Description Dominik 'Rathann' Mierzejewski 2018-08-18 16:34:15 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):
ceres-solver-1.13.0-6.fc29

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).
