Rerefencing the following issue and linked PR and discussion, I made some changes to the package(here) to make GIMP work and remove glibc deadlocks. Do you think it would be nice to include it, while it's still resolved?

Update is out: https://github.com/xianyi/OpenBLAS/archive/v0.3.2.tar.gz

OpenBLAS 0.3.1 is broken when running multi-threaded. Rediscovered this myself, then found https://github.com/xianyi/OpenBLAS/issues/1666 and https://github.com/xianyi/OpenBLAS/issues/1673 Workaround is OPENBLAS_NUM_THREADS=1

Until fix is released, please revert to 0.3.0 (or 0.2.20?). Who here wants their BLAS to be giving incorrect results? Scary that it's been broken for a month now. How many people's work for the past month has been ruined? Author is in no hurry to release a fix, either.

This package should not track upstream so aggressively!

Typo: USE_OPENMP, not USE_OPENMPI

Rufflewind commented on 2018-07-16 01:08

There is a compatibility issue with GIMP that causes GIMP to hang during startup.

Workaround: rebuild openblas-lapack with USE_OPENMPI=1 (see PKGBUILD file) instead of USE_OPENMP=0.

The dependency gcc-libs changes the version number of shared library libgfortran.so.5 from 4 to 5. I suggest to increase the pkgrel to enforce re-building of this package.

@asitdepends: why do you need static libs? If you want them, you juste need to staticlibs to the options

asitdepends commented on 2018-03-11 14:04

Would you update the package to make the static libraries also?

I know, OMP_NUM_THREADS has the same effect. But I am getting slightly better performance when I compile without multithreading. Probably because it reduces overhead.

@MaartenBaert If you're using OpenBlas in a multi-threaded application the simplest thing is to disable threading by setting environment variable OPENBLAS_NUM_THREADS to 1. No need to recompile.
