Ralph Castain a3060cdd15 Fix the bind_downward code - it was incorrectly looking across the entire node instead of only looking below the locale to which the proc had been assigned. In other words, if the proc was mapped to a core, then the only hwthreads that should be considered for binding are those directly below that core. The binding algo was incorrectly looking at ALL hwthreads in that scenario, causing the proc to be bound to an HT outside of the mapped location. ...

This now results in the procs being bound within their assigned location. It also causes us to use only the 0th HT on a core unless --use-hwthread-cpus has been specified (in which case, we use all the HTs in a core). Bind to core binds you to all HTs regardless - the --use-hwthread-cpus only impacts the oversubscribed determination and when binding to HT.

db

Add some protection to allow NULL bytes in byte objects and NULL strings to be handled cleanly in nidmaps and modex entries. Ensure there is a valid nidmap available for the HNP to pass down to any local procs when it is operating alone.

errmgr

Complete the cleanup of the preload files system. Remove the dest_dir option as moving things to arbitrary locations - especially absolute paths - can prove disastrous. Remove the preload_libs option as these can be treated as just files. Cleanup some of the pack/unpack code as the dss handles NULL strings just fine. Deal a little better with absolute paths, noting that tar now strips the leading '/' for us (showing my age as it didn't used to do so).

Multiple apps might want the same files, so instead of using the app_idx to determine who gets what, use the actual file names as they are sent anyway

odls

Cleanup comm_spawn for the multi-node case where at least one new process isn't spawned on every node. Avoid the complexities of trying to execute a daemon collective across the dynamic spawn as it becomes too hard to ensure that all daemons participate or are accounted for - instead, use a less scalable but workable solution of sending the data directly between the participating procs. Ensure that singletons get their collectives properly defined at startup so the spawned "HNP" is ready for them.

routed

Introduce staged execution. If you don't have adequate resources to run everything without oversubscribing, don't want to oversubscribe, and aren't using MPI, then staged execution lets you (a) run as many procs as there are available resources, and (b) start additional procs as others complete and free up resources. Adds a new mapper as well as a new state machine.
