Description Dominik 'Rathann' Mierzejewski 2018-08-20 00:21:40 UTC
Description of problem:
Please BuildRequire: openblas instead of atlas where available (x86_64 %{ix86} armv7hl %{power64} aarch64 s390x, see %{openblas_arches} macro defined in openblas-srpm-macros package). Currently, it's available on all primary Fedora arches, so you can technically skip using the macro.

Version-Release number of selected component (if applicable):
libcint-3.0.4-3.fc28

Additional information:
OpenBLAS selects best code path for the target architecture at runtime unlike ATLAS.

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 and numpy).

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Automation has figured out the package is retired in Fedora 31.

If you like it to be unretired, please open a ticket at https://pagure.io/releng/new_issue?template=package_unretirement
