<div class="">I am by far not an expert on MPI dynamic process at this point. I will point you to the MPI standards <a href="https://www.mpi-forum.org/docs/" class="">https://www.mpi-forum.org/docs/</a>, in particular, chapter 10. MPICH implements most of the
standards. Try follow the standards to see what you can do. If you hit specific problem, post back here and some one will help you. </div>

<div dir="auto" class="">I have a question about if mpich can do dynamically allocate/schedule/kill process on the runtime? If that’s doable, how can we do that? </div>

<div dir="auto" class="">Distribute mpich application on 8 processes each on a single machine. During the application runtime, can we dynamically (allocate & start)/(remove & kill) one process and (add to)/(delete from) the current communication group ? </div>
