The `$${NPROCS:=6}' will be substituted with the value of the NPROCS
environment variable at the time `make check' is run (or the value 6).
RUNPARALLELSCRIPT is identical to RUNPARALLEL but is used in parallel shell
scripts and lacks the environment variable protection.
RUNPARALLELSCRIPT: mpiexec -n ${NPROCS:=6}
Note that some MPI implementations (e.g. OpenMPI 4.0) disallow oversubscribing
nodes by default so you'll have to either set NPROCS equal to the number of
processors available (or fewer) or redefine RUNPARALLEL(SCRIPT) with appropriate
processors available (or fewer) or redefine RUNPARALLEL with appropriate
flag(s) (--oversubscribe in OpenMPI).
