Hi All, I am using MPICH with sock connection. I also setup processes using dynamic connection method (MPI_Comm_connect/MPI_Comm_accept). It's a master-slave architecture where master accepts the connections from slaves. Now if one of the process dies (or get killed), I can still recover from this (without using checkpoint/restore method). For the particular process in master, I do not call MPI_disconnect (it hangs and does not complete). As a result, my MPI_Finalize in master hangs and does not complete. Do you have a workaround to forcefully complete MPI_Finalize or MPI_disconnect? I tried MPI_Comm_free on the failed connection. However, it does not solve the hang in finalize.
