Hi Bernd, Thanks for your valuable input! Your suggested approach indeed seems like the correct one and is actually what I've always wanted to do. In the past, I've also asked our cluster support if there was this possibility, but they always suggested the following approach: export OMP_NUM

Helo, I'm trying to run a code implemented with OpenMPI and OpenMP (for threading) on a large cluster that uses LSF for the job scheduling and dispatch. The problem with LSF is that it is not very straightforward to allocate and bind the right amount of threads to an MPI rank inside a single
