The UD BTL isn't gone - the latest version is in my afriedle-ud branch. This version on the trunk was very old, ompi_ignore'd, lacked performance, and probably contained bugs. The maintained version on my branch is working solid, and will eventually come back, but not for v1.2.
This commit was SVN r12144.
Fix the problem observed by multiple people that comm_spawned children were (once again) being mapped onto the same nodes as their parents. This was caused by going through the RAS a second time, thus overwriting the mapper's bookkeeping that told RMAPS where it had left off.
To solve this - and to continue moving forward on the ORTE development - we introduce the concept of attributes to control the behavior of the RM frameworks. I defined the attributes and a list of attributes as new ORTE data types to make it easier for people to pass them around (since they are now fundamental to the system, and therefore we will be packing and unpacking them frequently). Thus, all the functions to manipulate attributes can be implemented and debugged in one place.
I used those capabilities in two places:
1. Added an attribute list to the rmgr.spawn interface.
2. Added an attribute list to the ras.allocate interface. At the moment, the only attribute I modified the various RAS components to recognize is the USE_PARENT_ALLOCATION one (as defined in rmgr_types.h).
So the RAS components now know how to reuse an allocation. I have debugged this under rsh, but it now needs to be tested on a wider set of platforms.

* Update comments in some MPI_FILE_* functions to reflect that the
MPI specs have different page numbers in the ps and pdf (woof!).
* Update comments to say "Retain" where we meant retain (not "return)
* Add a check in MPI_ERRHANDLER_FREE to raise an MPI exception if the
user attempts to free an intrinsic errhandler *and* the refcount is
1 (meaning that it would actually free the intrinsic). This
protects erroneous programs from segv'ing.
* Remove lengthy comment from comm_get_errhandler.c which is no
longer valid (because of the MPI-2 errata that says that users *do*
have to call MPI_ERRHANDLER_FREE).

MPI::SEEK_* because iostreams (well, ios_base, but I don't think that
should be included directly) can use SEEK_* as values in an enum, which
means that 'const int' is bad for them.
* Remove now useless comments in the cxx example programs
* include iostream after mpi.h so that our examples work with other MPI
implementations that don't try to be as friendly with the constants.

* Fix MPI-2 page number in comments for a specific reference in the
spec
* Allow getting/setting the errhandler on MPI_FILE_NULL
* Allow freeing of intrinsic errhandlers, per MPI-2 errata (if you GET
an errhandler on a communicator, you must be able to FREE it, even
if it's an intrinsic).
Thanks to Lisandro Dalcin for reporting these problems.

some issues with the C #defines SEEK_{SET, END, POS}. The workaround
involves some hackery that should work in almost every common use case
for the C stdio constants (and all the legal issues of the MPI constants).
The one issue is that the C stdio constants are now const ints instead
of #defines, which means that #ifdef checks will fail for the constants.
Behavior can be disabled at either configure time or build time.

* Don't dereference the frag during alloc unless we're sure
it's not NULL

attached to a convertor if and only if we can use the optimized conversion
functions. It's a little bit broader than before (the 2 architectures
has to be identical).
This commit was SVN r11962.
First, move the OPAL_THREAD_LOCK out to the same level as its corresponding UNLOCK. It was possible to hit the UNLOCK without ever acquiring the lock.
Since the OPAL_THREAD_ADD64() is now protected by this lock, we can just do the decrement non-atomically.

Don't try to acquire ompi_request_lock here, which in all cases is already held. Avoids deadlock that occurs even when threads are enabled and we're running a THREAD_SINGLE app.

we want to decrease as much as possible the usage of these functions.
We now check not only th HOMOGENEOUS flag on the datatype or convertor, but the
bits indicating a type is in use. If a communication transfert a type having the
same representation on both peers we can use the optimized version of the conversion.
In same time we build a more accurate conversion table for each master convertor,
based on the minimum differences between the 2 architectures.

I have added a new MCA param (hey, you can't have too many!) called OMPI_MCA_orte_timing. If set to anything other than zero, the system will report out critical timing loops. At the moment, this includes three measurements:
1. Time spent going through the RDS->RAS->RMAPS, setting up triggers, etc. prior to calling the actual PLS launch function. This is reported out as time to setup job.
2. Time spent in MPI_Init from start of that function (well, right after opal_init) to the place where we send all of our info the registry. Reported out as time from start to exec_compound_cmd
3. Time actually spent executing the compound cmd. Reported out as time to exec_compound_cmd.
A few additional timing points will be added shortly.
These may eventually be removed or (better) setup with a conditional compile flag.
