For pm-cpu, remove libfabric work-around of setting `FI_CXI_RX_MATCH_MODE-software`

Open ndkeen opened this issue 1 year ago • 2 comments

We had been using FI_CXI_RX_MATCH_MODE-software on pm-cpu to avoid some issues when Perlmutter was young. There was no measurable performance difference, so did not change this setting. Now let's try removing this and letting it use the default which is FI_CXI_RX_MATCH_MODE-hybrid.

what kind of testing have you done?

In general, I've done quite a bit of testing with this over the years -- with various cases looking for performance changes (there were not any). I'm sure I've run integration before and I can run again, but don't expect any surprises.
