Ali,
You might want to consider looking into Tyan's VX50 systems, that
system is able to handle dual core Opterons (8*2=16 cores, it does not
support the 9000 series quad core though) and it can go up to 128Gig of
RAM. Some advantages are:
Each Opteron chip (datasheets:

I have found that PGI does great on dynamic arrays, but poorly on
static. Alas the inverse is true for pathscale, great on static
arrays but poorly on dynamic.

If this is indeed the case for your problems then you might find that
quad core systems don't cut it - a contact

- high per-CPU memory performance. Each CPU (core in dual core
systems) needs to have its own memory bandwith of roughly 2 or more
gigabytes. For example, standard dual processor "PC's" will
notprovide better performance when the second processor is used, that
is, you
will not see speed-up

I got an advice that because the prices of Xeon Quadcore is going to

Ideally you would plan on buying $x of cluster instead of limiting your
choices to a particular number of PCs. There are 1,2,4 socket machin
