in University of East Asia , Japan. Research direction is Japanese culture.Funded project: This research results has been financed by the Horizontal Project of Shaanxi Star Vision Film Co. LTD 《A research on Japanese culture in “ Tora-san “ film series》（YD2019036）.Research on Literary and Art Development Vol.3 No.1 20222. Background of The Story of Tora-san(1) The Great Cultural Revolution in JapanThe first episode of “The Story of Tora-san” was broadcast in 1969 and the last episode was broadcast in 1995, and the whole series lasted 26 years. The film was recorded until the death of Mr. Kiyoshi Watami, who played the lead role of Tora-san. From 1960 to 1979, during the Great Cultural Revolution in China, Japan also saw the Cultural Revolution, which was a cultural revolution that celebrated Mao Zedong’s thought and opposed American imperialism. It was a cultural revolutionary movement that celebrated Mao Zedong’s thought and opposed U.S. imperialism, which was also the “left-wing movement” in Japan. At the beginning of the Cultural Revolution in Japan, students’ movements were the mainstream, and in the 1960s, when the student movement reached a low ebb, the Japanese Red Army took over the banner, and the suppressed Red Army was a microcosm of the society at that time. For many Japanese youth at that time, U.S. imperialism was the symbol of evil and China was the symbol of revolution, and Chairman Mao was the common mentor of all revolutionary youth in the world. It was not until 1979, when China entered the period of reform and opening up, that the external spiritual support for the left-wing youth in Japan was cut off, and the left-wing movements in Japan gradually fell into a low point and eventually disappeared historically.(2) Japan’s “Bubble Economy”From late 1980s to the early 1990s in Japan, Japan experienced the second rapid economic development period after 1960s, which was due to the support of a lot of opportunities, and hit the highest peak of economic development in 1989. But there is no corresponding industrial support, so it looks like bubble, and is later called “bubble economy”. Because of this, in the early 1990s, after the collapse of the bubble, Japanese economy collapsed, which led to a large number of Japanese people losing their jobs and the living conditions of the ordinary people. The ten years after that, the Japanese economy was in a depression of almost 0 growth.3. Japanese Culture in The Story of Tora-sanAlthough there are 48 films in the series of “Tora-san” so far, there are only three core themes running through the whole play: homesickness, travel and love.(1) HomesicknessTora-san appeared on the screen as a typical ordinary civilian with no rights, no status, and no money. The main character Tora-san ran away from home because of an quarrel with his family. He traveled away all the year round, and met all kinds of Japanese women with them. Although the ending was always helpless to break up without any result. However, Tora-san still left his hometown again with regret and set foot in the distance again. His love was undoubtedly a failure, but no matter how frustrated, there were still kind and lovely sisters and family waiting for him to go home in his hometown, tokuga District, Tokyo. He was stubborn and not sophisticated, but his family was always sincerely, tolerant and sincerely looking forward to his return. The little nest upstairs wasResearch on Literary and Art Development Vol.3 No.1 2022 always reserved for him, because it was his home, only because they were his family. However, Tora-san would still think about his sister Cherry Blossom’s happiness after marriage, whether Manman was still worrying about going to school, whether the family were in good health, and so on. Home and family are always spiritual harbors to depend on. Wasn’t it the “home” that Japanese audiences were looking for when the rapid industrialization of Japan led to the loss of family feeling and spiritual home? Perhaps it is because they touch the deepest heart of Japanese audiences that Japanese audiences find some kind of comfort and compensation in the Story of Tora-san.(2) TravelTora-san is a prodigal wandering around, but he still holds hope for life when he runs into a wall outside. Just as the Japanese like traveling, Japan is a big tourist country. Every year in the golden season of traveling, a large number of Japanese people travel around the country. They have a stunning variety of study trips, sightseeing trips and so on. Japan’s modern tourism is even a special scenic spot. The meaning of travel for most Japanese is not simply to watch or play, but to get the insight of life from what they see and think. It can also be said that travel is life. Life is a journey, even if travel is adventure, exploration, experience and growth. This is the lifestyle imprinted on the bones of Japanese people from ancient times to today, just like the wandering surfers. In this way, we can understand why the Japanese love Tora-san so much - because he yearned for freedom, and in these days of wandering around, he silently wrote about his happiness, his troubles and pains, which constitutes the chapter of his life. Although plain, this is a unique and irreplaceable life for him!(3) LoveThe story of the series always ends with his helpless breakup with his beloved woman and regrets that his love as a bottom-level people failed, which is also one of the core of the play, but at the same time, it also reflects the unique Japanese philosophical aesthetics, that is, the “Romantic Esthetics of Lost Love”, which also touches the hearts of many Japanese audiences. Just like Sakuragi Hanamichi in the later “SLAM DUNK”, it is constantly shaken, but still believe in love and still face life positively. This kind of spirit had a unique charm for the lower-level employees living under the strict hierarchy system in Japan at that time, which was one of the important reasons why Tora-san had an unshakable position in Japanese audience.Tora-san’s series of movies reflect the social changes at that time and the changes of general people’s minds through the way of comedy and the story plot. Mr. Yamada cleverly completed a totally different story in a similar scenario, and through the screen, expressed the mood of Japanese people in the social background at that time, so that the Japanese audience laughed, but also generated a yearning and resonance.4. ConclusionIn the last story of the series of movies, Tora-san and Lily met each other for a long time and worked together to achieve the happiness of a man. Looking at the lover’s eventual family, the lily could not help but shed tears. Tora-san raised his courage toResearch on Literary and Art Development Vol.3 No.1 2022embrace the lily, but did not step out after all. The story ends again with regret. If there is another episode, Tora-san might be able to have his long-cherished love, or abandon the lily as helplessly as the previous one, and then wander around on his own. However, the episode ends as usual. However, Tora-san seems to have touched his aspiring happy life even further than his usual story. This end makes the audience feel that the end of the film series is not a farewell, but a restart of his own life. This open-ended ending leaves space for Japanese audiences to reverberate. Everyone has different answers about what life will be like after watching Tora-san. Perhaps longing for future and happiness is exactly what Mr. Yamada wants to convey to audience from his series of works.References[1] Yanlong Yang.

[由于io设备错误]由于IO设备错误篇一: 由于IO设备错误一、不使用机箱上的前置USB口或者是USB延长线，尽量使用主板上的USB接口也就是在机箱后面的USB接口。

原因是：机箱上的前置USB口和USB延长线都是采用USB 1.1结构，而现在的移动硬盘或者U盘都是USB 2.0接口，故在USB 1.1集线器插座上使用则会不定时出错。

即使有些前置USB接口是2.0标准，也可能因为重复接线的原因导致电阻升高，使得USB 2.0接口供电不足。

现在有的电脑有好几个usb接口，一般机箱前面两个，后面四个，其中后面四个中的两个在鼠标键盘接口附近，两个在网卡附近，当我使用前置两个USB接口时移动硬盘没有反应，用在鼠标键盘接口附近的USB接口可以读出来但在拷贝一些文件的时候提示“I/O设备错误，无法运行此项请求“。

最后用在网卡附近的USB接口就一点问题没有。

二、对移动硬盘进行磁盘碎片整理。

原因：移动硬盘经常进行复制、剪贴操作，会在磁道中留下很多的垃圾文件碎片。

也可以使用windows自带的磁盘校检修复的dos 命令chkdsk/f;/p;/v如果长时间没有整理磁盘,偶尔心血来潮要整理得话,推荐先拿它校检一次。

语法:chkdsk [drive:][/p][/r][/f]推荐参数/f,例如:F:\>chkdsk /f 回车三、如果把数据线插到机箱后面电脑还是不能正常地读取数据,还有以下几种可能:引用1:主板比较老，USB驱动程序没装。

3:如果在别人的机子上能用，在自己的机子上却用不了。

这种情况=>硬盘应该没有问题，升级主版驱动试试。

4:如果还是不行的话，看看主板的usb接口是否有问题，试着插另外的usb设备试一下。

5:如果是mp3的话请按照以下方法试一下:取出电池---按住开机键，与电脑连接---打开升级工具，选择机型---下载固件---”固件升级”--”确定”---进行升级ing...；升级完成后就可以了。

ADMe Avamar Data Migration Enabler Compatibility and Interoperability MatrixOctober 1, 2020Overview of ADMeADMe–Avamar Data Migration Enabler is a utility providing automation around the need for extending the retention of Avamar backup data by migrating their content to a different storage medium such as tape, disk or cloud based storage. Backup data is re-hydrated to a staging disk area using a structured top level folder layout for organizational purposes and from there can be automatically backed up to a tape application using a standard file system backup. When staged to cloud enabled storage files are automatically uploaded to it potentially eliminating the need for a tape application. The migration process entails three distinct phases, a client/backup selection phase to identify the backups to act on, a rehydration or staging phase followed by an optional tape backup or cloud synchronization phase. These phases are automated end-to-end using ADMe Job policies eliminating the need for any manual intervention or localized scripting. Each phase can also be performed interactively or by job policies as required.ADMe Interoperability Matrix1.Only FS backups are supported from a Networker dedup node (deprecated)2.Best effort support for recovery from existing AER tapes1.Rehydrate mode recovers Avamar backup data to its original file format with no dependency on Avamar in order to utilize the file data2.Archive Mode recovers Avamar backup data to a streamed PAX file format similar to that used by AER but has a 100% dependency on the need for an Avamar GSAN to import it back to in order to be able to recover its contents3.OS versions chosen must be valid and supported by both Avamar and the tape application being used1.The use of non EMC tape applications are the responsibility of the user2.Avamar used as a target destination when migrating from a GSAN only or GSAN + DD system to a GSAN/DD Griffin system3.Backup Exec 2012 and previous versions are supported4.Full end-to-end automation only available with a Windows staging serverworker version should be latest supported by Dell EMC1.Cloud enabler tools other than EMC Geo-Drive are the responsibility of the user2.Amazon support is the responsibility of the user3.Support for any cloud provider is feasible assuming its object storage can be presented via iSCSI, CIFS or NFS4.Archive mode should be used as a last resort due to its dependency on the need for Avamar GSAN storage to which it mustbe imported to convert it to a usable format5.All future support of Cloud Array has been deprecated as the CA product is discontinuedNotes:1.NDMP for Isilon requires Avamar version 7.1 or higher2.Oracle has a dependency requiring it to be re-ingested to an Avamar system when recovering it from tape3.SAP with Oracle will be treated as flat files and may require user action to ensure appropriate backups are being selected.Due to backup selection challenges, consider SAP support as a best effort only.rge NDMP backups recovered in Archive mode may result in a PAX file size exceeding the max file size permitted by the staging server OS and filesystem5.NDMP redirected recoveries to Windows or Linux FS does not preserve NAS specific ACLS or Extended File Attributes for Windows6.NDMP Support for NetApp is discontinued due to its poor rehydration performance from Avamar and other technical challenges7. A Celera/VNX using its Space reduced Backup feature, must have this feature disabled by setting it to 0 and a new Lvl-0 backup performed afterwards. Refer to ETA 495263 available from ADMe home page8.SharePoint support is limited as it performs a directed recovery of the complete backup content to an out of place directory which may not be useful in all situations。

Personal Background：Michael Dell Dell Computer 3-year return：4，200% Age：45 CEO since：1984个人资料：迈克尔·戴尔戴尔计算机3年内的利润：4200%年龄：45岁成为首席执行官的年份：1984年。

It's often said in business that some event—— good or bad——happened on a particular chief execu tive's “watch.” It's a nautical expression suggesting that the enterprise is a ship and that this particular chief executive took the helm at some moment mid-journey，just in time to land a great white whale or hit an iceberg. Good or bad，that course and the event that followed were already set before the CEO entered the pilothouse. The idea is that CEOs come and go，but great companies go on forever.商界经常称某些事件——无论是好的或者糟糕的——常常发生在某个特别的首席执行官的值班时间。

这是海员的说法，说明企业就是一艘船，而这位特别的首席长官在航行途中某段时间掌着舵，恰好此时捕得一条巨大的白鲸或者撞上了冰山。

好的或者糟糕的路线以及紧随其后的结果在CEO进入操舵室前就已成定局了。

这种观念就是说CEO们变来变去，但是好的公司会一直在运转。
