[petsc-users] MPI_Iprobe Error with MUMPS Solver on Multi-Nodes

Mon May 22 10:06:47 CDT 2023

Hi,

I hope this letter finds you well. I am writing to seek guidance regarding
an error I encountered while solving a matrix using MUMPS on multiple nodes:

```bash
Abort(1681039) on node 60 (rank 60 in comm 240): Fatal error in
PMPI_Iprobe: Other MPI error, error stack:
PMPI_Iprobe(124)..............: MPI_Iprobe(src=MPI_ANY_SOURCE,
tag=MPI_ANY_TAG, comm=0xc4000026, flag=0x7ffc130f9c4c,
status=0x7ffc130f9e80) failed
MPID_Iprobe(240)..............:
MPIDI_iprobe_safe(108)........:
MPIDI_iprobe_unsafe(35).......:
MPIDI_OFI_do_iprobe(69).......:
MPIDI_OFI_handle_cq_error(949): OFI poll failed
(ofi_events.c:951:MPIDI_OFI_handle_cq_error:Input/output error)
Assertion failed in file src/mpid/ch4/netmod/ofi/ofi_events.c at line 125: 0
```

The matrix in question has a degree of freedom (dof) of 3.86e+06.
Interestingly, when solving smaller-scale problems, everything functions
perfectly without any issues. However, when attempting to solve the larger
matrix on multiple nodes, I encounter the aforementioned error.

The complete error message I received is as follows:
```bash
