Thank you - both - very much again. The "mpir_run -npx gmx -mdrun....." command was lifted from a Feb 2018 response from Szilard , to a multi gpu, user which he used as an example.
I'll crank on your pointers right now.

You installed "gmx_mpi" version 2018.4 but then your command uses "mdrun_mpi" instead. Apparently you have version 5.1.2 (perhaps from a package manager, based on the fact that it's installed in /usr/bin instead of /usr/local/gromacs/bin) that is being found in your PATH. If you've got multiple versions installed, either source GMXRC properly or use full PATH information in your commands. Above all, use the right binary name to start :) -Justin -- ========================================== Justin A.
