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

Applications research in ASCI

• Virtual laboratories (VL)
• Image processing (PILE)
• Weather forecasting (Hirlam)
• Search in large image databases
• Ubiquitous communications (UBICOM)

DAS-2 Application performance

• Case study endgame databases for Awari
• 1995 (Bal Allis, Supercomputing95)
• 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) .
