[Zhou, Hui]

You don’t need any special settings to use non-blocking MPI collectives in MPICH.

Subject: [mpich-discuss] Question about non-blocking MPI - 3
Hello everyone,

What is the environment setting for the use of non-blocking MPI-3 * collectives in mpich3.3?

In Intel MPI, the setting is as follows

$ export I_MPI_ASYNC_PROGRESS=1
$ export I_MPI_ASYNC_PROGRESS_PIN=<CPU list>

Is there an equivalent setting in mpich3.3?
Thank you,
Viet.
