...thlon 2600 MP desktop (about to be replaced). Goto no longer supports that chip, and ACML is not threaded (for gcc). ACML was a little faster than ATLAS, which was faster than MKL. However, MKL exploited the two processors to halve the elapsed time. MKL on that chip is poor on complex linear algehra. On 64-bit Linux I used a dual Athlon 248. Here the Goto BLAS was the fastest, but only just faster than ACML when using one CPU. ATLAS was slightly slower, and MKL perhaps 20% slower but good at exploiting 2 CPUs. This time it was not relatively slower at complex algebra. On Windows ACML i...
