Dear all,
We would like to execute a MPMD program by srun which is basically possible using the "--multi-prog" option for srun. Let's assume, we only have two different executables which should be executed by a single srun command (so, the same "MPI_COMM_WORLD" is used).
Is it possible to pass different binding parameters (e.g., different --cpu_bind=mask_cpu:<mask1>,<mask2>,...) and/or environment variables to the different executables specified in the multiple program configuration?
For instance,
- one of the executables is using MPI processes and OpenMP threads whereas the second executable only uses MPI processes. Here, we would like give a different cpu_bin=mask_cpu for the different executables.
- both executables are hyprib MPI/OpenMP programs where OMP_NUM_THREADS should be set to 2 for the first executable and the second executable should fork 4 OpenMP threads. Here, we would like to pass different environment variables (OMP_NUM_THREADS) to the executables.
Please note that with, e.g., IntelMPI this is possible because -env can be specified for every executable.
Best regards,
Oliver
