Flexibility and user-friendliness of grid portals: the PROGRESS approachMichal Kosiedowski, Cezary MazurekPoznan Supercomputing and Networking Center, ul. Noskowskiego 10, 61-704 Poznan, Poland{kat, mazurek}@man.poznan.pl1. IntroductionThe PROGRESS project [1] started in the end of 2001 as a grant from the Polish Committee of Scientific Research co-financed by Sun Microsystems. It aimed to design and implement an access environment to computational services performed by a cluster of Sun servers [2]. The grant, which finished in 2004 with the deployment of the PROGRESS HPC Portal [3], produced a set of grid-portal tools that were released under an open source license. These tools, advertised as the PROGRESS Package, allow to deploy a flexible grid access environment in various configurations ranging from a local area computing portal, through a campus solution to an inter-campus-wide system.In this paper we show how the results of the PROGRESS project may be used to deliver grid portal solutions and how they facilitate the construction, management and use of a grid portal. First, in section 2 we shortly review the novel architecture for a grid-portal environment that was designed by the project. Then, in section 3 we discuss the advantages that are brought by the approach that we assumed in PROGRESS. In section 4 we describe the reference installation of the PROGRESS Package and the type of grid applications enabled in this environment. We end with a short summary in section 5.2. ArchitectureFigure 1 presents the PROGRESS approach to the grid-portal environment architecture. In this approach, apart from a classical grid management system enabled through a grid resource broker, we introduce the Grid Service Provider which acts as an additional layer between the actual user interfaces, such as, for example, portals and the grid. The Grid Service Provider features high-level grid services which facilitate the construction of grid portals and access to the computing resources [4, 5]. The whole computing environment is assisted by the Data Management System capable of storing large amounts of scientific data [5, 6].Figure 1 PROGRESS approach to a grid-portal environmentThe Grid Service Provider groups several high-level grid services enabled through Web Services access interfaces. These services manage abstractive descriptors for various types of grid objects such as, for example, computing jobs or computing applications, and store them in an underlying database. Two most important services are the Job Submission Service and the Application Management Service:o The Job Submission Service delivers functions for computing job building, submitting them to the grid for execution and viewing the results. It allows to create jobs, configure its tasks and set the requirements for grid environment resources. The service prepares grid job descriptions using a job description language which is then transferred to a grid resource broker for the execution. The Job Submission Service features the grid resource broker plug-in mechanism which allows it to cooperate with several independent grid infrastructures.o The Application Management Service manages the PROGRESS application repository. An application descriptor contains a reference to the application’s executable and a set of its available, required or optional arguments, required environment variables as well as input and output files. One executable may be referenced by many applications, and different application configurations are viewed as independent applications.The Data Management System is a distributed environment which allows access to large amounts of scientific data and allows to store the data on different types of storage media such as, for example, generic filesystems, archiving systems or relational databases. It also features a specialized module which allows read-only access to external scientific databanks, such as for example gene banks [7]. The whole functionality of the system is available via the Data Broker which is a Web Service. The data transmission can be performed with the use of several protocols including FTP, GASS and GridFTP.The services provided by the Grid Service Provider, the Data Management System, and thus the underlying computing and data grid resources can be enabled within web portals through a set of Java portlets. The available PROGRESS Portlets include several core portlets, whose aim is to deliver the whole functionality of the Grid Service Provider and of the Data Management System, and some specialized application portlets, whose aim to provide an easy-to-use interface to grid-enabled applications. The portlets were created with the use of the PROGRESS Portlet Framework, which is a platform allowing to facilitate the process of building user interfaces to remote Web Services.3. PROGRESS Approach AdvantagesWhen comparing the PROGRESS approach to other grid portal solutions, the biggest similarities can be found with GridPort [8]. Both these systems seek to orchestrate lower-level services into more sophisticated services at a higher level of granularity and aim to provide a single, integrated, high-level API spanning a comprehensive set of low-level grid services. PROGRESS and GridPort both offer a set of Web Services, which not only serve as a remote single-point of grid access, but also feature means of storing and managing various types of grid objects such as, for example, computing jobs.PROGRESS and GridPort are examples of a novel approach to the organization of access to grid resources and services as compared to such solutions as, for example, GridSphere [9]. GridSphere, which, on the other hand, is an excellent piece of work, is more directed towards delivering an efficient and flexible portal framework with a set of some basic grid portlets, than towards providing a complex access environment. It supports the newest portlet standards including JSR 168, which allows the reusage of those portlets that are already implemented within multiple portal instances, not necessarily built on top of GridSphere. It, however, does not directly support high-level aggregation and management of lower-level grid services.Both GridPort and GridSphere are examples of good, functional and widely used grid portal platforms. However, our approach, which seeks to find itself among the best solutions, adds some new mechanisms to improve the flexibility of a grid portal even more. In particular, these mechanisms include the PROGRESS Portlet Framework which offerscapabilities facilitating the construction of application portlets [10], and the grid resource broker plug-in mechanism included into the Job Submission Service, which allows a grid portal to seamlessly cooperate with multiple independent grid installations.The PROGRESS Portlet Framework is a platform that enables developers to easily and quickly build new portlets accessing Web Services. The component architecture of the Framework, presented in Figure 2, allows to efficiently reuse parts of the already existing code during the construction of a new grid portlet. The platform also offers a possibility to easily change the behavior and functionality of an already existing portlet to suit the particular portal needs by playing with XML-based portlet configuration files. These features are especially useful in the process of enabling new applications on the grid. A scientist familiar with the Framework structure and capable of Java programming can create a new specialized application portlet within a week. Such a portlet is familiar with the corresponding application structure and delivers an application user interface which allows a scientist unfamiliar with the grid to create and submit a new grid job within a few mouse clicks and without any grid knowledge.Figure 2 The component architecture of the PROGRESS Portlet Framework The grid resource broker plug-in mechanism is designed to provide the grid portal users with a possibility of submitting the same grid job to resources belonging to different independent grid infrastructures. A grid resource broker plug-in is a Java class, with some additional required libraries, which implements a special API that allows the Job Submission Service to use it to contact the actual job submission engine. Each of the available plug-ins, which are described within the Job Submission Service’s database, can be used to connect to any number of job submission engines with which the plug-in can communicate. The job submission engines are also described within the service’s database, giving the user a possibility to choose the grid infrastructure he/she wishes to submit his/her job to. In this way the Job Submission Service and thus any grid portal utilizing this service gives users an opportunity to utilize various computing resources to which users have access from the same grid portal.4. PROGRESS HPC PortalThe advantages of the PROGRESS approach at the grid-portal environment architecture are widely utilized by the reference installation of the PROGRESS Package. In this installation, namely in the PROGRESS HPC Portal, several applications are enabled on the grid through specialized application portlets. These applications include bioinformatic DNA Assembly [11] and chemical Gaussian and Gamess. Apart from being enabled via specialized application portlets, these applications together with a few other are also available within the core “My computing jobs” portlet. A PROGRESS HPC Portal screenshot is presented in Figure 3.Figure 3 PROGRESS HPC PortalA specially interesting portlet is the portlet prepared to facilitate the use of the DNA Assembly application developed by Prof. Jacek Blazewicz’s group at the Institute of Computing Science of the Poznan University of Technology (PUT). It not only allows to quickly build new jobs with the use of an intuitive job construction wizard, but also automatically builds workflows if necessary. An interesting portlet has also been prepared for another bioinformatic application. This application, which finds aminoacid sequences similarity, compares thousands of input sequences, at least some of which may be generally known and available within sequence banks. The portlet, which is set to enable the application within the portal, allows the users to search for these known sequences within the SRS System banks [12] enabled as read-only data within the Data Management System instance with the use of the specialized proxy module mentioned in section 2. The found sequences may then be used, together with any other sequences, as the input for the job performed on the grid. The aminoacid sequences similarity application is currently under development at PUT; it will soon be deployed onto the PROGRESS grid together with the corresponding portlet in the near future.Together with all the various portlets available within the portal, the PROGRESS HPC Portal users will soon be able to utilize the resources of two separate grid infrastructures. At the time of writing a grid resource broker plug-in for the Grid(Lab) Resource Management System [13] is under development. This will allow the PROGRESS HPC Portal users to gain access to the GridLab testbed resources in addition to the regular PROGRESS grid. Provided that a user holds a certificate allowing him/her to successfully authenticate on a GridLab resource, he/she will have an opportunity to utilize a wider set of computing resources.5. SummaryIn this paper we presented the PROGRESS grid-portal tools and their advantages in comparison with two commonly known and excellent grid portal solutions. It is important to note that GridPort and GridSphere are only examples, probably those most popular, of the work being done by the grid community in the area of grid portals construction. These two and all others are solutions that we find as those that can provide a view at best practices used around the world. Such best practices should, however, strongly take into consideration the need for the simplicity of grid portal management and use. With the PROGRESS approach at the grid portal construction and with such mechanisms as those provided by the PROGRESS Portlet Framework and grid resource broker plug-ins, we aim to contribute to the facilitation of the grid portal construction and maintenance process.The PROGRESS grid-portal tools were successfully deployed as the PROGRESS HPCPortal with several grid applications enabled through specialized user interfaces. This portalenvironment is aiming to expose all the functionality provided by the PROGRESS Package tools. It is, however, one of the grid-portal environment configuration examples that could be achieved with the use of the PROGRESS Package. The PROGRESS tools can be deployed in many different configurations, starting with simple local infrastructures, through campus installations to more complex systems on an inter-campus level. Some of such grid-portal environments are the subject of our joint with Sun Microsystems offers in several locations around the world. The PROGRESS Package is also under investigation as to its suitability for a few other grid portals. In all these cases one of the most important features underlined by the end users is the need for flexibility and user-friendliness. These goals are some of the main drivers of the work we are doing in the field of grid portal tools design.References1. PROGRESS project website. http://progress.psnc.pl/2.
