Add a new function to opal_progress that tells us our recursion depth to support that solution.
Yes, I know this sounds picky, but good ol' Jeff managed to make it happen by driving his cluster near to death...
Also ensure that we declare "failed" for the daemon job when daemons fail instead of the application job. This is important so that orte knows that it cannot use xcast to tell daemons to "exit", nor should it expect all daemons to respond. Otherwise, it is possible to hang.
After lots of testing, decide to default (again) to slurm detecting failed orteds. This proved necessary to avoid rather annoying hangs that were difficult to recover from. There are conditions where slurm will fail to launch all daemons (slurm folks are working on it), and yet again, good ol' Jeff managed to find both of them.
Thanks you Jeff! :-/

to modify the callback array (add or remove), make sure we don't call
the same callback twice if it get remove in another thread.
This commit was SVN r18608.
in a callback from the event library and post an RML receive, we'll
deadlock because the event library wouldn't be entered until the
event library was not already entered. Now just protect data structures
(which we were basically already doing) instead of code, like good
threading people ;).

the same time, remove some of the MPI-related options from OPAL:
- provide mechanism to change at runtime whether sched_yield() should
be called when the progress engine is idle
- provide mechanism for changing the rate at which the event engine
is called when there are "no" users of the event engine (ie, when
using MPI but not TCP)
- fix some function names in the progress engine to better match
their intended use (and remove MPI naming scheme)
- remove progress_mpi_enable / progress_mpi_disable because
we can now use the functions to set the sched_yield and
tick rate interfaces
- rename opal_progress_events() to opal_progress_set_event_flag()
because the first really isn't descriptive of what the function
does and I always got confused by it

did pre-libevent update. The problem is that the behavior of
OPAL_EVLOOP_ONCE was changed by the OMPI team, which them broke things
during the update, so it had to be reverted to the old meaning of
loop until one event occurs. OPAL_EVLOOP_ONELOOP will go through the
event loop once (like EVLOOP_NONBLOCK) but will pause in the event
library for a bit (like EVLOOP_ONCE).
fixes trac:234
This commit was SVN r11081.
The following Trac tickets were found above:
Ticket 234 --> https://svn.open-mpi.org/trac/ompi/ticket/234
- initial support for gm progress thread
- corrected threading issue in pml
- added polling progress for a configurable number of cycles to wait for threaded case
This commit was SVN r9188.
- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

to opal_progress() to use the timers instead of a tick count for deciding
whether to call the event loop or not. Currently supported platforms are:
- solaris (x86 / sparc)
- Linux (x86 / x86_64 / IA64)
- Mac OS X (x86 / Power PC)

ompi/).
- There's still a handful of places that have orte/ #include files;
still need to clean those up
- A lot of places still use ompi/include/constants.h -- those need to
be converted over to use OPAL_ return codes and then switch to the
opal constants.h. This commit is the first few steps towards
that...
This commit was SVN r6843.
Might want to bump this higher?
* remove assumption that progress functions registered with opal_progress
are not reentrant. There is still the assumption that the event loop
is not reentrant (because it's not), so that part is still protected by
a spinlock.

- only call sched_yield if it exists
- don't fail out if modex doens't work in ob1
- bunch of fixes for Portals BTL
- add cnos rml component
- add NULL gpr component (should only be used if replica AND proxy
fail to load)
