Unfortuntately, we're not a beta. I read a case study somewhere, which I can't find now. I believe that within a single node, it's crossbar, and between nodes in a cluster they use Quadrics Supercomputer World, Ltd. (QSW) derived technology. http://www.compaq.com/hpc/systems/sys_sc.html Currently, you can order nodes with 32 CPU's and next year 64. There is at least one beta site that has 64 nodes up and running, because I did read a case study somewhere.
