runtime code goes through one of the rte, dpm, or pubsub frameworks.

There is a linking issue on Mac OSX that needs to be addressed before this is able to come back into the trunk.

8d161af059 Move hwloc_cpuset_t prettyprint routines down into the hwloc base:
* opal_hwloc_base_cset2str(): Make a human-readable string of a
   hwloc_cpuset_t (e.g., socket 2[core 3[hwt 1]])
 * opal_hwloc_base_cset2mapstr(): Make a map-like string of a
   hwloc_cpuset_t (e.g., [B./..])

2ba10c37fe Per RFC, bring in the following changes:
* Remove paffinity, maffinity, and carto frameworks -- they've been
   wholly replaced by hwloc.
 * Move ompi_mpi_init() affinity-setting/checking code down to ORTE.
 * Update sm, smcuda, wv, and openib components to no longer use carto.
   Instead, use hwloc data.  There are still optimizations possible in
   the sm/smcuda BTLs (i.e., making multiple mpools).  Also, the old
   carto-based code found out how many NUMA nodes were ''available''
   -- not how many were used ''in this job''.  The new hwloc-using
   code computes the same value -- it was not updated to calculate how
   many NUMA nodes are used ''by this job.''
   * Note that I cannot compile the smcuda and wv BTLs -- I ''think''
     they're right, but they need to be verified by their owners.
 * The openib component now does a bunch of stuff to figure out where
   "near" OpenFabrics devices are.  '''THIS IS A CHANGE IN DEFAULT
   BEHAVIOR!!''' and still needs to be verified by OpenFabrics vendors
   (I do not have a NUMA machine with an OpenFabrics device that is a
   non-uniform distance from multiple different NUMA nodes).
 * Completely rewrite the OMPI_Affinity_str() routine from the
   "affinity" mpiext extension.  This extension now understands
   hyperthreads; the output format of it has changed a bit to reflect
   this new information.
 * Bunches of minor changes around the code base to update names/types
   from maffinity/paffinity-based names to hwloc-based names.
 * Add some helper functions into the hwloc base, mainly having to do
   with the fact that we have the hwloc data reporting ''all''
   topology information, but sometimes you really only want the
   (online | available) data.

253444c6d0 == Highlights ==
1. New mpifort wrapper compiler: you can utilize mpif.h, use mpi, and use mpi_f08 through this one wrapper compiler
 1. mpif77 and mpif90 still exist, but are sym links to mpifort and may be removed in a future release
 1. The mpi module has been re-implemented and is significantly "mo' bettah"
 1. The mpi_f08 module offers many, many improvements over mpif.h and the mpi module

This stuff is coming from a VERY long-lived mercurial branch (3 years!); it'll almost certainly take a few SVN commits and a bunch of testing before I get it correctly committed to the SVN trunk.

== More details ==

Craig Rasmussen and I have been working with the MPI-3 Fortran WG and Fortran J3 committees for a long, long time to make a prototype MPI-3 Fortran bindings implementation.  We think we're at a stable enough state to bring this stuff back to the trunk, with the goal of including it in OMPI v1.7.  

Special thanks go out to everyone who has been incredibly patient and helpful to us in this journey:

 * Rolf Rabenseifner/HLRS (mastermind/genius behind the entire MPI-3 Fortran effort)
 * The Fortran J3 committee
 * Tobias Burnus/gfortran
 * Tony !Goetz/Absoft
 * Terry !Donte/Oracle
 * ...and probably others whom I'm forgetting :-(

There's still opportunities for optimization in the mpi_f08 implementation, but by and large, it is as far along as it can be until Fortran compilers start implementing the new F08 dimension(..) syntax.

Note that gfortran is currently unsupported for the mpi_f08 module and the new mpi module.  gfortran users will a) fall back to the same mpi module implementation that is in OMPI v1.5.x, and b) not get the new mpi_f08 module.  The gfortran maintainers are actively working hard to add the necessary features to support both the new mpi_f08 module and the new mpi module implementations.  This will take some time.

As mentioned above, ompi/mpi/f77 and ompi/mpi/f90 no longer exist.  All the fortran bindings implementations have been collated under ompi/mpi/fortran; each implementation has its own subdirectory:

{{{
ompi/mpi/fortran/
  base/               - glue code
  mpif-h/             - what used to be ompi/mpi/f77
  use-mpi-tkr/        - what used to be ompi/mpi/f90
  use-mpi-ignore-tkr/ - new mpi module implementation
  use-mpi-f08/        - new mpi_f08 module implementation
}}}

There's also a prototype 6-function-MPI implementation under use-mpi-f08-desc that emulates the new F08 dimension(..) syntax that isn't fully available in Fortran compilers yet.  We did that to prove it to ourselves that it could be done once the compilers fully support it.  This directory/implementation will likely eventually replace the use-mpi-f08 version.

Other things that were done:

 * ompi_info grew a few new output fields to describe what level of Fortran support is included
 * Existing Fortran examples in examples/ were renamed; new mpi_f08 examples were added
 * The old Fortran MPI libraries were renamed:
   * libmpi_f77 -> libmpi_mpifh
   * libmpi_f90 -> libmpi_usempi
 * The configury for Fortran was consolidated and significantly slimmed down.  Note that the F77 env variable is now IGNORED for configure; you should only use FC. Example:
{{{
shell$ ./configure CC=icc CXX=icpc FC=ifort ...
}}}

All of this work was done in a Mercurial branch off the SVN trunk, and hosted at Bitbucket.  This branch has got to be one of OMPI's longest-running branches.  Its first commit was Tue Apr 07 23:01:46 2009 -0400 -- it's over 3 years old!  :-)  We think we've pulled in all relevant changes from the OMPI trunk (e.g., Fortran implementations of the new MPI-3 MPROBE stuff for mpif.h, use mpi, and use mpi_f08, and the recent Fujitsu Fortran patches).

I anticipate some instability when we bring this stuff into the trunk, simply because it touches a LOT of code in the MPI layer in the OMPI code base.  We'll try our best to make it as pain-free as possible, but please bear with us when it is committed.

40a2bfa238 WARNING: Work on the temp branch being merged here encountered problems with bugs in subversion. Considerable effort has gone into validating the branch. However, not all conditions can be checked, so users are cautioned that it may be advisable to not update from the trunk for a few days to allow MTT to identify platform-specific issues.
This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change.

Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation.

  for more general components.

359464a144 Add an "affinity" Open MPI extension (also describe the
--enable-mpi-ext configure switch in the top-level README file).

See Josh's excellent wiki page about OMPI extensions:

    https://svn.open-mpi.org/trac/ompi/wiki/MPIExtensions

This extension exposes a new API to MPI applications: 

{{{
int OMPI_Affinity_str(char ompi_bound[OMPI_AFFINITY_STRING_MAX],
                      char current_binding[OMPI_AFFINITY_STRING_MAX],
                      char exists[OMPI_AFFINITY_STRING_MAX]);
}}}

It returns 3 things.  Each are a prettyprint string describing sets of
processors in terms of sockets and cores:

 1. What Open MPI bound this process to.  If Open MPI didn't bind this
    process, the prettyprint string says so.
 1. What this process is currently bound to.  If the process is
    unbound, the prettyprint string says so.  This string is a
    separate OUT parameter to detect the case where some other entity
    bound the process (potentially after Open MPI bound it).
 1. What processors are availabile in the system, mainly for reference.
