Same as https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/UE4V44DEVGGS6KT7UXEMZ7AAHHGV6U3M/ , I am just wondering what is the right thing here. The answer is to use a serial version with 32-bit integers unless another version is explicitly supported by your package or required by your dependency graph. This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle. Changing version to '31'. This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle. Changing version to 31. Unfortunately this must be deferred. Fedora 32 is already released and we must not introduce feature changes like this on Fedora 32 and 31. Well, when I opened this two years ago, Fedora 31 was rawhide. Nobody's asking you to make changes to F31 or F32 at this point. Keeping it at rawhide is the right answer here. There's a new push for FlexiBLAS instead, though, so I hope you'll consider switching to that one. Yes, F-33 has a new feature change which requests to use FlexiBLAS, so this is anyway obsolete. F-31, 32 won't be changed, F-33 won't use openblas. So anyway closing. |
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): mpqc-2.3.1-42.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: https://github.com/tmolteno/necpp/issues/18 http://blog.nguyenvq.com/blog/2014/11/10/optimized-r-and-python-standard-blas-vs-atlas-vs-openblas-vs-mkl/ https://freddie.witherden.org/pages/blas-gemm-bench/ http://nghiaho.com/?p=1726 Many Fedora packages have switched to openblas already (e.g. scalapack and all dependent ones and numpy).
