  3. DAS - II • ASCI-onderzoeksschool • Leiden, Delft, UVA, VU, (Utrecht) • Utrecht in DAS-I voor Netwerken (ATM), nu volwaardig • DAS-II NWO subsidie • (project totaal 2 Mfl, 75%) • 5 clusters of computers

  4. Configuratie • IBM, Rack based, basic 32 nodes xSeries 330 • Server • Pentium - III • Dual processor • 1 Gigahertz • 2 PCI slots, 33 Mhz, 64 bits slots, full + half size • Myrinet-II • 100 Mbit Ethernet • Extreme 48-I switch/router • 48 * 100 + 2 * 1000 Gbit/s

  5. DAS-II test Data Grid DAS-node MYRINET L3/4 Switch router storage SURFnet/5 1 Gbit/s Compile Data

  6. Data Grid Test facility • Features • 1 Gbit/s uplinks to national backbone • Non blocking access to other DAS nodes • Computing and networking speed same order of magnitude • Location of data visualization and computing independent • 4 layers of inter-process communication • Shared memory • Myrilink (2 Gbit/s) in user space • 100 Mbit/s and Gbit/s locally switched Ethernet (kernel space) • 1 Gbit/s routed Internet connectivity (kernel space) • Many unique research degrees of freedom • Infrastructure requirements • Heavy switches/routers for 1 Gbit/s uplink capability • 1 Gbit/s Ethernet interface for uplink • Private fibers to NRN backbone ?
