<p class="MsoNormal">Two questions:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a group of manager processes, each of which uses MPI_Comm_spawn() to create individual worker processes one at a time.
<o:p></o:p></p>
<p class="MsoNormal">Occasionally, a worker has to exit and is replaced by another worker via MPI_Comm_spawn(). If the exiting worker calls MPI_Finalize(),
<o:p></o:p></p>
<p class="MsoNormal">will it sit there waiting for all other managers and workers in MPI_COMM_WORLD to do the same, or will it wait only for the manager
<o:p></o:p></p>
<p class="MsoNormal">that created its inter-communicator to call MPI_Finalize?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In either case, maybe it is better for the worker to NOT call MPI_Finalize at all so that it doesn’t sit there taking up a core’s resources
<o:p></o:p></p>
<p class="MsoNormal">while it waits for the others. What are the implications of not calling MPI_Finalize in the workers?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
