  1. GridLabEnabling Applications on the Grid www.gridlab.org Jarek Nabrzyski et al. naber@man.poznan.pl office@gridlab.org Poznań Supercomputing and Networking Center

  2. GridLab Project • Funded by the EU (5+ M€), January 2002 – December 2004 • Application and Testbed oriented • Cactus Code, Triana Workflow, all the other applications that want to be Grid-enabled • Main goal: to develop a Grid Application Toolkit (GAT) and set of grid services and tools...: • resource management (GRMS), • data management, • monitoring, • adaptive components, • mobile user support, • security services, • portals, • ... and test them on a real testbed with real applications Grid 2002, Baltimore, 18 November 2002

  3. GridLab Members • PSNC (Poznan) - coordination • AEI (Potsdam) • ZIB (Berlin) • Univ. of Lecce • Cardiff University • Vrije Univ. (Amsterdam) • SZTAKI (Budapest) • Masaryk Univ. (Brno) • NTUA (Athens) • Sun Microsystems • Compaq (HP) • ANL (Chicago, I. Foster) • ISI (LA, C.Kesselman) • UoWisconsin (M.

  4. GridLab Applications Cactus (www.cactuscode.org) Triana (www.triana.co.uk) Grid 2002, Baltimore, 18 November 2002

  5. GridLab Aims • Get Computational Scientists using the “Grid” and Grid services for real, everyday, production work (AEI Relativists, EU Network, Grav Wave Data Analysis, Cactus User Community), • Make it easier for applications to make flexible, efficient, robust, use of the resources available to their virtual organizations • Dream up, prototype, and test new application scenarios which make adaptive, dynamic, wild, and futuristic uses of resources. Grid 2002, Baltimore, 18 November 2002

  6. What GridLab isn’t • Don’t want to develop low level Grid Infrastructure, • Don’t want to repeat work which has already been done (want to incorporate and assimilate it … Globus APIs, OGSA, ASC Portal (GridSphere/Orbiter), GPDK, GridPort, DataGrid, GriPhyn) Grid 2002, Baltimore, 18 November 2002

  7. GridLab end user requirements • Application oriented environment, • Applications running on resources of one or more virtual organisations, • Flexible, easy-to-use, simple interfaces to resources, jobs, and data (including compiling, tracking jobs, cataloguing data), • Means to make efficient and effective use of resources, • Robustness, implying that smart adaptivity, complete control and fail safety areavailable on all levels, • The ability to work in a disconnected environment, • Mobile working Grid 2002, Baltimore, 18 November 2002

  8. GridLab end user requirements • The ability to run in environments as minimalistic as laptops with no grid infrastructure tofully deployed Virtual Organisations, • Complexity should be hidden as much as possible, • Provide a collaborative infrastructure, • The infrastructure must cater for all classes of applications, from lightweight to largescale, • The infrastructure must provide capabilities to customise choice of service implementation (e.g.using efficiency, reliability, first succeeding, all) Grid 2002, Baltimore, 18 November 2002

  9. End Users GAT-API Developers GAT Tool Developers Grid Infrastructure Developers Solution... • GAT – a layer between apps and emerging grid technologies • GridLab tesbted/VO • Close cooperation between developers and deployers Grid 2002, Baltimore, 18 November 2002

  10. The Grid is complex … Cactus “Is there a better resource I could be using?” SOAP WSDL Corba OGSA Other Monitoring Profiling Information Logging Security Notification Resource Management Application Manager Migration Data Management GLOBUS Other Grid Infrastructure? Grid 2002, Baltimore, 18 November 2002

  11. …need to make it easier to use Cactus “Is there a better resource I could be using?” GAT_FindResource( ) GAT The Grid Grid 2002, Baltimore, 18 November 2002

  12. GAT: What is It? GAT: Grid Application Toolkit • Implements the GAT-API • Used by applications (different languages) • GAT Adaptors • Connect to capabilities/services • GAT Engine • Provides the function bindings for the GAT-API Grid 2002, Baltimore, 18 November 2002

  13. Grid Application Toolkit • The GATprovides functionality through a carefully constructed set of generic high-level APIs, through which an application will be able to call the underlying gridservices, • Set of application developer APIs for Grid tools, services and software libraries, (and example implementations) that support the development of grid-enabled applications (open source!) • Usable from any high level “application” (any generic code, Cactus, Triana, Portals, Scripts, …) Grid 2002, Baltimore, 18 November 2002

  14. GAT • More or less … • Set of calls GAT_ToolOrService(arguments) • Your chosen tools/services: resource broker, information server, application manager, grid monitoring, data manager, notification, etc. • Set of APIs for dealing with the GAT (registration, information, errors, fault tolerance) Grid 2002, Baltimore, 18 November 2002

  15. GAT Engine When an application makes a GAT-API call, the engine searches through an internal database of adaptors for the requested capability and calls it Grid 2002, Baltimore, 18 November 2002

  16. GAT Adaptor • Interface between GAT Engine and one or more capabilities • Translates user requests to appropriate interface syntax for a capability provider • Active adaptors change dynamically • Includes “security context” • Return appropriate error codes • Examples • OGSA adaptor (provides many capabilities) • Globus adaptor (directly talk to gatekeepers) • Adaptors for each GridLab service provider • “Local” adaptors (GAT_MoveFile => “cp”, GATFindResource => “localhost”) Grid 2002, Baltimore, 18 November 2002

  17. GAT Adaptor Grid 2002, Baltimore, 18 November 2002

  18. GAT: AIM • Abstract Grid capabilities (services) from the application developer. • Application developer concentrates on the functionality as needed by the application. • Hide complexity. • Provides a layer (buffer zone) between applications and the Grid. Grid 2002, Baltimore, 18 November 2002

  19. The Same Application … Laptop Super Computer The Grid Application Application Application GAT GAT GAT Firewall issues! No network! Grid 2002, Baltimore, 18 November 2002

  20. GAT Architecture Grid 2002, Baltimore, 18 November 2002

  21. GridLab services • Software environment for Grid-enablingscientific applications • GridLab services, third party services and various core-grid services will be supported by GAT • In the advent of the Open Grid Service Architecture(OGSA), GridLab's architecture will revolve around the notion of services, • all the GridLab services will be OGSA compliant • currently all the services are Web Services based • roadmap for Web Services to OGSA transformation is being prepared (6-8 months from now) Grid 2002, Baltimore, 18 November 2002

  22. GridLab Testbed • Managed by Masaryk University, Czech Republic • Operational since March 2002 • Most of the machines are not dedicated, except one cluster at PSNC • Built on existing middleware: • Globus Toolkit 2.0 • MDS 2 • PKI/GSI for secure access • Provide functional Grid environment for development and testingof GATs, services and their components • Production stability a goal • No long production jobs Grid 2002, Baltimore, 18 November 2002

  23. More info / summary • www.GridLab.org • gridlab@gridlab.org, news@gridlab.org • office@gridlab.org • You’re welcome to join our testbed and test our software, • Bring your application and test it with the GAT and our services. • We are open for collaborations! • Visit us on Tuesday and see the demos at: • Sun Booth, 12.00-1.00 p.m. • Argonne Booth, 1.00 p.m – 2.30 p.m. Grid 2002, Baltimore, 18 November 2002
