I'm using an infiniband interconnect. Am I guaranteed asynchronous progress without doing anything else? For example, to get asynchronous progress with Intel MPI, you need to set the environment variable I_MPI_ASYN_PROGRESS.

Some transports have async progress support but others do not. -Nathan On Aug 06, 2018, at 11:29 AM, "Palmer, Bruce J" <[email protected]> wrote: 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? ?
