I recently purchased a few servers from Advanced HPC: Supermicro RM-206 servers with 4 AMD sockets (currently using 4 x 12-core at 2.3GHz) and 512GB (yes, 0.5TB) memory. Heck of a machine for about the same price we paid for a Dell 905 a couple years ago. While not your typical "cluster node", the 48 CPU cores and huge memory are a big win for "piggy" applications. Obviously, you can bottleneck on the network connection or the local disks, but if the app can fit on a single machine, rather than having to be split across several, it can be a win. --- Cris -- Cristopher J.
