middle of a struct). Now we properly define and name the union
outside the struct and simply create an instance of it inside the
struct.

support SEND_IN_PLACE causes badness because the BTL tries to use the
not-exactly-complete convertor. Don't need it in this situation anyway.

Implementation passed intel: MPI_Reduce_c , MPI_Reduce_loc_c, and MPI_Reduce_user_c tests
over TCP, BTL MX, and MTL MX, as well as, mpi_test_suite Reduce tests (up to 64 nodes).
The algorithm is still not activated by decision function (will be in the near future).

the dispatch function opal_atomic_cmpset_acq_xx was used to call
opal_atomic_cmpset_acq_32 would cause the compiler / linker to fix up a
jump address to be itself, leading to an infinite loop.
We're still looking into exactly what caused this, but during the
investigation into the hang, we determined that the compiler (both pathcc
and gcc) weren't always inlining both the call to opal_atomic_cmpset_acq_xx
and opal_atomic_cmpset_acq_32, meaning there was a function call in
opal_atomic_lock. The atomic lock will always be 32 bit, so there's no
need for the dispatch function, so might as well remove the dispatch
function that may or may not be inlined.
A bug fix that leads to potentially better performance. Gotta love the
few times that happens...

to flush all writes pending (ie, the data being protected) out of the memory
manager before we write the spinlock unlock. Only need a wmb instead of
full mb, which is at least slightly less intrusive. Also, after much
thought, no need for a memory barrier in init.

its bigger than the timeout for the connect() call, just don't register
the handler by default and fall back to connect() timing out. Should give
much happier performance on big clusters.

buffer fails. If cb is already allocated, but it is full and allocation of
additional cb fails, we spin waiting for receiver to free space in existing

* Update exactly how we handle MPI exceptions, particularly with
respect to MPI-1 section 3.2.5, and how error handlers are only
invoked for the ''first'' request that generates an exception.
* Update the "see also" section to be consistent across all 8
MPI_Test* and MPI_Wait* functions.
* Fixes trac:560

adding new procs that the remote proc's pml is the same as our local pml.
Turns the hangs from mismatched PMLs into an abort, which is better,
I think.

Adjust the RMAPS mapped_node object to propagate the required launch_id info now included in the ras_node object. This provides support for those few systems that don't use nodename to launch, but instead want some id (typically an index into the array of allocated nodes). This value gets set for each node in the RAS - the RMAPS just propagates it for easy launch.

- only include binaries for ppc/i386 -- no need for 64 bit
- default to not printing load errors so that the XGrid pls
doesn't cause errors when doing 64 bit builds

open MTL MX and BTL MX and initialize them at the same time. The problem is
that both call mx_init and mx_finalize, solution is to add an external entity
that does the init and finalize (based on ref counting).
