[gmx-users] Re: [gmx-developers] installing the parallel version of Gromacs 3.3.1

[Alexey Shvetsov]

Hi all!

There also another problem. You are using intel compilers on amd based 
machine. Intel compilers uses cpuid to identify processor and optimization and 
they doesnt include amd cpuids at all. So you will have bad performance on amd 
cpus. I'd recomend to use recent versions of gcc (gcc-4.5+) and math libs like 
atlas or gotoblas2 for blas and lapack. This combination will perform much 
better then icc
