Hi Jeff,
thanks for taking the time to answer this. I actually reached that
conclusion after trying a simple MPI::Barrier() with both OpenMPI and
Lam-MPI , where both had the same active wait kind of behaviour.
What I'm trying to achive is to have some kind of calculation
server,
This is actually expected behavior. We make the assumption that MPI
processes are meant to exhibit as low latency as possible, and
therefore use active polling for most message passing.
Additionally, it may be possible that connections could come across
multiple devices, so we need to poll
