mechanisms (such as epoll) if someone (ompi_mpi_init()) requests
otherwise. See big comment in opal/event/event.c for a full
explanation.

Clarify the setting of send_first in the mpi bindings (trivial, i know, but helpful)
Remove the extra xcast of child contact info to the parent job.
This commit was SVN r17952.
Reogranize the grpcomm code a little to provide support for soon-to-come new grpcomm components. The revised organization puts what will be common code elements in the base to avoid duplication, while allowing components that don't need those functions to ignore them.

initialized. For example, there is a period of time during
ompi_mpi_init when orte_initialized==true, but
ompi_mpi_initialized==false (and therefore communicators are not setup
yet, etc.).
This commit was SVN r17937.
Only one place used the user name field - session_dir, when formulating the name of the top-level directory. Accordingly, the code for getting the user's id has been moved to the session_dir code.
This commit was SVN r17926.
Greatly reduce the number of "foo" -> "opal_foo" symbol renames in the
libevent source, and instead greatly expand the event_rename.h file
that uses preprocessor macros to make all public symbols be
"opal_foo".
This commit was SVN r17923.
some cleanups and standardizations in the various */tools/*/
Makefile.am files. This commit:
* Somewhat simplify the tool Makefile.am's
* Makes the tool Makefile.am's consistent with each other (do similar
actions in similar ways)
* Update the tool Makefile.am's to remove old kruft that was required
by older versions of AM (trunk requires AM >=1.10)

still-broken trunk build on common platforms (e.g., 64 bit Linux
RHEL4U4), I think it's clear that this code is not ready for
prime-time.
I'm backing out all the commits in the trunk/ompi/op tree from r17901
onwards. This code can be re-committed when compiles and runs on
common platforms.
cd ompi/op
svn merge -r 17907:17900 https://svn.open-mpi.org/svn/ompi/trunk/ompi/op .
This commit was SVN r17908.
The following SVN revision numbers were found above:

operations. Added to the reduction operations a set of reduction
functions that take 2 input buffers and one output buffer to avoid
some extra memory copies. These can't be used with user defined
operations. The intel c collective suite passes both original, and
new (new, not the user defined operations).

portals btl has ownership and therefor didn't free the frag as it should) this
causes leakage and hangs in MPI_Finalize.
Also added a bit more debugging.
This commit was SVN r17900.
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.
* The opal_sys_timer_get_cycles() call was implemented for
Sparc v9 using inline assembly, but not in the assembly files.
This would only currently matter on Linux Sparc systems using
a compiler that didn't support inline assembly (not many of
those), but it should be there for completion.
* The linux timer component would always build on non-Alpha
platforms, rather than only building on platforms where
opal_sys_timer_get_cycles() was implemented. This would
only matter on a very narrow set of platforms that we don't
really support, but still, it could be more right. We now
only build the component on platforms where we have the
assembly call to get the cycle counter.
* Added a comment to opal/sys/timer.h to note that the linux
timer component needed to be updated if another platform was
added.
This should be harmless to commit. It will only really change
behaviors on platforms we don't have assembly support for, which
currently won't make it through configure. It really only matters
when (if?) we support atomic operations through libatomic_ops.
