Hey there, I know that variable export in general can be done with the -x option of mpirun, but I guess that won't help me. More precisely I have a heterogeneous cluster (number of cores per cpu) and one process for each node. The application I need to launch uses hybrid MPI+OpenMP parallelization an I have to set the OMP_NUM_THREADS variable such that it fits the number of cores on each node.
I have no access to the application to get the number of cores from within the process. I just can launch it. Is there any chance to do this? Best regards, Kurt
