  3. Proof-of-Concept Mission The VL-e Proof-of-Concept (PoC) • is a shared, common environment, • where different tools and services are • both used and provided by the VL-e community Two key branches • PoC Software Distribution • PoC Infrastructure Service and Service Hosting

  4. PoC Architecture High-Level overview • Many different tools and services • From many different providers • Tied together in a common framework Service-Oriented Architecture (SOA) • Re-useable software components • Integrated at the work-flow layer technical implementation details still remain …

  5. Data Intensive Science Food Informatics Medical Imaging Biodiversity Bioinformatics Dutella P1 P2 P3 P4 Adaptive Information Disclosure WorkFlow InformationManagemt Visuali-sation Problem Solving Env. Grid, Globus, SRB, WS, IBIS Infrastructure Managing the PoC: VLeIT • VL-e Integration Team • collects and prioritizes • organizes the development effort • decides on tools that are part of the PoC

  6. VLeIT members

  7. VLeIT operational model • Collection of usage scenarios • Identification of generic elements & commonality • Matching tools with applications • Prioritizing development effort • Managing pool of scientific programmers • Advise the user scenario working groups(process currently being implemented)

  8. Usage Scenarios Working Groups • Currently being started, some already operational • For example: • BioInformatics (with AdamB, PaulvH) • Food (with MachielJ) • Dutella (with PaulvH) • IBED (with PaulvH) • … • …

  9. Building the PoC: Scaling and Validation • Build • Software Layers • Certification & Deployment Process • What might be there? • Support

  10. The shared PoC infra and software • physical infrastructure (such as computers, storage, …), • central services (database hosting, repository services, …), • the PoCsoftware suite. For convenience, the following elements of this suite can be distinguished: • Grid foundation middleware; the basic software that is based on interfaces and concepts that are globally adopted and standardized. This includes elements such as the security model, resource allocation interface, … • Generic Virtual Laboratory software (‘P2’); the software developed within the project for the PoC. • Services imported from outside; given that not all services are necessarily developed within VL-e, some will be imported. • Associated installation and deployment tools; the PoC suite is installed on the central facilities and (where applicable) also available for distributed installation.

  12. Release management and stability • Foundation middleware: ‘timeboxed’ releases • Next release January 2006

  13. Release management and flexibility • Application can build on top of stable foundations in the PoC • Installation of application software on both central and distributed infrastructure • Rapid upgrades at the user’s discretion • Installation support for application-level ‘software managers’ on the central systems

  14. Proposed base tools for distribution R1 VLeIT document forthcoming, pending approval …

  15. Proposed base tools for distribution R1 VLeIT document forthcoming, pending approval …

  16. Specific Installations on the PoC • Some specialized software installed on designated central facilities (‘Matrix’): • VLAM • SRB server • NIMROD Portal

  17. Support and training • Next PoC release:January 2006(code cooled: Oct 1st 2005) • GANG “Admin Nerd Group” in mid-January • Application-development oriented event mid-February • User help-desk for the PoC (020) 592 8008, grid.support@sara.nl
