[mpich-discuss] how to dynamically schedule process in mpich

[Shuwei Zhao]

Hi, Experts,

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?

Let’s see an example:
qsub -P my_queue -pe mpi 8 mpiexec my_exe
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 ?

Appreciate your help ahead!

Thanks,
Shuwei
