Will you be able to compare this against Intel's Math Kernel Library or AMD's Core Math Library
Well, I don't think those libraries provide such kind of a facility. I thought MKL was Intel's LAPACK homebrew ?
Both libraries provide at least a subset of the functionality in your benchmarks. http://www.intel.com/cd/software/products/asmo-na/eng/266863.htm http://developer.amd.com/cpu/Libraries/acml/downloads/pages/default.aspx#doc... (use the "ACML User Guide/FFT Documentation" link which goes to a pdf)
I guess I can install some of this (at least Intel as I don't have AMD machine overthere) and see what can be compared in a proper fashion.
ACML works on Intel processors as well, but is not optimal.
Currently, a GEMM version written in C using our madd function is on par with the SSE2 ATLAS version at roughly 2-3%.
Great to hear! --Michael Fawcett
