<div>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Hello everyone,<br>
<br>
What is the environment setting for the use of non-blocking MPI-3 * collectives in mpich3.3?<br>
<br>
In Intel MPI, the setting is as follows<br>
<br>
$ export I_MPI_ASYNC_PROGRESS=1<br>
$ export I_MPI_ASYNC_PROGRESS_PIN=<CPU list><br>
<br>
Is there an equivalent setting in mpich3.3?<br>
Thank you,<br>
Viet.<o:p></o:p></p>
