When reading a fits/HDF5 file from disk with a collective MPI call that has just been written to disk with rank = 0, some file not found error may be raised, see e.g. https://github.com/adematti/mockfactory/blob/7df2a96bee83db561a64188a2c5491777852c2ce/mockfactory/catalog.py#L137
(It does not seem like an issue due to processes trying to read the file at the exact same time)
