Hi Jurij I have installed the latest version of OpenBLAS(0.3.6), it the seems the matrix calculations are correct now. Fyi: I am using EasyBuild 3.9.0, so it did not require the https://github.com/easybuilders/easybuild-easyconfigs/pull/8227 patch

I've recently checked OpenBLAS changelog and saw some adding-removing-adding-removing specific avx512 kernels there. I'd suggest trying the latest OpenBLAS release and see if that fixes issues you're seeing. Alternatively figure out a way to force OpenBLAS to use only avx2 and see if that helps. -- Jurij Pečar HPC Engineer, IT Operations, IT Services EMBL Heidelberg, Meyerhofstraße 1, 69117, Heidelberg, Germany Room 13-401
