Short description: major changes include - 1. singletons now fork/exec a local daemon to manage their operations. 2. the orte daemon code now resides in libopen-rte 3. daemons no longer use the orte triggering system during startup. Instead, they directly call back to their parent pls component to report ready to operate. A base function to count the callbacks has been provided. I have modified all the pls components except xcpu and poe (don't understand either well enough to do it). Full functionality has been verified for rsh, SLURM, and TM systems. Compile has been verified for xgrid and gridengine. This commit was SVN r15390.
