Hello everyone,

I am getting those annoying messages before the header when I run OpenFOAM on a Standard HB120rs v3 (120 vcpus, 448 GiB memory) machine on Microsoft Azure. it's an AMD Epyc machine.

I noticed that I don't get these lines when I choose an Intel machine.

Can anyone help me explaining what are these lines are trying to tell me?
