Hello Andrew,
Recently I am using OpenMC for depletion on the UMich supercomputer Greatlakes. I installed OpenMC from source for MPI parallelization, which worked perfectly for steady-state transport simulations. When I learned to perform depletion calculations using the PythonAPI, I do not know how to instruct OpenMC to run in MPI parallelization. Since the transport simulation is much more time-consuming than depletion part, probably we can somehow let OpenMC execute in MPI mode while doing depletion serially or in OpenMP parallelization as a remedy for now. Can we do that?
Best,
Puran
