Developed using Java, the Eclipse platform can be used to develop rich client applications, integrated development environments, and other tools. Eclipse can be used as an IDE for any programming language for which a plug-in is available.The Java Development Tools (JDT) project provides a plug-in that allows Eclipse to be used as a Java IDE, PyDev is a plugin that allows Eclipse to be used as a Python IDE, C/C++ Development Tools (CDT) is a plug-in that allows Eclipse to be used for developing application using C/C++, the Eclipse Scala plug-in allows Eclipse to be used an IDE to develop Scala applications and PHPeclipse is a plug-in to eclipse that provides complete development tool for PHP.LicensingEclipse platform and other plug-ins from the Eclipse foundation is released under the Eclipse Public License (EPL). EPL ensures that Eclipse is free to download and install. It also allows Eclipse to be modified and distributed.Eclipse ReleasesEvery year, since 2006, the Eclipse foundation releases the Eclipse Platform and a number of other plug-ins in June.1.Eclipse8Eclipse 9Downloading EclipseYou can download eclipse from /downloads/. The download page lists a number of flavors of eclipse.The capabilities of each packaging of eclipse are different. Java developers typically use Eclipse Classic or Eclipse IDE for developing Java applications.The drop down box in the right corner of the download page allows you to set the operating system on which eclipse is to be installed. You can choose between Windows, Linux and Mac. Eclipse is packaged as a zip file.Installing EclipseTo install on windows, you need a tool that can extract the contents of a zip file. For example you can use:∙7-zip ∙PeaZip ∙ IZArcUsing any one of these tools, extract the contents of the eclipse zip file to any folder of your choice.2.Launching EclipseOn the windows platform, if you extracted the contents of the zip file to c:\, then you can start eclipse by using c:\eclipse\eclipse.exeWhen eclipse starts up for the first time it prompts you for the location of the workspace folder. All your data will be stored in the workspace folder. You can accept the default or choose a new location.1011If you select "Use this as the default and do not ask again", this dialog box will not come up again. You can change this preference using the Workspaces Preference Page. See the Preference tutorialpage for more details.Eclipse 12Parts of an Eclipse WindowThe major visible parts of an eclipse window are:∙Views ∙Editors (all appear in one editor area) ∙Menu Bar ∙ ToolbarAn eclipse perspective is the name given to an initial collection and arrangement of views and an editor area. The default perspective is called java. An eclipse window can have multiple perspectives open in it but only one perspective can be active at any point of time. A user can switch between open perspectives or open a new perspective. A perspective controls what appears in some menus and tool bars.3.EclipseA perspective has only one editor area in which multiple editors can be open. The editor area is usually surrounded by multiple views. In general, editors are used to edit the project data and views are used to view the project metadata. For example, the package explorer shows the java files in the project and the java editor is used to edit a java file.The eclipse window can contain multiple editors and views but only one of them is active at any given point of time. The title bar of the active editor or view looks different from all the others.The UI elements on the menu bar and tool bar represent commands that can be triggered by an end user.Using Multiple WindowsMultiple Eclipse Windows can be open at the same time. To open a new window, click on the Windows menu and select the New Window menu item.Each window can have a different perspective open in them. For example you could open two Eclipse windows one in the Java perspective and the other in the Debug perspective. The window showing the Java perspective can be used for editing the java code and the window showing the debug perspective can be used for debugging the application being developed.13Eclipse 14T ypical Eclipse MenusThe typical menus available on the menu bar of an Eclipse window are:∙File menu ∙Edit menu ∙Navigate menu ∙Search menu ∙Project menu ∙Run menu ∙Window menu ∙ Help menu4.Plug-ins can add new menus and menu items. For example when the java editor is open, you will see the Source menu and when the XML editor is open, you will see the Design menu. Brief Description of Menus15Customizing MenusThe visible menu items on a menu depend on the installed plug-ins and customization done using the Customize Perspective dialog box.16Eclipse 17About ViewsEclipse views allow users to see a graphical representation of project metadata. For example the project navigator view presents a graphical representation of the folders and files associated with a project and properties view presents a graphical representation of an element selected in another view or editor.An eclipse perspective can show any number of views and editors. All editor instances appear in a single editor area, whereas views are placed inside view folders. A workbench window can display any number of view folders. Each view folder can display one or more views. Organizing ViewsThe following picture shows four views arranged in a view folder.The picture given below shows the same four views arranged in two view folders.5.Moving ViewsTo move a view from one view folder to another, just click on the view title and drag to the title bar area of another view folder. The green line shown below is a result of dragging the title bar of the Properties view from one view folder to the title bar area of another view folder. The Properties view can be moved to where the green line is by releasing the mouse button and sending out a drop event.Creating View FoldersView folders can be dynamically created by dragging the title bar of a view to anywhere outside the editor area and title bar of another view folder. As you drag the title bar around, green lines will indicate where exactly the new view folder will be created.Moving the drag icon to the bottom of a window allows you to create a view folder that spans the entire width of the window. Moving the drag icon to the left or right edge of window allows you to create a view folder that spans the entire height of the window.18Opening a viewTo open a view, click on the Window menu and select the Show View menu item.19Clicking on the Other menu item brings up the Show View dialog box that allows you to locate and activate a view.20The views are organized by category. To quickly locate a view, just type the name of a view into the filter text box. To open a view, select it and click on the OK button. The subsequent pages of this tutorial introduce you to a number of useful views.21End of ebook previewIf you liked what you saw…Buy it from our store @ https://22。

PS501-SCASCA is short for “Safety Code Analysis”. In order to be able to use ST (Structured Text), FBD (Function Block Diagrams) and LD (Ladder Diagrams) for safety programming in CoDeSys 2.3, you have to follow certain coding guidelines.SCA can read your CoDeSys project and check it against those guidelines, flagging any problems.The user interface of SCA resembles that of CoDeSys very closely, so you should already be familiar with most of what you see.1. Installation NotesPC Hardware/Software Requirements:Any standard PC with Windows OS like XP Professional (32 bit) or Windows Vista or Windows7 will support the installation of SCA. Your PC shall have adequate memory (SCA needs around 2 MB only) and necessary administrator rights. SCA works as a stand-alone piece of software independent of Control Builder Plus installation and takes only a few seconds to complete the installation. However this depends on the speed of your processor.Click on the “.exe” file provided to start the installation process. Make sure that the necessary “.msi” file is located in the same directory as of the exe file. You will be guided by the software to complete the simple installation process.2. Workflow for project analysis–Export the project from CoDeSys–In the CoDeSys main menu, select “Project > Build”.–Make sure that CoDeSys reports no errors or warnings.–In the main menu, select “Project > Export”.–Ctrl-click to unselect “Workspace” and …PROFIsafe“ folder and then click “OK”.–Select a location and filename to save the export to, and click “Save”.–Open the exported file in SCA–In SCA, press “Ctrl-O”, or–in the main menu, select “File > Open CoDeSys export...”, or–click the “Open” button on the far left of the toolbar.–In the file open dialog, select the file just exported from CoDeSys.–You can also drag and drop a file onto the SCA window instead.–SCA immediately analyses your project and displays any problems found in the message list on the bottom.–Click on a message to display the source of the affected module and to and highlight the exact location where this prob-lem occurred.–Hover the mouse pointer over the selected message to see a resolution suggestion. (You may need to select “Options > Enable tooltips” first.)–Press F1, or select “Help > Help on this problem” from the main menu, to call up a help page on the problem selected.You can also right-click on any message and select “Help” from the context menu.–If you want to concentrate on the more serious problems first, select “Options > Show only errors” from the main menu.(This will add a message stating that you disabled warnings to remind you.)–If you want to tackle all problems of the same type together, select “Sort > by problem number” from the main menu.–Apply any changes required to your sources in CoDeSys. You don’t have to close the export in SCA in order to do this.–Repeat until SCA doesn’t show problems any more.–To reopen the export last opened:–Type “Ctrl-N”, or–in the main menu, select “File > Reopen”, or–click on the file name displayed in the toolbar.–To open an export recently opened:–In the main menu, select it under “File > Open recently used”, or–click on the small arrow next to the file name displayed in the toolbar, and select the export from the list displayed.–Print reports as needed.3. Format of the problem messages3.1. ExampleError 0180: Datatypes (H 9): Direct complex type declarations in variable lists are not allowed.3.2. ExplanationEach message contains the following parts:–Severity - this may be one of–“Error” - major problem that you must remove;–“Warning” - minor problem that you must remove;–“Manual” - a situation where SCA cannot determine whether a problem really exists or not.Print the “Manual check items” report and manually check for these problems;–“Remark” - additional information.–Problem type number.–Location, given by–name of the POU, global variable list, or type declaration, followed by–line or network number in parentheses. If the problem occurred in a POU,–“H” indicates a line number in the declaration header,–“B” indicates a line number in the body of an ST POU, and–“N” indicates a network number in an FBD or LD POU.–The problem message.4. Library definition filesIn order to be able to correctly check certain of the coding guidelines, SCA needs to know the definitions of POUs and variab-les contained in libraries. Some libraries are known to SCA by default (see Help for more details).If your project references libraries other than the standard libraries, you must provide the information contained in these libraries to SCA as follows.–Open your library project in CoDeSys 2.3.–Make sure the library project compiles without errors and warnings.–Export the complete library project from CoDeSys, as described above.–Open the export file in SCA.–In the main menu, select “File > Save library definition...”.–The save dialog opens in the “Library definitions” subfolder of the directory where SCA is installed.Save the library definition file only here, as SCA will otherwise not be able to find it.–If, in projects using the library, it is referenced by a different name, replace the name provided by SCA by that name.–Click “Save” to save the library definition.2 PS501-SCA | Read Me 3ADR020066K0202。

Power management is a process that allows displays and computers (CPU, hard drive, etc.) to enter low-power states when sitting idle.12. Users can adjust how long your computer waits before sleeping or hibernating. Please refer to the user manual or website of O.S. provider for further information.13. Lowest power state means the state with the lowest power demand found in a computer. This mode may be entered or left by either a mechanical means or via automatic means14. Idle state means a state of a computer in which the operating system and other software havecompleted loading, a user profile has been created, the computer is not in sleep mode, and activity is limited to those basic applications that the operating system starts by default9. The computer is automatically set to sleep after 30 minutes of user inactivity.2. Inactive displays with enabled power management enter low-power modes by turning off monitor output,which can save $10 to $30(USD) per monitor annually3. The low power modes of inactive computers can involve reducing power consumption or spinning down the hard disk, which can save $15 to $45(USD) per desktop computer annually.10. To wake your computer, click the mouse, press power button, or press any key on the keyboard.11. For windows system, Notebook Computers will enter into hibernation after 360 minutes5. Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when users want to start working again.6. Hibernation is a power-saving state designed primarily for laptops. Of all the power-saving states in Windows, hibernation uses the least amount of power.7. Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate.

These commonhardware items include:>Commodity personal computers(PC) and components>PC host (across devices)>PC IOS (across devices)>L3Harris personal computer imagegenerator (PC-IG) (across devices)>L3Harris IOS console components>L3Harris debrief components>Cockpit and support componentsinset image goes up hereCLICK in this RECTANGLE ANDTHEN GO TO FILE -> PLACE TOINSERT IMAGEof hardware platforms complicates simulator-to-aircraft configuration concurrency throughout the aircraft’s operational life.L3Harris maintains a common core of software that has been delivered on Gould, Encore, SGI and personal computer hardware platforms, including L3Harris SimuView® image generator. This focus on software commonality enables the leveraging of development efforts from various sources, including U.S. Navy, FMS and Link IR&D. Software commonality facilitates updates to all F/A-18 simulation devices—from Deployable Readiness Trainers (DRT) to TOFTs—with a single investment. TACTICAL OPERATIONAL FLIGHT TRAINERL3Harris SimuView® image generation system and scalable SimuSphere® visual display are combined to provide exceptional visual cueing realism necessary to support F-16 pilot training. SimuView employs off-the-shelf personal computer hardware and video cards, in addition to hardware independent image generation softweare. SimuSphere partial dodecahedron frame design—which is marked by seamless facet tolerances—allows for 3, 5, 7 or 9 display panels that provide pilots anywhere from 180 degree to 360 degree horizontal field of view.NIGHT VISION GOGGLE STIMULATIONOwning the night is key to successful F-16 air campaigns. L3Harris has developed a Night Vision Training System (NVTS) that provides night vision goggle (NVG) training as an integrated product solution. L3Harris NVTS couples the image generator, NVG sensor stimulation, head tracking, user-supplied NVG goggles and correlated databases into a single integrated system.DISTRIBUTED TRAINING NETWORKSL3Harris F/A-18 trainers are designed to support both local and wide area networking, enabling multiple simulators to participate in an exercise scenario. Depending on customer requirements, L3Harris also can provide a distributed briefing, mission observation and debriefing capability.INSTRUCTIONAL SYSTEMSA modern personal computer-based Instructor Operator Station (IOS) provides a workstation designed for efficient and effective training scenario execution. The IOS provides individual control over a single device or can control multiple devices in a distributed training environment.When combined with a scalable video wall consisting of plasma displays, the IOS becomes an integral part of a mission observation facility. The L3Harris IOS includes an entity station consisting of a stick, throttle and visual display.The heart of Tactical Operational Flight Trainer (TOFT) is a system and software architecture that promotes hardware independence. The continuous evolution of hardware platforms complicates simulator-to-aircraft configuration concurrency throughout the aircraft’s operational life.L3Harris maintains a common core of software that has been delivered on Gould, Encore, SGI and personal computer hardware platforms, including L3Harris SimuView® image generator. This focus on software commonality enables the leveraging of development efforts from various sources, including U.S. Navy, FMS and IR&D. Software commonality facilitates updates to all F/A-18 simulation devices—from Deployable Readiness Trainers (DRT) to TOFTs—with a single investment.TACTICAL OPERATIONAL FLIGHT TRAINERThe L3Harris TOFT, built and delivered for the F/A-18 Hornet and Super Hornet aircraft, has been designed to support the full Strike/Fighter training continuum. From Fleet Replacement Squadron (FRS) or basic flight through the most complex of tactical employment training, F/A-18 TOFTs deliver highly realistic simulations that can support singleship individual, multi-ship team and combat mission rehearsal training.F/A-18 TRAINING DEVICESThis open and standardized hardware architecture has been designed to beL3Harris-device independent, fully supporting F/A-18 training and minimizing logistics requirements today and in the future. Each of these tiers of commonalitysupport and reside across F/A-18 devices.The TOFT provides a training-proven solution for stand-alone, as well as local and long-haul networked training requirements, that provides an interoperable, scalable, full spectrum combat training environment. The TOFT is the first F/A-18 Defense Modeling and Simulation Office (DMSO) HLA-certified training device.The F/A-18 TOFT initially leveraged the L3HarrisHarris Link legacy F/A-18 WTT high-fidelity software to provide extensive procedural and weapons system training capabilities. The TOFT has evolved to a PC-based architecture, maximizing COTS and reuse. The PC-based TOFT, along with its modular software architecture, facilitates technology insertion and simulator/aircraft concurrency.The TOFT’s proven visual display systems, SimuSphere® and SimuSphere® HD, provide a very high-resolution, scalable field-of-view capability. With SimuSphere and SimuSphere HD, the TOFT footprint has been minimized, greatly reducing required facility size and power requirements. The modular TOFT can also be adapted as a deployable system for use in the field, on the road or aboard an aircraft carrier.Since the TOFT was designed with the tenets of modularity and scalability in mind, components can be tailored to exactly meet defined training and system requirements. These include unique avionics models, instructor and role player stations of varying fidelity and a brief/debrief system that allows students and instructors to fully reconstruct and manipulate an entire training event to maximize the effectiveness of the total learning experience.As a result, the F/A-18 TOFT presents the Hornet and Super Hornet Strike/Fighter a superior training environment, shaped in their requirements and founded on tactical relevance.TRAINING CAPABILITIESFor both U.S. and international employment, the TOFT supports all tactical and non-tactical training tasks associated with all variants of the F/A-18. When required, independent F/A-18 pilot and weapon sensor officer simulators that are networked can be surrounded by Link’s advanced 360 degree visual display systems. The TOFT provides proven high-fidelity crew station(s), displays, switches, validated aero, avionics systems and aircraft subsystems. Scalable TOFT SimuSphere visual system displays can provide up to a 360 degree field-of-view.Following are some of the missions and mission areas warfighters can train towards in the TOFT:>Individual or team training>Single-ship and multi-ship employment>Normal and emergency procedures>Basic air work, formation and local area operations>Instruments, navigation and all weather operations>Night vision goggle training and employment>Airfield takeoff and landings, carrier operations>Air-to-air and air-to-surface weapons training>Air-to-air and air-to-surface tactical employment training>High Off Bore Sight weapons employment training>Digital Close Air Support>Precision Target Acquisition training>Multi-functional Information Distribution>System (MIDS) training>Low altitude operations>Surface-to-air threat and counter tactics training>Mission rehearsalSCALABLE VISUAL DISPLAY TECHNOLOGYDelivering high performance imagery is the job of L3Harris’s patented SimuSphere and SimuSphere HD visual display systems. With excellent performance, seamless facet tolerances and flexibility, SimuSphere uses a dodecahedron frame design allowing for three, five, seven or nine display panels producing 180 degree to full 360 degree field-of-views.SimuSphere was the first small footprint system to produce constant resolution and brightness across all facets for a fully immersive visual experience.SimuSphere HD’s state-of-the-art digital projectors provides industry-leading sharpness and brightness. A fully integrated visual display, SimuSphere HD supports sharp, bright heads-up-displays; high-fidelity, physics-based stimulated night vision goggle capability; and is compatible with Helmet Mounted Cueing Systems and future visual/ sensor capabilities.EMULATED MISSION COMPUTER AND DISPLAYSL3Harris developed the first and only true emulation of the F/A-18 aircraft mission computers in 1998. This revolutionary software allows the aircraft operational flight program to be run directly by the simulator, in its native form, without preprocessing of any sort. The result is the highest fidelity cockpit presentation and facilitates ease of simulator concurrency with the aircraft at a greatly reduced cost.The combination of the mission computer emulation and faithful simulation of aircraft displays supports all aircraft operational display modes including:>Color digital map simulations>Full fidelity IR simulations>Correlated weapons video>Spatially correct HUD representation>Correlated A/A and A/G radar simulations>Distributed TrainingL3Harris has provided integrated F/A-18 training since 1983. In 2002, L3Harris achieved the first and only DMSO certification of HLA compliance on a four-ship of L3Harris F/A-18 simulators based at Naval Air Station Lemoore, Calif. Today, L3Harris F/A-18 devices are participating in multi-ship training exercises across the globe with various disparate training systems including air, land, and sea simulators.To assist in capturing the relevant training points of these complex, large scale exercises, L3Harris has a fully developed distributed briefing, mission observation and debriefing capability to round out the suite of services that provide F/A-18 operators with the most complete training system in the world.SYNTHETIC COMBAT ENVIRONMENTL3Harris open and modular CTSA supports the use of the best synthetic combat environment (SCE) or multiple SCEs, including commercial-off-the-shelf products for the training mission.There are many SCEs available on the commercial market that will continue to evolve over time, which is why L3Harris CTSA is designed to provide the flexibility and modularity needed to support future training requirements and technology growth. For stand-alone and networked training, L3Harris F/A-18 SCE provides the ideal tactical and natural environment to support the entire F/A-18 training continuum.L3Harris sophisticated F/A-18 SCE includes aircraft, missiles, ground vehicles, electronic warfare effects, weather and time-of-day controls. Performance and effectsof tactical threats and environmental effects are user definable and menu driven, enabling rapid integration of current threat, Order of Battle and environment information into the simulation.INSTRUCTOR OPERATOR STATIONThe new L3Harris F/A-18 IOS has been human factors and F/A-18 instructor-engineered to provide a workstation designed for efficient and effective training scenario execution. The F/A-18 IOS is a PC-based and HLA-connected component of L3Harris F/A-18 training systems.The IOS provides individual control over a single device, or can control multiple devices in a distributed training environment. The Microsoft Windows® -based L3Harris IOS provides the capability to initialize, support, control and monitor all aspects of a training exercise. When combined with a scalable video wall consisting of plasma displays, the IOS provides a state-of-the-art mission observation facility.DEPLOYABLE READINESS TRAINER The DRT can be thought of as arepackaged F/A-18 TOFT, providing reduced footprint and focused, tactically-relevant physical cockpit fidelity at a significantly reduced cost. The DRT uses the same computational system and software as the TOFT, so it provides the identical, accurate, high-fidelity OFP/SCS and systems replication provided by its higher physical fidelity relative.The system was designed to support deployed operations, with a fidelity focused on tactical employment and tactical procedures-based training associated with advanced training requirements.Using the same HLA architecture foundin the TOFT, L3Harris-built tactical task trainers can be fully integratedinto a distributed network to provide a fully interoperable force multiplier, friendly or hostile. The DRT has two visual systems. A flatpanel display can be used for a forward out-thewindow visual when a wide field-of-view is not needed.If a greater field-of-view or field-of-regard is required to support more complex and dynamic training, the L3Harris Fast Jet Helmet Mounted Display and night vision goggle solutions can provide a highfidelity, 360 degree visual environment for both day and night operations.t 817.619.2000 | f 817.619.3555 *****************This document consists of basic marketing information that is not defined as technical data under ITAR Part 120.10.

With this component, instructors, operators or other event participants can take control over any threat aircraft or simulated blue aircraft to provide dynamic interactive control.Following are some of the roles this component can fill: >Lead for wingman training >Wingman for lead training >2-ship lead for 4-ship lead training >Tailoring threat air presentationThe entity station or IFT can be integrated with either an IOS stealth view, or it can be integrated with low-cost goggles providing a simple 360 degree field-of-view, to provide the entity pilot with a dynamic, interactive capability. DEBRIEFING SYSTEMThe L3Harris debrief system was born out of a cooperative effort between current and qualified FA-18 tactical aircrew, systems design engineers and training psychologists. The debrief system captures all mission event data. This data is stored and available for later use during mission analysis and debrief.To effectively present this information to maximize teaching and learning, L3Harris uses a state-of-the-art video wall. The L3Harris video wall is a scalable debrief system, comprised of multiple wall-mounted flat screen color displays and interactive whiteboard technology.These displays provide crew station display repeater function, a God’s-eye view of the mission replay over associated tactical maps or geographic terrain representations and a variety of images, including a stealth viewer, an event timeline, 3-D or 2-D displays and pair data displays that fully support multi-ship tactical debriefing.During a mission debrief, the mission commander may use the map to take the trainees through the planned mission prior to an event replay as well as annotating comments, flow and other points of interest using the interactive whiteboard technology. Central to the debrief system capability is the video playback system, integrated into the debrief event controls. Variable forward and reverse rates of playback speed are supported.In addition, the system captures and displays instructor-selected performance and execution data on an event timeline, as well as supporting manual event marking by an instructor or operator. In short, the debrief system provides the instructor and trainee alike a Strike/Fighter pilot-designed teaching and learning aid that will maximize the effectiveness of a training event.1025 W.

SCE: A Fully Integrated Software Tool for Beowulf Cluster SystemPutchong Uthayopas, Thara Angskun, Somsak Sriprayoonskul, and Sugree PhatanapheromParallel Research Group, CONSYLDepartment of Computer Engineering, Faculty of Engineering Kasetsart University, Bangkok, ThailandAbstractOne of the problems with the wide adoption of clusters for mainstream high performance computing is the difficulty in building and managing the system. There are many efforts in solving this problem by building fully automated, integrated software distribution from several open source software. However, these sets of software come from many sources and never been designed to work together as a truly integrated system. So, some problem is still remaining unsolved.With the experiences and tools developed to build many clusters on our site, we decided to build an integrate software tool that is easy to use for cluster user community. This software tool, called SCE (Scalable Computing Environment), consists of a cluster builder tool, complex system management tool (SCMS), scalable real-time monitoring, web base monitoring software (KCAP), parallel Unix command, and batch scheduler (SQMS). This software run on top of our cluster middleware that provides cluster wide process control and many services. MPICH are also included. SCE are truly integrated since our group builds all tool but MPICH. SCE also provides more than 30 APIs to access system resources information, control remote process execution, ensemble management and more. These APIs and the interaction among software components allow user to extends and enhance SCE in many ways. To make things easy, the installation and configuration in SCE are fully automated completely by GUI. This paper will discuss the current SCE design, implementation, and experiences. SCE is expected to be available as a developer version in June.1 IntroductionBeowulf Cluster [1] has been accepted as a platform that creates a great deal of impact in a HPC area. The reason is that Beowulf cluster bring extremely high computing power to scientists and engineers at a very low cost. As a result, the use of this platform rapidly increases during the last few years. Nevertheless, building and operating a Beowulf cluster requires many expertises. The problem is more severe as the system size grows. To address this problem, many research groups [2][3] have built many tools that help reduce the complexity of building and maintaining Beowulf clusters.Recently, there are many packages such as SCYLD [4] and Oscar[5] that attempt to provide an integrated cluster distribution that includes all necessary tools in one package. Nevertheless, there are still some problems left unsolved. First, the configuration of each tool is still separated. Second, these tools usually start many components with duplicated functions. This is inefficient and wastes a lot of system resources. By building a fully integrated cluster environment, all these problems can be eliminated totally.In this paper, SCE a fully integrated software tool for Beowulf cluster is introduced. SCE consist of a set of tools includes cluster builder tools, system management tool, real-time monitoring system, cluster middleware, batch scheduler, parallel Unix command and much more. These tools are building by the same research group and hence, the integration of these tools are considered since the beginning. Therefore, the installation and operation of SCE are very easy for users and system administrators.The remainder of this paper is organized as follows. Section 2 explains some of the important term used. Section 3 gives an overview of SCE, follows by the description of SCE installation process in Section 4. Section 5 briefly describes the functionality of cluster builder tool called Beowulf Builder. Section 6 discusses about SCMS cluster management tool follows by the discussion of SQMS, batch-scheduling system in SCE. Section 8 presents the current status of SCE. Finally, Section 9 presents the conclusion and future work.2 TerminologyIn this section, the terms used through out this paper are defined. First, this paper assumes that standard cluster system consists of one or more master node and many of the slave nodes. This master node responsible for the management of the system and also act as a centralize file server for small cluster. Slave node is a complete computer that usually used to perform the computation. Slave node can be either diskless node or disk full node. For diskless node, the operating system and root file system is totally stored on master node. Although diskless node can have a local disk, this local disk is used for data storage and swap space only. In contrast, diskfull nodes use local storage as a boot device that store completeoperating system image. All operating system start up can and will be done locally. Master and slave nodes are connected through one or more interconnection network. This network is primarily used for message passing in parallel programming.3 Overview of SCESCE consists of a set of feature rich software environment that allows users to easily build and maintain cluster configuration, monitoring various performance parameters, schedule sequential and parallel job. As shown in Figure 1, SCE consists of 4 main components. First, Beowulf builder is a software tools that create cluster and maintain cluster configuration. User use Beowulf Builder to automatically create all necessary configurations that allows a set of diskless nodes to remotely boot from master node. Once user finishes the installation, a middleware layer called KSIX [6] controls normal operations of a cluster. KSIX always run in background and provides many services to upper layer software tools. There are 2 main software systems running on top of KSIX, that is SCMS [7] cluster management system and SQMS batch scheduling system. SCE also include MPICH [8][9], one of the most widely use MPI implementation so user can start programming in parallel under SCE immediately after the installation finish. In the following section, each part of the system will be explained in more detail.Figure 1: SCE ArchitectureThe clear advantage of SCE approach in integrating all cluster software tools together are as follows.• Reducing the needs to do a complicated setup of multiple tools and keep the global configuration consistent.• Sharing of software components make the system smaller, consume less system resources, and works faster.• Software component interact better since they are design from the beginning to work together. For instance, batch scheduler can usemiddle service for process control and use performance-monitoringservices to do a better resources management.4 SCEInstallationA typical cluster configuration that SCE expect to see is as shown in Figure 2. SCE assume that a Beowulf cluster system consists of one or more master node and many slave node that connected through IP network. For users, SCE comes in 2 formats: A downloadable tar/gzip format or CD ready ISO file format. Once unpacked, a directory will be created. This directory will be referred in a subsequent explanation and SCE home directory.Figure 2: Typical SCE based Beowulf cluster system ArrayFigure 3: SCE Installation processSCE installation begins by running file name setup found in SCE home directory. This operation start a component of SCE called SCE Master Installer. Main function of SCE master installer is to install the rest of SCE packages and additional library using rpm tool. The installation process is shown in Figure 3.Basically, each SCE tool can be divided into 3 parts: Install Wizard that helps configure the tool initially, Tools Body which is the real working part of the tools, and Uninstall Wizard that do the cleanup. Therefore, in SCE, one can easily added more tools with only a minor modification in SCE master Installer. In addition, users will have an option of de-installation of a particular tool of required. During the installation, SCE master will run in the background and automate the invocation of each tool’s wizard. The goal of SCE installation is to allow users to finish the installation process up to the point that MPICH can run without typing anything. This is possible by defining a good defaults and using a standard cluster platform.Figure 4: Screen shots of SCE 1.0 (Alpha version) Installation5 Building Cluster with Beowulf BuilderTwo major approaches are used to remotely installed slave nodes. LUI [10] software from IBM enables users to remotely boot slave node first, then use rpm command to remotely install RPM based packages are later. VA System Imager[11] uses a different approach by having user install a complete slave node called golden slave first. Then, there are utilities that help user grab the configuration to centralize server and push it to multiple slave node.In SCE, a tool called Beowulf Builder is built for the same purpose. The installation process of Beowulf builder use a little of previously described approaches. Basically, SCE assume that user must install the master node first, then run Beowulf builder later. Once running, Beowulf builder will have a wizard that get basic configuration information from users about slave nodes. The screen shot of Beowulf Builder Wizard is as illustrated in Figure 5.Figure 5: Screen Short of Beowulf Builder WizardAfter the configuration, Beowulf builder automatically extracts required system files and library to build root file system and /usr file system for each diskless slave node in /tftpboot. User have can use Beowulf builder to generate a boot floppy or binary image for NIC boot prompt. The easiest way to boot slave node is to insert this so-called “magic boot floppy” into floppy disk drive of slave node and power on that node. The boot process start automatically using combination of DHCP, TFTP based remote boot protocol. After slave node has been started, it will use NFS root file system and /usr file system on server. This approach makes the installation very automatic and work well for small cluster to about 100 nodes clusters//// SCE Cluster Building Process//main(){Install Linux RedHat Package;SCEInstaller();}void SCEInstaller(){InstallKSIXrpm(); InstallSCMSrpm();InstallKCAPrpm(); InstallSQMSrpm();InstallExternalPackage();// now we have packages in place on master nodeConfigandBuildCluster();KSIXWizard(); SCMSWizard();SQMSWizard();// OK We are readyRebootMaster();forallslave {BootSlavenode();}}void InstallExternalPackage(){InstallPIL(); // Python Image LibraryInstallLibprg(); // our own component}void ConfigandBuildCluster(){GetUserDefineNodeSetParameter();Loopcreatconfigure();bootmedia=GetBootMediaFromuser();Switch(bootmedia) {case Bootrom : Createbootromimage();break;case Floppy : CreateBootFloppy();break;case CDROM : CreateBootCDROM(); // not support yetbreak;case FLASH : CreateBootFlashImage(); // not support yet break;}}void BootSlaveNode(){SlavesendDHCP(); GetDHCPreply();LoadKernelbyTFTP(); BootKernel();MountNFSroot(); NormalBoot();}Figure 6: Beowulf Builder Boot ProcessProcess of building a cluster are as shown by pseudocode in Figure 6. Besides using Beowulf builder to install cluster, user can later use this software to customize cluster configuration as well. Web interface has been partly supported but not complete yet.5.1 KSIX Cluster MiddlewareKSIX is user level software, no kernel modification are required to run KSIX. This feature allows for easy installation and high portability. KSIX is start by a bootstrapping utility called kxboot and stop with a utility called kxhalt. After KSIX are loaded, applications enroll into KSIX environment by calling a function cpi_init() (CPI comes from Cluster Programming Interface). In the following subsection, services offered by KSIX are explained.5.2 Global Process SpaceKSIX application can use KSIX to spawn a new task, which is distributed among nodes in the cluster. KSIX uses an automatic scheduling policy to select the target nodes. The policy module is open to the modification in the future. KSIX also allocates a set of global process ID and process group for these tasks. The id is used for task identification in the subsequent call. There are 3 modes of task supported.• Normal Mode: Task acts the same as a normal Unix task.• Restart Mode: KSIX will automatically restart this task on the same node when task terminated.• Migration Mode: KSIX start the task on different node when task termination is detected.KSIX process control APIs support the sending of UNIX signal, getting process information and more. These APIs are summarized in Table 1.5.3 Naming ServicesIn KSIX, processes can locate each other through naming service. The naming service APIs are as shown in table 2. With this service, a server process can register to a logical service name. Then, client process can bind with server using this logical services name. This allows the service server to be restarted or migrated to other node without any disruption of the service. Using this feature, we has built a feature called Fault-Tolerance RPC as shown in table 3. This feature can be used to link between stateless server and client and provides a basic level of high-availability.Table 1: KSIX Process Management APIs.API Description int cpi_spawn( char *task, int flag, char *where, int ntask, int*tid, int *gid, int pclass)Spawning tasksint cpi_spawnIO( char *task, int flag, char *where, int ntask, int *tid, int *gid, char *output, char *error, int pclass)Spawning tasks with specific location of outputint cpi_waitpid(int pid, int *status, int timeout) Wait for process terminationint cpi_setpmode(int pid, int mode) Change class of processint cpi_setgmode(int gid, int mode) Change class group of processint cpi_pkill(int pid, int signal) Send signal to process int cpi_gkill(int gid, int signal) Send signal to processint cpi_allps(KxProcStat *result) Report process status of all processint cpi_userps(KxProcStat *result) Report process status of user processTable 2: Naming Services APIs.API Descriptionint cpi_ds_reg(int, char *, struct servinfo, int *) Register server with naming serviceint cpi_ds_unreg(int, char *, int, int) Unregister server with naming serviceint cpi_ds_getinfo(int, char * ,struct servinfo, structreturninfo **)Query information of serverint cpi_ds_free(struct returninfo *) Free dynamic memoryTable 3:Fault Tolerant RPC APIs.API DescriptionKxFD *cpi_FRPC_cinit(char *service_name) Initialize clientKxFD *cpi_FRPC_sinit(char *service_name) Initialize serverKxFD *cpi_FRPC_accept(KxFD *cpifd) Accept a connection on a socket void cpi_FRPC_close(KxFD *cpifd) Close a socket descriptorint cpi_FRPC_send(KxFD *cpifd, void *buf, int size) Send a messageint cpi_FRPC_recv(KxFD *cpifd, void *buf, int size) Receive a message size5.4 Event ServicesDistributed event notification and delivery is crucial part for the implementation of many high level services including High Availability services. KSIX alsosupport event delivering between processes. Process can bind itself to named event. As the event is invoked or trigged by any process on any node. KSIX will reliably deliver the notification to the registered event owner. The APIs are as shown in table 4Table 4: Event Services APIs.API Descriptionint cpi_em_reg ( int, void *, struct servinfo, int *)Register event handlerint cpi_em_unreg ( int, void *, int, int ) Unregister event handlerint cpi_em_raise ( int, char *, struct servinfo, char*, int, struct answer **, int )Raise eventint cpi_em_read ( int *, char *, int, int *, struct timeval ) Event handler read message from event manager or raw TCP/IPint cpi_em_write ( int, char *, int ) Event handler write message to event manager5.5 Ensemble ManagementFor large cluster, system software, tools and application must be acknowledge about the change in cluster topology. KSIX subsystem that responsible for this task are called ensemble management. KSIX delete mal-function node from the ensemble automatically system it has been detected. KSIX also automatic add a new node to ensemble after the bootup process. The APIs for this class of service are illustrated in table 5.Table 5: Ensemble Management APIs.API Descriptionint cpi_addhost(char *hostname) Add host to KSIX systemint cpi_delhost(char *hostname) Delete host from KSIX systemint cpi_gethostbyrank(int rank, char *result) Convert rank to hostnameint *cpi_getrankbyhost(char *hostname) Convert hostname to rankint cpi_getallhost(KxHostInfo *hostinfo) Get array of hostname sort by rankThe following subsection gives some ideas about the application of KSIX in improving cluster environment. This support will be added in SCE in the near feature.5.6 KSIX Support for Scalable Unix ToolsIn cluster environment, the capability to issues a command to execute on every node and collect the results back is very important. User usually rely on rsh and ssh mechanism for remote command execution. But these command lack thefeature of collective operations. Hence, the execution is slow and not very scalable for large system. There is an effort to define a parallel extension to Unix command by parallel tool consortium. This SUT (Scalable Unix Tools)[12] effort is well explained in the literature. Currently, our tool, SCMS support an implementation of SUT in a form of shell script that rely on rsh for remote execution. Using KSIX fast and collective process management, a powerful SUT implementation can be done by replacing rsh with KSIX based remote execution command. Remote process can be started simultaneously on the remote machines to execute local Unix command. Then KXIO can be used to relay back the result efficiently.5.7 KSIX Support for MPI2 ImplementationKSIX dynamic process management are designed such that process creation, process termination, process group, and signal delivery can be extended to support dynamic process management of MPI-2 standard with ease. MPI_COMM_SPAWN can be mapped to KSIX spawn. Process in KSIX always form into a group or context, this can easily be mapped to context-based concept of communicator in MPI. Parent and child group can be create by first create KSIX group, then using KX_Spawn to create child group. Group id and intercommunicator can be build and keep track later. Finally, efficient dynamic process creation and control provided by KSIX can be mapped directly to MPI2 approach and help ease the development effort greatly.6 SCMS Cluster Management SystemSCMS is a main tool that will be seen in SCE. SCMS is divided into 2 layers as illustrated in Figure 7.Figure 7 SCMS ArchitectureSCMS lower layer is a set of daemon subsystems and utilities written in C, C++, and Python script language. This layer consists of:• Scalable Unix tool: A parallel implementation of frequently used Unix commands that follows the guideline given by Parallel Tool Consortium.•SCMS/KCAP Script which is a set of script written mostly in Python and Shell script. These scripts help perform many administrative task in the system. • SCMS/RMS, a fast, scalable real-time monitoring and a set of powerfulAPI in C, C++, Java, and Python that user can use to develop monitoringapplication. These API are as shown in Table 6 and Table 2.Table 6: RMI API for C language RMI API Descriptionint rmi_init(char *addr,int port); Establish the connectionint rmi_finalize(int sd);Close connection int rmi_get_node(int sd,rmi_node_struct *nodes, int max); Retrieve node name and nodeid of all alive nodesint rmi_get_nodeid(int sd,rmi_int_struct *hid); Retrieve node id of all alivenodesint rmi_get_async(int sd,rmi_int_struct *hid, rmi_int_struct *pid,char *opt, char *buf,int max); Retrieve objects in particularnodes to the buffer using asynchronous modeint rmi_get_sync(int sd,rmi_int_struct *hid, rmi_int_struct *pid,char *opt, char *buf,int max); Retrieve objects in particularsnodes to the buffer usingsynchronous nodeint rmi_set(int sd,rmi_int_struct *hid, char *key,char *value); Set internal variable "key" to"value"int rmi_load_plugin(int sd,rmi_int_struct *hid, char *plugin);Load plugin on specified nodeint rmi_unload_plugin(int sd,rmi_int_struct *hid, char *plugin); Unload plugin on specified nodeint rmi_int_init(rmi_int_struct *lst,int max); Allocate resource vectorint rmi_int_finalize(rmi_int_struct *lst); Free resource vectorint rmi_int_add(rmi_int_struct *lst,int i); Add to resource vectorint rmi_int_pack(rmi_int_struct *lst,char *buf, int max);Pack list of integer to a stringThe upper layer of SCMS consists of 2 main tools. SCMS and KCAP. SCMS is a GUI application based on Python and Tkinter. SCMS enable user to navigate, manage, monitor, and control the operation of Beowulf cluster from a single point. Some unique features of SCMS are:• Interface to SCMS/RMS real-time monitoring• Cluster Configuration collector and browser• Control command that allows system administrator to shutdown, rebootany node or set of nodes.• Innovative user interface in 3D grid format that allows user tomanipulate thousands node cluster.Some of the screen shot from SCMS are illustrated in Figure 7.Figure 8: SCMS Screenshot showing (a) Host Selector (b) Real-time Monitoring (c) Heart Beat Checking (d) Configuration BrowserSCE also offers a web base monitoring package called KCAP that allows system administrator to check monitor system remotely,. Many most of the monitoring function appears in SCMS also available in KCAP as well. Also, KCAP can help keep log of system performance, and perform cluster walk-in visualization using VRML and java based technology. Examples of KCAP user interface and cluster visualization are as shown in Figure 9.Figure 9: KCAP Screen shot showing the main menu, file system , 3D visualization of cluster nodes and file system in one node7 SQMS Batch schedulingOne of the most important components in cluster software tool is a batch scheduler. Batch scheduler received user request for program execution, select optimum set of nodes, sending a job to run, and finally, collect the result back. There are many well-known batch schedulers such as OpenPBS [13], DQS [14]. Although very powerful, these schedulers are usually very complex to install, use, and maintain. SCE try to solve this problem by giving the scientists a simple but workable scheduler called SQMS. For more intricate requirement, user can also install more complicated scheduler such as OpenPBS for their use.High-light of some features offered by SQMS are:• Support both sequential and MPI based parallel program• Provides command line to submit job, query queue status, and delete jobs.• Move result into user home file system• Support multiple form of reporting result such as email and ICQ users.• Round robin, node• Allows users to add new task scheduler• Provides C/C++ API for user to develop complex load balancing policy if required.Figure 10: SQMS Screen Shot (a)listing the queue (b) result reportedthrough mail or ICQThese functions are enough to allow multiple users to submit jobs to the system. For more detail features comparison, please refer to Table 3. From Table 3, it seems that SQMS have much less feature than OpenPBS. This is due to the focus of the development that aims more toward the integration of software in this version. Moreover, the emphasis is to develop a simple and easy to use batch scheduler. So, many of OpenPBS features are ignore since it increase a learning time of the user and, in many cases, some of these features are hardly used.8 Current Status of SCECurrent version of SCE, SCE alpha 1.0, is now available for early download at http://smile.cpe.ku.ac.th/sce . This version of SCE is intended to be a test version that developers can gain and early experience and feedback to SCE developmentteam. Beowulf Builder is still not fully function since there is an ongoing work on a new version of builder tool that is much more powerful. According to the internal schedule, SCE 1.0 Beta1, which is more stable, will be released in June.9 Conclusion and Future DirectionIn this paper, SCE, a fully integrated Software Tool for Beowulf cluster has been partly described. SCE is a rapidly evolving and long-term project. The goal is to deliver a simple but high quality cluster environment for engineers and scientists who use Beowulf cluster to do their work. Many software in SCE is the results of more than 5 years of our software tool research effort.SCE is a very active and long-term research program. There are many works that is being done now to improve SCE. First, SQMS team is now working quickly on improving SQMS in many ways. The focus will be on better support of parallel task, better scheduler, and more supporting tool that enhance system usability. Moreover, There is a new project called SCENIC (SCE on Network of Interconnected Clusters) that is investigating the addition of grid like capability so that all SCE based cluster to exchange computational task seamlessly.For KSIX, there are many related projects to enhance its capability. For example, AMATA project that is now exploring the High availability support in middleware layer, SCK project currently produce kernel level checkpointing so KSIX2 which is due next year will start to partially have checkpointing support and process migration. Better integration with MPICH will be added into SCE. There is now a work on using KSIX, KXIO, and SCMS/RMS to build a debugger and runtime visualization software for MPICH.
