Hi Loris,
there are some LAPACK tests that are very sensitive to floating point
rounding, in particular those involving complex numbers,
vectorization, and fused-multiply-addition (FMA).
Most of these have been addressed by GCC patches, but it depends a bit
on the compilation flags you are using for OpenBLAS, and if you use
`-march=native`, the CPU architecture you are using.
If you haven't (re)compiled GCCcore 11.3.0 since October last year,
please do so first, and see if that fixes the issue.
Otherwise you can try compiling with
toolchainopts = {'vectorize': False}
in the easyconfig.
Cheers,
Bart
