Enable full operations under SLURM on Cray systems by co-locating a daemon with mpirun when mpirun is executing on a compute node in that environment. This allows local application procs to inherit their security credential from the daemon as it will have been launched via SLURM

Try again to get an error message printed when a daemon fails to successfully report back to mpirun. In this case, there is no guaranteed way for the daemon to output the error report itself - we don't have a connection back to the HNP, and we have tied stderr off to /dev/null (for good reasons). So the HNP has to detect the failure itself and report it.
...
The HNP can't know the precise reason, of course - all it knows is that the daemon failed. So output a generic error message that provides guidance on probable causes.

Enable comm_spawn of slave processes, currently only active for the rsh, slurm, and tm environments. Establish support for local rsh environments in the plm/base so that rsh of local slaves can be done by any environment that supports it. Create new orte_rsh_agent param so users can specify rsh agent from outside of rsh plm, and sym link that to the old plm_rsh_agent and pls_rsh_agent options.
...
Modify the orte-bootproxy to pass prefix for the remote slave to support hetero/hybrid scenarios
