General environment variables
MPIRUN_OPTIONS MPIRUN_OPTIONS is a mechanism for specifying
additional command line arguments to mpirun. If this environment
variable is set, then any mpirun command will behave as if the
arguments in MPIRUN_OPTIONS had been specified on the mpirun
command line. For example:
% export MPIRUN_OPTIONS="-v -prot"
% $MPI_ROOT/bin/mpirun -np 2 /path/to/program.x
would be equivalent to running
% $MPI_ROOT/bin/mpirun -v -prot -np 2 /path/to/program.x
When settings are supplied on the command line, in the
MPIRUN_OPTIONS variable, and in an hpmpi.conf file, the resulting
command line is as if the hpmpi.conf settings had appeared first,
followed by the MPIRUN_OPTIONS, followed by the actual command line.
And since the settings are parsed left to right, this means the later
settings have higher precedence than the earlier ones.
