The Alpha cluster, comprising of eight 500MHz 21164 PCs connected by fast Ethernet shows poor scalability past 4 processors. The Pentium II-300 cluster using Myrinet shows much better scaling than with the slower network. It actually approaches the Origin 2000 out to 12 nodes. The run time on 12 nodes was 681s on the PII-300 cluster versus 471s on the Origin 2000. Return to top of page Hosted by with support from Page last updated 20 Apr 2001 .
