It depends on the transport used. If there is a high-performance network (Cray
Aries, Infiniband, etc) then the progress is handled by the hardware. For other
networks (Infinipath, Omnipath, TCP, etc) there are options.
For TCP you can set:
--mca btl_tcp_progress_thread 1
No such option curr
Hi all,
I used to work with MPICH. I am trying now to compare and switch to OpenMPI. I

My questions are:
1. What would
