      Hi, does anyone know how to configure an EPYC 7764 processor, how to configure Ls-Run, or what commands to add to the simulation I want to run to get maximum performance? I have Windows Server 2022.

      Hi, I don’t think there are any setting needed. LS-DYNA exectables are common builds that should work on both Intel and AMD hardware. If you notice any performance issues, please let us know. For LS-RUN, depending on the solver (SMP/MPP), please make sure the “expression” field reflects the correct ls-dyna solver command. If you’re running MPP, please make sure appropriate MPI is installed and mpiexec.exe is called in the command, as shown in the picture below.
