Anybody reaserched the best values for highly multithreaded apps like engineering applications running single application with large (>64 GB) core needs. This slightly different segment than strickly server system

For $2,500 or so you could likely build a 2P server with a pair of AMD Opteron Interlogos 16-core CPUs, but it depends on how you want to populate those DIMM slots. To fully enable quad-channel I believe it would require 8 sticks BUT if your instances are not memory intensive you could cut back to the bare minimum, there.

A 4P build around $5k is doable -- the mobo, CPUs & RAMs would run you just short of $4k (with 16x2GB sticks). That will get you 64 cores.

There are no more 'modern' Opteron 8P systems, so 4P it is.

It may well be that youre correct Wisecracker. Maybe x86 may be the most significant bottleneck in the whole equation. The main issue at present is that some applications that we need are not ported to linux although they are highly multithreaded
