Hello Gilles,
Ok, I believe I have a simple toy app running as I think it should:
'n' parent processes running under mpi_comm_world, each one
spawning its own 'm' child processes (each child group work
together nicely, returning the expected result for an mpi_allreduce call).
Now, as I mentioned
Alex,
You need MPI_Comm_disconnect at least.
I am not sure if this is 100% correct nor working.
If you are using third party apps, why dont you do something like
system("env -i qsub ...")
with the right options to make qsub blocking or you manually wait for the end
of the job ?
That looks like
Gilles,
MPI_comm_disconnect seem to work but not quite.
The call to it returns almost immediatly while
the spawn processes keep piling up in the background
until they are all done...
I think system('env -i qsub...') to launch the third party apps
would take the execution of every call back to
