HP XC System Software Installation Guide Version 3.1

The PBS Professional documentation for the pbs_mpihp wrapper recommends replacing the HP MPI
mpirun command with a symbolic link to pbs_mpihp to make the presence of PBS Professional completely
transparent to HP MPI users.
On systems where PBS Professional is the only active queuing system, this transparency might be desirable.
However, on systems installed and configured with SLURM and PBS Professional, you must first determine
if this configuration is appropriate for your needs. For more information, see the pbs_mpihp manpage and
the PBS Professional Administrator's Guide.
