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