Hi, I am trying to run the following setup in fortran without much success:
I have an MPI program, that uses mpi_comm_spawn which spawns some interface program that communicates with the one that spawned it. This spawned program then prepares some data and uses call system() statement in fortran. Now if the program that is called from system is not mpi program itself everything is running OK. But I want to run the program with something like mpirun -n X ... and then this is a no go. Different versions of open mpi give different messages before they either die or hang. I googled all the messages but all I get is just links to some openmpi sources, so I would appreciate if someone can help me explain how to run above setup. Given so many MCA options I hope there is one which can run the above setup ?? The message for 1.6 is the following: ... routed:binomial: connection to lifeline lost (+ PIDs and port numbers) The message for 1.8.1 is: ... FORKING HNP: orted --hnp --set-sid --report-uri 18 --singleton-died-pipe 19 -mca state_novm_select 1 -mca ess_base_jobid 3378249728 If this is not trivial to solve problem I can provide a simple test programs (we need 3) that show all of this.
