Okay so on one compute node (20 cores, 2 sockets) works fine, even with the warning (originally my code hangs at 20 cores). However, if my sbatch script calls for more than one compute node my program freezes for anything > 20 processes. However, this also happens when I use MPICH. Now I am not sure if it's simply an issue with our university's HPC system or if MPICH also has the same problems as OpenMPI.
Hmm, plausibly something goes wrong somewhere in code generation (such that different processes go down different code paths). Can you try running with: parameters["pyop2_options"]["check_src_hashes"] = True Cheers, Lawrence -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJV3DBbAAoJECOc1kQ8PEYv4Y4IANlMFr5WBIXWIAxTKaTQyACe ymVqIZzF97AxYRpvO5WXTDGTwcPYCWEOlBGoAq9vf6xNqGHBYsoKBf0tSv0gY7bb I7wyWqJvwFRpUsSgvZN5XR7nU0+jMPpaZ5m6m8Md8PLHQnmvErUJjgmnss+Nc//p A4ioYfmK0YNzk+simOb3wAeYFM5lCtvw+8W/1Ll6XeUEyaStzQ9ZDRRLi7DR/Ikq gdz5YvzLrpQHPMVQXnT8NcGxvsIJPXmwMENMsZ9M2lCCE0qcziaIvK7HHjGGTnEP NjvTRWy5PZOpn2r5tPd7T7VYSRIZX3hkW9vTtnhny1Msg1f6EgtszWmHJCxgouY= =NMSC -----END PGP SIGNATURE-----
