FYI, Is this the right way to adjust the polling frequency in ompi?
Which polling rate are you trying to adjust? And why (I'm just curious)?
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).
