Source: fenics-dolfinx Followup-For: Bug #1127800 X-Debbugs-Cc: [email protected]
I'm confident now that Bugs #1127672 and #1127800 are triggered by the same underlying issue. I could clear out problems importing dolfinx on my local machine by clearing the fenics cache rm -r ~/.cache/fenics/ After that I can reproduce issues with the same 5 tests found failing on the 32-bit arches (with mpich) on my local machine (amd64 with openmpi). The difference is that serial tests (including mpirun -n 1) pass with openmpi where they fail with mpich (#1127672) The other difference is that nanobind with mpich triggers the "incompatible function arguments" error reported in the 5 tests in #1127672, while with multiprocess openmpi (mpirun -n 2) the first test (test_read_write_mixed_topology in test_vtkhdf.py) times out (#1127800), so debci doesn't get to see the problem with the other 4 tests.
