[Beowulf] Performance of Intel vs AMD compute nodes

[Achilles Vassilicos]

Hello list,

This topic has probably been discussed before.  Still, I would like to hear
some opinions/input about these specific issues.  In terms of expected
performance, what is known about the following CPU choices.

Field of work: CFD
CPU: Intel 5160 or 5365 (3.0 GHZ) vs. AMD 2222 or 8222 (3.0 GHZ)
Network: Gigabit Ethernet
Sockets: 2 per MOBO (there are also some 4-socket MOBO choices)
Memory: 8 (for dual-core chips) or 4 GB (for quad-core chips) per core

Thanks in advance,
Achilles
