<P>The mpirun or mpiexec command sets the total number of MPI tasks used
|
||||
by LAMMPS (one or multiple per compute node) and the number of MPI
|
||||
tasks used per node. E.g. the mpirun command in MPICH does this via
|
||||
its -np and -ppn switches. Ditto OpenMPI via -np and -npernode.

per physical GPU.
