Ralph Castain 86d55d7ebf Fix tight loops over comm_spawn by checking to see if the system has enough child procs and file descriptors available before attempting to launch. If not, introduce a 1sec delay and then test again. This provides a chance for the orted to complete processing of proc terminations from other children, hopefully creating room for the new proc(s). ...

Update the loop_spawn test to remove a sleep so that it runs at max speed, letting the new code catch when we overrun ourselves and wait for room to be cleared for the next comm_spawn.

This commit was SVN r21390.

abort.c

Here is the major MAD-cure commit. I have written plenty about it, so I refer you here to those messages for a description of everything that was done.

2006-09-14 21:29:51 +00:00

accept.c

Repair the MPI-2 dynamic operations. This includes:

2008-07-03 17:53:37 +00:00

bad_exit.c

These changes were mostly captured in a prior RFC (except for #2 below) and are aimed specifically at improving startup performance and setting up the remaining modifications described in that RFC.

2007-10-05 19:48:23 +00:00

cell_spawn.c

Update the slave launch and cleanup procedures. Track what files have been moved to the slave node to avoid attempting to copy them multiple times on top of each other. Cleanup any pre-positioned files, kill any lingering apps, and cleanup the session directory area upon termination of the daemon.

2009-04-29 00:11:19 +00:00

concurrent_spawn.c

Commit a few missing header files, etc.

2008-09-24 15:41:42 +00:00

connect.c

Cleanup and fix bugs in the MPI dynamics section. Modify the dpm API so it properly takes ports instead of process names (as correctly identified by Aurelien). Fix race conditions in the use of ompi-server. Fix incompatibilities between the mpi bindings and the dpm implemenation that could cause segfaults due to uninitialized memory.

crisscross.c

Add new test that stresses MPI send/recv

2008-09-09 15:47:31 +00:00

delayed_abort.c

Add a delayed_abort test code. We seem to handle this case just fine now, but Sun reports still seeing troubles on Solaris.

mpi_spin.c

Add another test program - an MPI app that just spins. This supports testing of system response to signal-terminated processes.

2006-11-13 21:51:34 +00:00

multi_abort.c

One more correction to mpirun exit codes - cleanup the application proc's exit codes in the orted so that non-zero exit codes generated by mpirun itself don't get "munged".

2008-03-20 13:54:11 +00:00

pubsub.c

Fix ompi-server so it works with unity routed module - still not working with tree routing.

2008-10-25 14:38:06 +00:00

reduce-hang.c

Cleanup the nidmap lookup functions and add some comments explaining how we handle the nid, job, and pmap arrays. This fixes a problem we have less-than-full participation in a comm_spawn, causing holes to exist in the pmap array.

Roll in the revamped IOF subsystem. Per the devel mailing list email, this is a complete rewrite of the iof framework designed to simplify the code for maintainability, and to support features we had planned to do, but were too difficult to implement in the old code. Specifically, the new code:
