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
