For new projects, you may want to consider IB as the costs have come down. See this:
http://www.clustermonkey.net//content/view/222/2/ I have some performance numbers for these cards (back to back) and they work quite well for the price ($125). I'll be posing some data soon (4 us latency and 5000 Mbits/sec using OpenMPI and netpipe) Of course, for the real cheapskates (like me) there is always the PT 1000 "desktop" (~$50) adapter (1X PCIe). Using TCP netpipe I see 27-30 us latency and 850 Mbits/sec But as the core counts on the motherboards get higher, IB gets more attractive. I'm playing with open-mx on these adapters and I get about 12us netpipe MPI latency. -- Doug > Hello, Beowulf list. > > I've been using 3COM 3C2000 Gigabit NIC's in our Beowulf cluster since I > built it.
