This bug likely will have to wait, because right now openblas seems to be broken in rawhide: # mock -r fedora-rawhide-x86_64 .... ... Cannot download Packages/o/openblas-srpm-macros-2-4.fc29.noarch.rpm: All mirrors were tried ... Furthermore, all attempts to test-build against openblas in fc28 also failed for yet undetermined reasons. > because right now openblas seems to be broken in rawhide: > > # mock -r fedora-rawhide-x86_64 .... > ... > Cannot download Packages/o/openblas-srpm-macros-2-4.fc29.noarch.rpm: All > mirrors were tried > ... Did you update to the latest mock-core-configs-29.2-1.fc28.noarch ? That's assuming you are on F28. > Furthermore, all attempts to test-build against openblas in fc28 also failed > for yet undetermined reasons. Do you have koji (scratch) build link? I could take a look then.

No. This package wasn't available until this morning. Presumably, I am once again victim of dnf not checking mirrors for currentness (== redirecting to outdated and broken mirrors) and me being in Europe (== 24-48 hrs delay until packages land) :( > > Furthermore, all attempts to test-build against openblas in fc28 also failed > > for yet undetermined reasons. > > Do you have koji (scratch) build link? Not yet, but will likely do so when I feel it's appropriate. ATM, things are still in an "too early" stage (building freefem++ is very time consuming ;) ) (In reply to Ralf Corsepius from comment #3) > (In reply to Dominik 'Rathann' Mierzejewski from comment #2) > > > because right now openblas seems to be broken in rawhide: > > > > > > # mock -r fedora-rawhide-x86_64 .... > > > ... > > > Cannot download Packages/o/openblas-srpm-macros-2-4.fc29.noarch.rpm: All > > > mirrors were tried > > > ... > > > > Did you update to the latest mock-core-configs-29.2-1.fc28.noarch ? > No. This package wasn't available until this morning. > > Presumably, I am once again victim of dnf not checking mirrors for > currentness (== redirecting to outdated and broken mirrors) and me being in > Europe (== 24-48 hrs delay until packages land) :( I got it from updates-testing on Saturday afternoon. And, as you know, I'm based in Poland. > > > Furthermore, all attempts to test-build against openblas in fc28 also failed > > > for yet undetermined reasons. > > > > Do you have koji (scratch) build link? > Not yet, but will likely do so when I feel it's appropriate. ATM, things are > still in an "too early" stage (building freefem++ is very time consuming ;) ) Sure, no rush. I know, I'm the former maintainer. ;) This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle. Changing version to 31. Closing in favour of FlexiBLAS. |
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): freefem++-3.59-2.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).
