Intel MPI Incorrect Gather result error

TangY — Sun, 21 May 2023 03:18:12 GMT

Hi,

I am using Altair Feko 2022.3 and try to run a parallel computation across 2 of my Windows PC.

I had comfirmed that 2 hosts can reach to each other, but when executing the runfeko using

Intel(R) MPI Library, Version 2021.2 Build 20210318

I got the following error message:

Abort(343488527) on node 0 (rank 0 in comm 0): Fatal error in PMPI_Comm_dup: Other MPI error, error stack: PMPI_Comm_dup(168)..................: MPI_Comm_dup(MPI_COMM_WORLD, new_comm=00007FF670778EE0) failed PMPI_Comm_dup(153)..................: MPIR_Comm_dup_impl(51)..............: MPII_Comm_copy_with_info(686).......: MPIR_Get_contextid_sparse_group(490): MPIR_Allreduce_intra_auto_safe(241).: MPIR_Bcast_intra_auto(233)..........: MPIR_Bcast_intra_binomial(192)......: Failure during collective

After enable the debug message, I found it seems had some gathering issuse with the error message:

Incorrect Gather result in I_MPI_Pinning_printing

at the bottom of output.

With littel info to work with, I have no idea for now to resolve this problem. Can anyone help me, Thanks a lot.

Ps: Full debug output is in the attached text file.
