poor performance on i9
Posted: Thu Oct 27, 2022 6:47 am
Hi,
we've just installed a new desktop with 12th Gen Intel(R) Core(TM) i9-12900F, 32G RAM, 1T SSD, Ubuntu 22.04 with the latest updates. VASP 6.3.2 compilation following the procedure given in "Building VASP 6.3.X on Ubuntu 22.04" went without any issues.
"make test" however, didn't finish after 20 hours. A simple lattice parameter relaxation calculation that takes about a minute on a similar machine equipped with AMD Ryzen 9 5950X 16-Core Processor, takes here more than one hour.
Could you please suggest where I should start troubleshooting, since I believe it must be a software issue.
Regards.
