Title: Fatal error in PMPI_Init: Other MPI error, OFI endpoint open failed

1,422 Views

I am encountering a fatal error in my OpenMolcas software when running multiple processors using Intel MPI.

The error message reads: 'compute.server:rank0: PSM3 can't open nic unit: 0 (err=23) Abort(1615247) on node 0 (rank 0 in comm 0): Fatal error in PMPI_Init: Other MPI error, error stack: MPIR_Init_thread(176)........: MPID_Init(1525)..............: MPIDI_OFI_mpi_init_hook(1556): create_vni_context(2133).....: OFI endpoint open failed (ofi_init.c:2133:create_vni_context:Invalid argument) parnell failed to create a WorkDir at /home/scratch/OpenMolcas/000.6438'.

I am unsure if this error is caused by a problem with Intel MPI or a compilation issue. Can anyone help me identify the root cause of this issue and suggest a solution?

Thanks in advance for your help!"
