Change the determination of #spawn threads to be done on basis of #local procs in first job being spawned. Someone can look at an optimization that handles subsequent dynamic spawns that might be larger in size. Leave the threads running, but blocked, for the life of the daemon, and use them to harvest the local procs as they terminate. This helps short-lived jobs in particular. Add MCA params to set: * max number of spawn threads (default: 4) * set a specific number of spawn threads (default: -1, indicating no set number) * cutoff - minimum number of local procs before using spawn threads (default: 32) Signed-off-by: Ralph Castain <rhc@open-mpi.org>
