2 10.00 - 11.00 -Onno Boxma (NWO-GBE, Eindhoven Univ. of Technology) Opening -Ian Foster (Argonne National Laboratory) Open Grid Services Architecture 11.30 - 11.40 Henri Bal (VU) - Introduction DAS-2 11.40 - 12.00 John Romein (VU) - Retrograde analysis 12.00 - 12.30 Dick Epema (Delft) - Processor co-allocation 13.45 - 14.30 Daron Green (IBM) - IBM and Grid computing 14.30 - 15.00 Adam Belloum (Amsterdam) - Virtual laboratories 15.30 - 16.00 Herbert Bos & Lex Wolters (Leiden) - Education 16.00 - 16.30 Aad van der Steen (Utrecht) - Distributed data assimilation Program

3 Distributed ASCI Supercomputer 2 (DAS-2) Henri Bal Vrije Universiteit Amsterdam Faculty of Sciences

4 Distributed ASCI Supercomputer (1) Shared testbed for research on parallel and distributed computing -Set up by ASCI research school in 1997 -Geographically distributed cluster-based system -4 clusters with 200 nodes in total -Homogeneous (same processors, network, OS) Opening workshop: 2 March 1998 -Carl Kesselman, Andrew Grimshaw

5 Second testbed: DAS-2 ASCI obtained funding from N.W.O. in June 2000 ASCI committee to do detailed design and selection -Henri Bal, Bob Hertzberger, Henk Sips, Lex Wolters, Aad van der Steen, Cees de Laat Decisions -Homogeneous architecture -Nodes: dual Pentium-IIIs (SMPs) -Network: Myrinet + Ethernet (OS) -OS (Linux) -Vendor (IBM), configuration, …. Installation by IBM: November 2001

6 DAS-2 VU (72)Amsterdam (32) Leiden (32) Delft (32) GigaPort Utrecht (32) 200 SMP nodes (IBM xSeries) with two 1GHz Pentium-IIIs,  1 Gbyte memory

7 Systems research in ASCI Distributed supercomputing (Albatross) Mapping data-parallel programs (AUTOMAP) Compilers for distributed/embedded systems (JOSES) High-performance Java (Manta) Middleware for scalable wide-area applications (Globe) Distributed web caching Dynamic task migration (Dynamite) Resource management in wide-area systems Quality of Service Authentication, Authorization, and Accounting (AAA)

8 Applications research in ASCI Virtual laboratories (VL) Image processing (PILE) Weather forecasting (Hirlam) Search in large image databases Ubiquitous communications (UBICOM) N-body simulations (GRAPE) Web servers Autonomous interacting robots (AIR)

9 DAS-2 Application performance Case study: endgame databases for Awari 1995 (Bal & Allis, Supercomputing’95): -Computed database with 5  10 8 entries on 80-node MicroSparc cluster (predecessor of DAS-1) 2002 (Romein & Bal): -See how far we get on DAS-2 towards solving the entire game (9  10 12 entries) ….
