The violated condition was:
ierr == MPI_SUCCESS
Additional information:
deal.II encountered an error while calling an MPI function.
The description of the error provided by MPI is "MPI_ERR_FILE: invalid
file".
The numerical value of the original error code is 30.
It's hard to tell what the reason may be, but let me take a guess: Are you
sure that your file system supports MPI I/O? For example, NFS-mounted file
systems do not support this, and it would lead to errors like this one.
