Hi all,
I just wanted to point out, for future reference, that I encountered the same problem as Andrew.
This was on the Merlin cluster at PSI Local HPC Cluster: PSI Merlin6 | AWI | Paul Scherrer Institut (PSI), and it was exactly in the same way that Andrew described, except that it didn’t hang every time. It randomly hung or finished, but most of the times it hung.
In the end openmc.deplete.pool.USE_MULTIPROCESSING=False solved my problem. Now it finishes every time.
Thanks for the discussion, this thread was very helpful.
Best,
Arnau
