[petsc-users] Petsc on AMD EPYC

[Blaise A Bourdin]

Hi,

I am pricing out a new small cluster for my group and have been out of the HW loop for a while.
Does anybody on the list have experience running petsc on recent generation AMD EPYC?
I assume that the intel will not generate optimized code for non-intel COU. How about gcc / clang? 
My metric is not pure performance but rather performance over price.

I do mostly implicit finite element codes and 90% of my walltime is KSP / SNES solves

Regards,
Blaise
