934caaf449 Fix at least one segv; use the right number of segments (i.e., the
number o segments in the fragment pool, not in the bootstrap pool)

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).

ed56e743b7 * update configure.ac to use the modern version of AC_INIT and
AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
  number to be set at autoconf time (instead of at configure time, as
  it was before).  Set the version number, minus the subversion r number,
  at autoconf time.  Override the internal variables to include the r
  number (if needed) at configure time.  Basically, the right thing
  should always happen.  The only place it might not is the version
  reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
  them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
  in the directory containing source files, even if the Makefile.am is
  in another directory.  This should start making it feasible to
  reduce the number of Makefile.am files we have in the tree, which
  will greatly reduce the time to run autogen and configure.

7bab4ed269 bunches of updates
- finally added "in use" flags -- one flag protects a set of segments
- these flags now used in bcast to protect (for example) when a
  message is so long that the root loops around the segments and has
  to re-use old segments -- now it knows that it has to wait until the
  non-root processes have finished with that set of segments before it
  can start using them
- implement allreduce as a reduce followed by a bcast (per discussion
  with rich)
- removed some redundant data on various data structures
- implemented query MCA param ("coll_sm_shared_mem_used_data") that
  tells you how much shared memory will be used for a given set of MCA
  params (e.g., number of segments, etc.).  For example:

  ompi_info --mca coll_sm_info_num_procs 4 --param coll sm | \
	    grep shared_mem_used_data

  tells you that for the default MCA param values (as of r7172), for 4
  processes, sm will use 548864 bytes of shared memory for its data
  transfer section
- remove a bunch of .c files from the Makefile.am that aren't
  implemented yet (i.e., all they do is return ERR_NOT_IMPLEMENTED)

Now on to the big Altix to test that this stuff really works...

bc72a7722b Updates:
- bcast now works properly for root!=0 and multi-fragment messages
- destroy mpool when communicator is destroyed
Still need to implement:
- "in use" flags for groups of fragments so that "wrapping around" in
  the data segment doesn't overwrite not-yet-read data
- ensure that shared memory isn't removed before all processes have
  finished with it (e.g., during COMM_FREE)

much time) and somewhat-lame implementation of barrier (need to
precompute some more stuff rather than calculate it every time).

f41e4149fa - Add new mpool base function: lookup by module name. This allows
multiple components to share a single mpool module (e.g., the
  ptl/btl and coll sm components).
- Re-tool the ptl, btl, and coll sm components to first look for the
  target mpool module, and if they don't find it, to create it.
- coll sm component now correctly identifies when it is supposed to
  run or not (i.e., if all the processes in the communicator are on
  the same host).  Now we just need to fill in some algorithms.  :-)

ba99409628 Major simplifications to component versioning:
- After long discussions and ruminations on how we run components in
  LAM/MPI, made the decision that, by default, all components included
  in Open MPI will use the version number of their parent project
  (i.e., OMPI or ORTE).  They are certaint free to use a different
  number, but this simplification makes the common cases easy:
  - components are only released when the parent project is released
  - it is easy (trivial?) to distinguish which version component goes
    with with version of the parent project
- removed all autogen/configure code for templating the version .h
  file in components
- made all ORTE components use ORTE_*_VERSION for version numbers
- made all OMPI components use OMPI_*_VERSION for version numbers
- removed all VERSION files from components
- configure now displays OPAL, ORTE, and OMPI version numbers
- ditto for ompi_info
- right now, faking it -- OPAL and ORTE and OMPI will always have the
  same version number (i.e., they all come from the same top-level
  VERSION file).  But this paves the way for the Great Configure
  Reorganization, where, among other things, each project will have
  its own version number.

So all in all, we went from a boatload of version numbers to
[effectively] three.  That's pretty good.  :-)
