Getting MPI Error

[DTV7]

Hello FDS community,
I am getting the below error while trying to run one fds case in HPC. Could you kindly help me in this?

Abort(17) on node 104 (rank 104 in comm 0): Fatal error in PMPI_Testall: See the MPI_ERROR field in MPI_Status for the error code
Abort(17) on node 106 (rank 106 in comm 0): Fatal error in PMPI_Testall: See the MPI_ERROR field in MPI_Status for the error code

Thanks in advance

This indicates that something went wrong during an MPI communication. If you post your input file, I can run it and see if I get the same error. How far into the run does the error occur?

Dr. McGrattan,

I'm running into an issue right after initialization when trying to execute the simulation using multiple MPI processes. Interestingly, the file runs without any problems in single-core mode, but the error appears only during parallel execution.
Since the file contains sensitive data, I'm unable to share it publicly. Would it be alright if I sent it to your email for further review?

Thank you for your time and support.

No, because then everyone would send us files privately. That defeats the purpose of an open forum. I suggest the following:

1. Try using the latest version of FDS, even the nightly build.
2. Simplify the case to the point where there is nothing of concern to a client.
