636b42afff handle non existant recv buf in reduce for non root processes
(basic allreduce does this for mpi_in_place case)

61b8218d76 MPI_IN_PLACE fix for reduce.
(actually a work around for an optimisation in the reduce for not saving ops on the first recv of each segment)
Minor change in topo.

30af775d40 further fixes. The first hierarchical MPI_Bcast works! Its just ~ 100 times slower then basic at the moment :-)

not before.

83b5a675f9 Don't automatically take the first entry off the selected component
list; be sure to check its priority against the basic component and
take the one with the higher priority.

b17c4334c4 - Remove all vestigates of using the built-in mcb_tree from the
reduce_inorder() function -- we don't use the tree at all.
- Add more relevant "volatile"'s for the control buffers in the
  fragment mpool (and associated casts where necessary)

c7fe54ba44 - Remove some silly compiler warnings
- Move the "process 0" logic out of the main loop in reduce to make
  the code a bit less complex (at the price of slight code
  duplication, but it iss now significantly easier to read)
- Fix problem with uniquenes guarantee in the bootstrap mpool -- using
  the CID alone was not sufficient enough to guarantee uniquenes; now
  use (CID, rank 0 process name) tuple to check for uniqueness
- Made a few debugging help changes in coll_sm.h; especially helps
  debugging on uniprocessors

fcef1774d5 Per advice from Ralf W., change the pkgdata declarations in
Makefile.am's to be a *slightly* more correct (and, more importantly,
less error-prone) construct.

bc181d7130 Remove the .ompi_ignore so that everyone starts compiling this, but
lower the default priority to 0 so that it's not active unless you
specifically ask for it (this component needs more testing by people
other than me before we unleash it on the public).

15d0a95202 - Remove extra whitespace from Makefile.am's from when we removed
Makefile.options
- Sample in each of the three projects of how to link againt the
  relevant libraries so that when components are loaded into a parent
  process' space, we don't rely on the libopal/liborte/libmpi symbols
  being in the parent's public symbol namespace -- instead,
  dynamically link to the relevant libraries, allowing the dynamic
  linker to pull those libraries in at run-time, if needed

068b9c72a2 Bunches of changes
- remove redundant OBJ_CONSTRUCT in bcast
- fix up some macros in coll_sm.h
- check to ensure that if there are too many processes in the
  communicator (i.e., if we couldn't fit a flag for each of them in
  the control segment), then fail selection
- setup the in_use flags properly
- adapt to new mpool API
- first working copy of reduce -- not tree-baed (but still
  NUMA-aware), and only processes in order from process 0 to process
  N-1 -- do not have a tree-based and/or commutative version yet
  (i.e., process the results in whatever order they arrive)

Reduce now passes the new ibm reduce_big.c test.  Woo hoo!  Time to
declare success for the evening (and run the intel test tomorrow).

0fcd682c4c MPI-2 7.3.3 description of MPI_Allgatherv is wrong -- can't just have
all processes call MPI_Gatherv(MPI_IN_PLACE...) because IN_PLACE is
only allowed to be used at the root.  Non-root processes must use
their receive buf as the send buf.

5dca18f903 First cut of handling MPI_IN_PLACE:
- added relevant logic for everything except
  mca_coll_basic_reduce_log_intra() -- need some help from George /
  Edgar on this one...
- replaced ompi_ddt_sndrcv() with ompi_ddt_copy_content_same_ddt()
  where relevant
- removed some "if (size > 1)" conditionals, because the self coll
  module will always be chosen for collectives where size==1

Waiting for BA's tests to check the validity of this IN_PLACE stuff.
We'll see how it goes!
