    Interesting to see PHP do so well on the Xeons. How does Clear's optimized PHP perform on the newest Epyc and newest Xeons?

      They'll just need to cut down the prices by 80%. Shouldn't be too hard.

        Great benchmarks! Any chance you could take a look how they do with running python+numpy in MKL vs. OpenBLAS against the Intel CPUs? We would love to get the next servers for our scientific computing needs to be AMD, but so far the complexity of MKL issues always got us to choose the safer option.

          If you can provide a reference script on how to setup and run any desired tests in an automated and reproducible manner, I'm always happy adding new test profiles to PTS.

            I have a load that is running better as many single threads. Am I better of with 2 cpu with higher base clock or 1 with an higher boost clock ? I think this is missing in the test suite.

              New test contributions / scripts always welcome.

                Do you understand why is that? My crystall ball says one of the things you want to look into is cache utilization. And you might want to pick the cpu configuration that gives you the largest caches.

                  That's why I am interested in the 7262 or the maximum of L3 for 8 cores or the 7302. I think I can fit my data in the closest L3 for reuse with 2 threads per tasks.
                  I do need ECC memory for the 3 months of crunching needed, ECC 3200 UDIMM is harder to find than the ECC RDIMM 3200... So my ram might make the EPYC cheaper than a TR...
