Hello folks I just built up my first beowulf cluster with the latest PCI64B-2 cards (PCI64C was available just a month later our order :-(). Hosts are all DEC Alphastation 500/500 (alcor arch). OS is Linux with kernel 2.2.19. Buses are 32bits @ 33Mhz so my guess is at least a 100-130MBs of throughput. In fact, reality is well different... gm_allsize gives me a maximum bandwith of 56MBs. Any hints? PS: This is a Debian GNU/Linux cluster, not the boring RH flavor... hip, hip, hurrah for the Debian Project... -- Francesco P. Lovergine
