Update to OpenMPI 1.5.3:

1.5.3
-----

- Add missing "affinity" MPI extension (i.e., the OMPI_Affinity_str()
  API) that was accidentally left out of the 1.5.2 release.


1.5.2
-----

- Replaced all custom topology / affinity code with initial support
  for hwloc v1.1.1 (PLPA has been removed -- long live hwloc!).  Note
  that hwloc is bundled with Open MPI, but an external hwloc can be
  used, if desired.  See README for more details.
- Many CMake updates for Windows builds.
- Updated opal_cr_thread_sleep_wait MCA param default value to make it
  less aggressive.
- Updated debugger support to allow Totalview attaching from jobs
  launched directly via srun (not mpirun).  Thanks to Nikolay Piskun
  for the patch.
- Added more FTB/CIFTS support.
- Fixed compile error with the PGI compiler.
- Portability fixes to allow the openib BTL to run on the Solaris
  verbs stack.
- Fixed multi-token command-line issues when using the mpirun
  --debug switch.  For example:
      mpirun --debug -np 2 a.out "foo bar"
  Thanks to Gabriele Fatigati for reporting the issue.
- Added ARM support.
- Added the MPI_ROOT environment variable in the Open MPI Linux SRPM
  for customers who use the BPS and LSF batch managers.
- Updated ROMIO from MPICH v1.3.1 (plus one additional patch).
- Fixed some deprecated MPI API function notification messages.
- Added new "bfo" PML that provides failover on OpenFabrics networks.
- Fixed some buffer memcheck issues in MPI_*_init.
- Added Solaris-specific chip detection and performance improvements.
- Fix some compile errors on Solaris.
- Updated the "rmcast" framework with bug fixes, new functionality.
- Updated the Voltaire FCA component with bug fixes, new
  functionality.  Support for FCA version 2.1.
- Fix gcc 4.4.x and 4.5.x over-aggressive warning notifications on
  possibly freeing stack variables.  Thanks to the Gentoo packagers
  for reporting the issue.
- Make the openib component be verbose when it disqualifies itself due
  to MPI_THREAD_MULTIPLE.
- Minor man page fixes.
- Various checkpoint / restart fixes.
- Fix race condition in the one-sided unlock code.  Thanks to
  Guillaume Thouvenin for finding the issue.
- Improve help message aggregation.
- Add OMPI_Affinity_str() optional user-level API function (i.e., the
  "affinity" MPI extension).  See README for more details.
- Added btl_tcp_if_seq MCA parameter to select a different ethernet
  interface for each MPI process on a node.  This parameter is only
  useful when used with virtual ethernet interfaces on a single
  network card (e.g., when using virtual interfaces give dedicated
  hardware resources on the NIC to each process).
- Changed behavior of mpirun to terminate if it receives 10 (or more)
  SIGPIPEs.
- Fixed oversubscription detection.
- Added new mtl_mx_board and mtl_mx_endpoint MCA parameters.
- Added ummunotify support for OpenFabrics-based transports.  See the
  README for more details.
