Running Hpx Program Using srun/mpiexec Error #6538

phil-skillwon · 2024-08-27T15:52:34Z

Earlier, I discussed with @JiakunYan about the issue of an HPX-based application crashing when using parcelport LCI, and we debugged it. Currently, the crash issue has been resolved.
Please refer to this link:
#6526

Available PMI with Slurm:

srun --mpi=list
MPI plugin types are...
        none
        cray_shasta
        pmi2
        pmix
specific pmix plugin versions available: pmix_v3

Here is my test code:

When I start my HPX program with different command parameters, I encounter various issues such as errors, crashes, and the program not entering the hpx_main function, depending on the command used.

Could these issues be related to the HPX runtime?
Could someone please help me?

@phil-skillwon My previous understanding is that you also get the same behavior with only one task. However, all examples you posted here are with 2 tasks. Could you confirm whether your program runs successfully with one task?

@JiakunYan
The test results for a single node and two nodes are almost the same.

JiakunYan · 2024-09-06T17:06:49Z

@hkaiser could you take a look? It appears not to be a communication bug as it can also be reproduced on a single node.

The debug version crashes, but the release version runs normally.
