It depends on the interconnect you are using. Some transports have async
progress support but others do not.

Hi,
Is there anything that can be done to boost asynchronous progress for MPI RMA
operations in OpenMPI 3.1? I’m trying to use the MPI RMA runtime in Global
Arrays and it looks like the performance is pretty bad for some of our tests.
I’ve seen similar results in other MPI implementations (e.g. Intel MPI) and it
could be fixed by setting some environment variables to boost asynchronous
progress. Is there something similar for Open MPI or can you use something like
Casper?
