Description Dominik 'Rathann' Mierzejewski 2017-07-18 13:04:06 UTC 
Description of problem:
Please BuildRequire: openblas instead of atlas where available (currently: x86_64 %{ix86} armv7hl %{power64} aarch64 s390x, see %{openblas_arches} macro defined in openblas-srpm-macros package).

Version-Release number of selected component (if applicable):
1.13.1-1.fc27

Additional information:
A lot of benchmarks around the net suggest openblas is faster than ATLAS in most workloads:

Many Fedora packages have switched to openblas already (e.g. scalapack and all dependent ones).
