un do it without too much fuss, though it
would require a message as opposed to a signal so you can indicate how many
procs to "idle/kill".

I have an mpi-based program that has a master process that acts as a 'traffic
cop' in that it hands out work to child processes.
I want to be able to dynamically throttle how many child processes are in use
at any given time.
For instance, if I start it with "mpirun -n 512" I could send a

Generally, if you built openmpi with PBS support, it will automatically using
the appropriate nodes with ‘mpirun ’
If not, you can use the environment variables provided to your session:
mpirun --hostfile $PBS_NODEFILE -np $(cat $PBS_NODEFILE|wc -l)

I have been unable to compile OpenMPI 1.8 using PGI compilers (13.6, 13.10 or
14.3)

All,
I have some sample code that has a syntax message and then an MPI_Abort call if
the program is run without the required parameters.
--snip---
if (!rank) {
i = 1;
while ((i < argc) && strcmp("-input", *argv)) {
i++;
argv++;
