[mpich-discuss] choosing processors for MPI and MPICH apps

[zach]

Is there any kind of general guidelines to use when choosing multicore
processors for machines you intend to run parallelized mpich applications
on? in terms of architecture, cache size, memory bandwidth, etc

for example i found a dual processor quad core intel xeon E5506 server box
for a decent price. would this system be able to scale towards at least 7x
with MPI? How can I tell before buying something and trying it?
