The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 1.1.3. This release is mainly a bug fix release over the the v1.1.2 release. Version 1.1.3 can be downloaded from the main Open MPI web site or any of its mirrors (mirrors will be updating shortly).

We strongly recommend that all users upgrade to version 1.1.3 if possible.

Here are a list of changes in v1.1.3 as compared to v1.1.2:

- Fixed 64-bit alignment issues with TCP interface detection on
  intel-based OS X machines.
- Adjusted TCP interface selection to automatically ignore Linux
  channel-bonded slave interfaces.
- Fixed the type of the first parameter to the MPI F90 binding for
  MPI_INITIALIZED.  Thanks to Tim Campbell for pointing out the
- Fix a bunch of places in the Fortran MPI bindings where (MPI_Fint*)
  was mistakenly being used instead of (MPI_Aint*).
- Fixes for fortran MPI_STARTALL, which could sometimes return
  incorrect request values.  Thanks to Tim Campbell for pointing out
  the problem.
- Include both pre- and post-MPI-2 errata bindings for
- Fix math error on Intel OS X platforms that would greatly increase
  shared memory latency.
- Fix type casting issue with MPI_ERRCODES_IGNORE that would cause
  errors when using a C++ compiler.  Thanks to Barry Smith for
  bringing this to our attention.
- Fix possible segmentation fault during shutdown when using the
- Remove the "hierarch" coll component; it was not intended to be
  included in stable releases yet.
- Fix a race condition with stdout/stderr not appearing properly from
  all processes upon termination of an MPI job.
- Fix internal accounting errors with the self BTL.
- Fix typos in the code path for when sizeof(int) != sizeof(INTEGER)
  in the MPI F77 bindings functions.  Thanks to Pierre-Matthieu
  Anglade for bringing this problem to our attention.
- Fix for a memory leak in the derived datatype function
  ompi_ddt_duplicate().  Thanks to Andreas Schafer for reporting,
  diagnosing, and patching the leak.
- Used better performing basic algorithm for MPI_ALLGATHERV.
- Added a workaround for a bug in the Intel 9.1 C++ compiler (all
  versions up to and including 20060925) in the MPI C++ bindings that
  caused run-time failures.  Thanks to Scott Weitzenkamp for reporting
  this problem.
- Fix MPI_SIZEOF implementation in the F90 bindings for COMPLEX
  variable types.
- Fixes for persistent requests involving MPI_PROC_NULL.  Thanks to
  Lisandro Dalcin for reporting the problem.
- Fixes to MPI_TEST* and MPI_WAIT* for proper MPI exception reporting.
  Thanks to Lisandro Dalcin for finding the issue.
- Various fixes for MPI generalized request handling; addition of
  missing MPI::Grequest functionality to the C++ bindings.
- Add "mpi_preconnect_all" MCA parameter to force wireup of all MPI
  connections during MPI_INIT (vs. making connections lazily whenever
  the first MPI communication occurs between a pair of peers).
- Fix a problem for when $FC and/or $F77 were specified as multiple
  tokens.  Thanks to Orion Poplawski for identifying the problem and
  to Ralf Wildenhues for suggesting the fix.
  with respect to what arguments they allowed and the behavior that
  they effected.  Thanks to Lisandro Dalcin for reporting the
