Which polling rate are you trying to adjust? And why (I'm just
This particular polling rate is slightly complicated. Think of it as
how often we progress file descriptor-based communications when *not*
using TCP as an MPI transport (e.g., when using OpenFabrics, we poll
file descriptors very infrequently -- but we still poll OpenFabrics
completion queues hard for progress; there's no way to "dial that
down", so to speak).
