Open Science Grid

1. Open Science Grid MWSG-2 17 June 2004 Bob Cowles bob.cowles@slac.stanford.edu

2. Open Science Grid • Open Science Grid is the consortium (not a project) in the US for ensuring all of our Grid efforts, including and in particular the LHC ones, come together towards a coherent and sustained Grid infrastructure that • Provides computing for LHC science – US contribution to LCG but is open to other experiments and other sciences • Will work with, collaborate and interoperate with the Grid infrastructure provided through EGEE • Open Science Grid “Technical Groups” scope explicitly includes cooperation with the EGEE/LCG peers groups. Open Science Grid - MWSG2

3. Open Science Grid - a Consortium • Commitment of participants to align existing and future work. • US LHC computing and research programs contributing to Open Science Grid deliverables • Will look for incremental funding to get “added value” from coherence and enable system engineering • Ensure longevity of the middleware technologies to match the lifecycle of the experiment Open Science Grid - MWSG2

4. Towards a coherent sustained production Grid infrastructure • A 5-10 year roadmap to match life-cycle of Particle Physics Experiments committed to Grids for Data Analysis. • Start from the needs of our experiments today • End-to-end approach delivering to requirements and schedule of participating application communities. • A framework for a coherent system approach through joint projects across the members. • Cooperation across DOE & NSF, Universities and Laboratories, Trillium Grid Projects - GriPhyN, iVDGL, PPDG, Middleware and Technology Groups, and Experiments Open Science Grid - MWSG2

5. EGEE- OSG Partnership L. Bauerdick, L.Robertson Open Science Grid - MWSG2

6. BaBar, Run II SAMGrid, US Testbeds, Grid3, …an evolution • Babar data distribution with GridFTP & SRB • CDF and D0 >1.5 Petabytes in mass storage at Fermilab. SAMGrid data grid developed for distributed data simulation data analysis over >25sites. • LIGO DataGrid for a coherent and uniform LIGO data analysis environment • Joint US-LHC, LIGO, SDSS and Computer Science Laboratory Grid3. • In use for US ATLAS DC2. US CMS gained 50% in overall throughput for 17Million event simulations. SDSS southern “coadd of objects” in progress. ANL GADU biology users. Computer science application demonstrators. D0 files transferred Open Science Grid - MWSG2

7. Grid3 --> OSG • Grid3 now separate Development and Operations Environments. • iVDGL will sustain a Grid Laboratory and contribute • Deploy, integrate, use new services and technologies as they evolve - data management, ARDA, WRSF services • Tests of scalability and robustness of end to end system • Demonstrate as results of computer science research and development. • PPDG extension includes contributions to OSG and a core common project • Laboratory facilities will contribute currently “parochial” storage and computing to a “shared common infrastructure” • Work towards OSG-0 for January 2005. • Include Accounting System (requirements?) • Move to a Production Environment Open Science Grid - MWSG2

8. The Model Open Science Grid - MWSG2

9. Sustaining and Hardening the Middleware • Acquire - adopt, sponsor, extend - developments and research of member technology groups and external partners. • Projects to demonstrate capabilities and robustness of the middleware • Coherent process for versioning, releases, testing distribution - evolve VDT Open Science Grid - MWSG2

10. OSG next - small - steps • OSG will provide for running particle physics experiments - BaBar, Run II, STAR - grids to come to a coherent infrastructure • Some Joint Projects identified at Trillium/S&C Management/Lab facilities Joint Steering Meeting in UofChicago in May • PPDG collaboration meeting at end of June next place for some face to face discussion. • Security & Storage Technical Groups established Open Science Grid - MWSG2

11. Technical Groups • Coordinate and communicate • Propose & oversee joint projects and subprojects related to their given areas. • Liaise and collaborate with their peer organizations in the U.S.and world-wide • Participate in relevant standards organizations. • Representatives will participate in the OSG-wide integration, & operations activities. Open Science Grid - MWSG2

12. Security Technical Group • Reports to the OSG Collaboration Board - to date a broad mail list • Evolution of PPDG SiteAA group • Bob Cowles (SLAC), Dane Skow (Fermilab), Mike Helm (ESNET), Doug Pearson (Indiana, iVDGL/iGOC), Von Welch (NCSA), Remy Evard (ANL), Tom Throwe (BNL), Doug Olson (LBNL) Open Science Grid - MWSG2

13. Security Technical Group-Mission • The Security Technical group is responsible for coordinating the OSG activities that relate to security policy, practices and services. These include: • Negotiation of common security principles and expectations for security across the Consortium. • Development and oversight of common requirements and architecture for security management across the Consortium.◦ • Identification of necessary projects and work needed for a coherent, complete Security infrastructure on the common grid. • Interoperability of Security infrastructure across different administrative domains, initially OSG and EGEE through the LCG Joint Security Group. • Publish information about security Open Science Grid - MWSG2

14. Issues on the Table to Date • “Top ten” list ++ • How to organize ourselves • acting as both “Joint Security Group” + “JRA3” • how to have an impact • first priorities • How to collaborate effectively with • Joint Security Group • JRA3 Open Science Grid - MWSG2
