The problem was tracked to use of the grpcomm.onesided_barrier to control daemon/mpirun termination. This relied on messaging -and- required that the program counter jump from the errmgr back to grpcomm. On rare occasions, this jump did not occur, causing mpirun to hang. This patch looks more invasive than it is - most of the affected files simply had one or two lines removed. The essence of the change is: * pulled the job_complete and quit routines out of orterun and orted_main and put them in a common place * modified the errmgr to directly call the new routines when termination is detected * removed the grpcomm.onesided_barrier and its associated RML tag * add a new "num_routes" API to the routed framework that reports back the number of dependent routes. When route_lost is called, the daemon's list of "children" is checked and adjusted if that route went to a "leaf" in the routing tree * use connection termination between daemons to track rollup of the daemon tree. Daemons and HNP now terminate once num_routes returns zero Also picked up in this commit is the addition of a new bool flag to the app_context struct, and increasing the job_control field from 8 to 16 bits. Both trivial. This commit was SVN r23429.

it should; but when it *is* doing something, we do not want it

processor in the middle of its work.

For example: when a message arrives at orterun, we want the

OS to wake us up in a timely fashion (which most OS's

seem good about doing) and then we want orterun to process
|

the message as fast as possible. If orterun yields and lets

aggressive MPI applications get the processor back, it may be a

long time before the OS schedules orterun to run again
|

(particularly if there is no IO event to wake it up). Hence,

|
routed OOB messages (for example) may be significantly delayed
|
|
before being delivered to MPI processes, which can be

problematic in some scenarios (e.g., COMM_SPAWN, BTL's that
