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
