MPI competition between Parallel Studio and ONEAPI
After installing parallel_studio_xe_2020_update4_professional_edition_setup.exe and w_mpi_oneapi_p_2021.1.1.88_offline.exe, mpirt's hydra-MPI server was installed, and I need to do a separate install for oneAPI's version.
1) my guess is that only one of the two should be installed.
2) should both mpirt and oneAPI\mpi be in the same path? If so, maybe oneAPI\bin needs to appear before the mpirt path. I believe a PATH search starts with the first path on its list and proceeds to the end of the list.
