You are starting 12 copies of the script. MPI documentation can be found here:

Quoting Tibor Pausz <[email protected]>:

Dear all,

i want to start a programm via a wrapper script. If I try this, MPI does
not work correct. Is their any solution to this problem?

example:
srun -n 12 -l ../wrapper_skript.sh

wrapper_skript.sh:
#setup
./my_mpi_app
#cleanup

Best regards,
Tibor
