It depends on the interconnect you are using. Some transports have async progress support but others do not. -Nathan On Aug 06, 2018, at 11:29 AM, "Palmer, Bruce J" wrote: Hi,   Is there anything that can be done to boost asynchronous progress for MPI RMA operations in OpenMPI 3.1? I’m try

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.
