https://bugzilla.redhat.com/show_bug.cgi?id=1112864 --- Comment #19 from Dave Love <d.love@xxxxxxxxxxxxxxx> --- (In reply to Dominik 'Rathann' Mierzejewski from comment #15) > It is build against atlas now. openblas doesn't support ARM yet. Do you > think it's worth it to build against openblas on x86/x86_64 and atlas on ARM? I don't know what difference it makes in this case, but I'd expect openblas to be maybe twice as fast on sandybridge for DGEMM-based things, at least with the packaged versions. However, when I tried to compare atlas recently, I got strange, non-reproducible results that I haven't tried to understand. If the tests in the ELPA source make a reasonable benchmark, I could maybe try, but I think they didn't run for long. cp2k built with openblas, fftw, and openmpi actually seemed to out-perform a version built with all-intel on a similar cluster on the one case I had a report for, but I haven't tried very serious comparisons, and I've just discovered that the Fedora fftw isn't avx enabled. I'd forgotten to file an issue suggesting it should use openblas. -- You are receiving this mail because: You are on the CC list for the bug.
