Yade

avx instructions

Asked by frankie

Hello,

When running yade, I have the following message of error:

Your OS does not support AVX instructions. OpenBLAS is using Nehalem kernels as a fallback,
which may give poorer performance.

can this have an influence on the way Yade is working ? what can I do..

Frankie

Hello, it can hurt if you use FlowEngine and friends (fluid solvers).
Else you are not using openBlas.
