That would be great.
<div class="">What would be even greater would be if I could run the same test on LSU machines (Xeon 8260). </div>

I am pricing out a new small cluster for my group and have been out of the HW loop for a while.<br class="">
Does anybody on the list have experience running petsc on recent generation AMD EPYC?<br class="">
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.<br class="">

I have a 2-socket 7452, which is a great price point for our sort of work. If you're purely memory bandwidth-limited, you can get fewer cores, but that doesn't save a lot of money. You'd probably want to compare pricing with the new Zen 3 chips too. I'll forward
you a log file from a multigrid solver with some analysis. Suffice it to say, it matches to significantly outperforms (depending on the operation) a 2-socket Xeon 8280.<br class="">
