Hi,

I want to build an hpc cluster for running mm5 and wien2k
scientific applications for my physics coledge. both of them
use MPI.

Interconnection between nodes: GigEth (Cisco 24 port GigEth)

It seems I have two choices for nodes:
 * 32 dual core opteron processors (1 GB ram for each node)
 * 64 single core opteron processors (2 GB ram for each node)

Which is better (performance & price)?
