Thank you for your quick answer. I am trying to understand the blocking<br>
behavior of MPI_Wait in the case of non-blocking collectives. Is it safe<br>
to assume that, for a non-blocking collective, MPI_Wait is guaranteed to<br>
return once all other processes call the corresponding completion<br>
operation (e.g. MPI_Wait or MPI_Test)?<br>

I'm not sure I understand your question. Are you asking if MPI_WAIT in a process is guaranteed to return after some finite amount of time after every other process has called MPI_WAIT? Then, yes.<div class="HOEnZb">
