Ralph Castain 27a73ad9ee Fix a race condition between the orteds and HNP that can cause the orteds to output the "lost lifeline" message. ... This has been a long-time problem. I tried to reduce the problem by having the orteds tell the HNP they were finalizing, and having the HNP wait until all orteds had reported or we timed out. What was observed was that all the orteds were correctly reporting that they are leaving, but the HNP is able to exit before the orteds, thus closing the orteds lifeline socket and generating the error output. This is caused by the fact that the orteds have to whack all remaining session directories, which includes that blasted monster shared memory file! Cleaning up the SM file can take quite a while. The HNP doesn't have that problem as there is no SM file there! So it gets out first. What we had done in the past to resolve that problem was put a little test in the OOB that checks to see if we are finalizing. If we are, then we ignore the lifeline connection being lost. That check was still in the code - however, we had lost the line in orte_finalize that set the flag!! This commit was SVN r17893.		2008-03-20 13:30:51 +00:00

help-orted.txt	Bring in an updated launch system for the orteds. This commit restores the ability to execute singletons and singleton comm_spawn, both in single node and multi-node environments.	2007-07-12 19:53:18 +00:00
Makefile.am	Resolve a problem where the orte daemon comm functions were being accessed by mpirun while still retaining occasional reference to the orted_globals. Remove all dependence on orted_globals from the comm functions. Move those functions back into their own file to make it easier to maintain the separation. Ensure that mpirun ignores any "exit" commands being sent to daemons as it will exit on its own.	2007-07-23 18:36:33 +00:00
orted_comm.c	Bring some sanity to the exit code returned by mpirun. Ensure that we provide a non-zero code if something goes wrong, including someone exiting after calling mpi_init without calling mpi_finalize.	2008-03-19 19:00:51 +00:00
orted_main.c	Fix a race condition between the orteds and HNP that can cause the orteds to output the "lost lifeline" message.	2008-03-20 13:30:51 +00:00
orted.h	Cleanup recursions in ORTE caused by processing recv'd messages that can cause the system to take action resulting in receipt of another message.	2008-02-28 19:58:32 +00:00
