osu_igather Other MPI error starting at 8 nodes 96 ppn

[longfei-austin]

Errors of the following signature have been encountered when running osu_igatherv and osu_igather:

Fatal error in internal_Wait: Other MPI error

Fatal error in internal_Barrier: Other MPI error

x4003c4s1b0n0.hsn.cm.aurora.alcf.anl.gov: rank 45283 died from signal 6
x4101c5s6b0n0.hsn.cm.aurora.alcf.anl.gov: rank 256 died from signal 11
x4101c5s6b0n0.hsn.cm.aurora.alcf.anl.gov: rank 257 died from signal 15

They are more commonly encountered with next-eval, start to happen at 8 nodes.

@longfei-austin 8 nodes at what PPN?

[hzhou]

I am using 8 nodes and the aurora_test branch, running osu_igather - it works for me all the way up to 96 ppn.
