Hi, I am using a code which is based on petsc (and also parmetis). Recently I made the following changes and now the code is running about two times faster than before:
- Upgraded Ubuntu 18.04 to 20.04 - Upgraded petsc 3.13.4 to 3.14.5 - This time I installed parmetis and metis directly via petsc by --download-parmetis --download-metis flags instead of installing them separately and using --with-parmetis-include=... and --with-parmetis-lib=... (the version of installed parmetis was 4.0.3 before) I was wondering what can possibly explain this speedup? Does anyone have any suggestions? Thanks, Mohammad
