If i may, you can use the command line option "-mat_mumps_icntl_4 2"
MUMPS then gives infomations about the factorization step, such as the

This is solved with four nodes, each equipped with 500G of memory.

Thank you for your suggestion. I solved the problem with SuperLU_DIST, and
it works well.

Hi,
I hope this letter finds you well. I am writing to seek guidance regarding

```bash
Abort(1681039) on node 60 (rank 60 in comm 240): Fatal error in
