Anyway to make Intel MPI run with event-driven instead active polling?

Jump to solution
Hi all, By default, IMPI keeps polling and take 100% of CPU when communicating. Anyway to make it event-driven to reduce the CPU load? Thanks.

Sorry guys. Just read the release note found that:

Intel MPI use CQ Polling mode as a default.
To switch to wait mode add the following to mpiexec command:
     -genv I_MPI_WAIT_MODE 1
