When i used --map-by slot:pe=8, i got the same message
Your job failed to map. Either no mapper was available, or none

that list.
Of course, I'm also assuming that you installed the two versions into different
locations - yes?
Also, add "--mca rmaps_base_v
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.
Unfortunately, that has never been supported. The problem is that the embedded
mpirun picks up all those MCA params that were provided to the original
application process, and gets hopelessly confused. We have tried in the past to
figure out a solution, but it has proved difficult to separate th

Yes, this works! Very good trick... The system routine would be more
flexible, b
