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

  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) GigaPort Leiden (32) Delft (32) Utrecht (32) 200 SMP nodes (IBM xSeries) with two 1GHz Pentium-IIIs,  1 Gbyte memory

  7. 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) Systems research in ASCI

  8. 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) Applications research in ASCI

  9. DAS-2 Application performance • Case study: endgame databases for Awari • 1995 (Bal & Allis, Supercomputing’95): • Computed database with 5 108 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  1012 entries) ….
