Is HT really that bad compared to a specialized low latency interconnect? I'm configuring a small cluster for some people and the prices for 16 node x 4-core with Myrinet/Infiniband/Quadrics is close enough to a Tyan VX50 4 node x 16-core system also with Myrinet etc. The apps that will run are MPI based molecular dynamics and maybe some CFD code. I tried signing up at the AMD Devcenter to get access to their clusters for benchmarking but it's been weeks and still no response. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
