There's a compile-time option for openblas that is apparently

functional in 0.3.7 than it used to be. Quoting Makefile.rule:
"If any gemm argument m, n or k is less or equal to
[GEMM_MULTITHREAD_THRESHOLD], gemm will be execute with single thread.
It might be worth trying the Julia value of 50. But this is
applicable
only to our builds for Windows, or for people building the openblas
library themselves (e.g. on Linux). I haven't experimented yet but I
plan to.
I had read about that, yes, but doesn't GEMM just apply to
multiplication? Would this affect solvers as well?
