Sender can receive and complete PUT request before it gets completion on the first rndv packet. senreq struct may be reused for the next MPI_Send and unexpected completion mess up the things. I sometimes got SEGV and sometimes data corruption.

are 3 arguments: the pointer to the memory location to prefetch, the type of
operation that will be done on the memory (read or write) and the expected
locality.

lower_bound is now directly added to the user pointer when the convertor
is created, instead of having to add it all over the places inside the
pack/unpack functions.

* Change the type of Fortan's MPI_STATUSES_IGNORE to double complex
so that it will never possibly be mistaken for a real status (i.e.,
integer(MPI_STATUS_SIZE)), particularly in the F90 bindings. See
comment in mpif-common.h explaining this (analogous argument to
MPI_ARGVS_NULL for MPI_COMM_SPAWN_MULTIPLE).
* Add second interfaces for the following functions that take a double
complex (i.e., MPI_STATUSES_IGNORE). This required adding the second
interface in mpi-f90-interfaces.h[.sh] and then generating new wrapper
functions to call the back-end F77 function for each of these four, so
we added 4 new files in ompi/mpi/f90/scripts/ and updated the various
Makefile.am's to match:
* MPI_TESTALL
* MPI_TESTSOME
* MPI_WAITALL
* MPI_WAITSOME
The XSL is now not in sync with the scripts. Although I suppose that
that is becoming less and less important (because it does not impact
the end user at all -- to be 100% explicit, no release should ever be
held up because the XSL is out of sync), but it will probably be
important when we go to fix the "large" interface; so it's still worth
fixing... for now...

mpirun/orterun now has an option to print the version number. If -V/--version
is given, it will print the version number. If it's the only option, we
exit cleanly. Otherwise, we continue on as if --version wasn't given
(except we've printed the version number).

UD is the Unreliable Datagram transport for Infiniband, specifically OpenIB. This BTL is derived from the existing openib BTL, which is RC (Reliable Connection) based.
Still a work in progress, as there is a lot of work left to do. Specifically, performance, scalability, and flow control need to be addressed.
Currently I'm playing around with different methods for handling receive buffers, as well as profiling to figure out where the time is going.

the cases. Instead replace it with a better solution, which work even for
fragments received not in order. However, this solution work only on the
current supported modes in ompi (homogeneous & heterogeneous with endianess).
The method is tricky. We will rely on 2 partial unpacks. First we will find
a byte that is not on the data to unpack, and we will pad the data with this
byte. Once we have the full length as expected, we will unpack the data, and
all the bytes in the unpacked form which do not match the unused byte will be
copied into the user buffer. This way we will reconstruct the unpacked data
in 2 times, once for the begining and once for the end.

they will be contiguous even when a multiple of them are send. This is the difference
between the NO_GAPS and CONTIGUOUS flags: contiguous one suppose that the data might
have gaps in the begining and/or at the end but the content of the data is contiguous.

pack is if the data has the BASIC flag which means it is predefined and contiguous.
For the unpack the convertor has to be homogeneous plus the same requirements
as for the pack.

1. Changed the RMGR and PLS APIs to add "signal_job" and "signal_proc" entry points. Only the "signal_job" entries are implemented - none of the components have implementations for "signal_proc" at this time. Thus, you can signal all of the procs in a job, but cannot currently signal only one specific proc.
2. Implemented those new API functions in all components except xgrid (Brian will do so very soon). Only the rsh/ssh and fork modules have been tested, however, and only under OS-X.
3. Added signal traps and callback functions for SIGUSR1/2 to orterun/mpirun that catch those signals and call the appropriate commands to propagate them out to all processes in the job.
4. Added a new test directory under the orte branch to (eventually) hold unit and system level tests for just the run-time. Since our test branch of the repository is under restricted access, people working on the RTE were continually developing their own system-level tests - thus making it hard to help diagnose problems. I have moved the more commonly-used functions here, and added one specifically for testing the SIGUSR1/2 functionality.
I will be contacting people directly to seek help with testing the changes on more environments. Other than compile issues, you should see absolutely no change in behavior on any of your systems - this additional functionality is transparent to anyone who does not issue a SIGUSR1/2 to mpirun.

1) don't need tree if memory is just malloc'd
2) fix memory and free list leak..
3) deregister first and then free... doh..
This commit was SVN r10251.
Added a tree to track memory allocation from MPI_Alloc_mem, this allows us to
free the registrations in a sane fashion.. also should be faster..
This commit was SVN r10248.
