I recently ran a customer's weather modeling code on a variety of
machines. This program is very sensitive to memory. The following are
the run times while running 4 processes. Please note that the Xeon,
Opteron and Barcelona numbers are from dual socket machines.

Core 2 Quad 2.4 GHz - 3h16m
Xeon Quad 2.0 GHz - 2h51m
Barcelona 2.0 GHz - 1h40m
Opteron 2220SE 2.8 GHz - 2h24m

At 8 processes:

Xeon Quad 2.0 GHz - 2h52m
Barcelona 2.0 GHz - 1h22m

and a dog, and a fireplace and maybe enough money to give myself some
Irish coffee now and then and entertain my two friends.
