Dual cpu single core, opteron. Make sure that the 1G of RAM are enough for your application. Also consider a low latency interconnect, i.e. infiniband because I have seen cases where CFD exchanges a lot of small messages.

I've heard many times that memory throughput is extremally important in CFD and that using of 1 cpu/1 core per node (or 2 single cores Opteron having independed memory channels) is in some cases better than any sharing of memory bus(es).
