Just to find out more about the consequences for exiting MPI processes without calling MPI_Finalize, will it cause memory leak or other fatal problem?
If you're exiting the process, you won't cause any kind of problems -- the OS will clean up everything.
However, we might also have the orted clean up some things when MPI processes unexpectedly die (e.g., filesystem temporary files in / tmp). So you might want to leave those around to clean themselves up and die naturally.
