== 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. This commit was SVN r26283.

Many updates and bug fixes for the Fortran bindings. Sorry these aren't separated out into individual commits; they represent a few months of work in the Mercurial branch, and it seemed error-prone to try to break them up into multiple SVN commits. * Remove 2nd overloaded interfaces for MPI_TESTALL, MPI_TESTSOME, MPI_WAITALL, and MPI_WAITSOME in the "mpi" module implementations (because we're not allowed to have them, anyway -- it causes complications in the profiling interface). This forced an MPI-2.2 errata in the MPI Forum; we applied the errata here (the array of statuses parameter could not have a specific dimension specified in the dummy argument). Fixes trac:3166. * Similarly, fix type for MPI_ARGVS_NULL in Fortran * Add MPI_3.0 function MPI_F_SYNC_REG (Fortran interfaces only). * Add MPI-3.0 MPI_MESSAGE_NO_PROC in the mpi_f08 module. * Added mpi_f08 handle comparison operators, per MPI-3.0 addendum to the F08 proposal at the last Forum meeting. * Added missing type(MPI_File) and type(Message) in mpi_f08 module. * Fix --disable-mpi-io configure switch with all Fortran interfaces * Re-factor the Fortran header files to be fundamentally simpler and easier to maintain. Fortran constant values in the header files are now generated by a script named mpif-values.pl during autogen.pl (they were previously generated by mpif-common.pl, but it was quite a bit more subtle/complex). A second commit will follow this one to update svn:ignore values (just to ensure we don't muck up the first commit with the SVN client getting confused by the changed ignore values and new/changed files). * Fix some dependencies for compile ordering in ompi/mpi/fortran/use-mpi-ignore-tkr/Makefile.am. * Fix bad wording in several places (.m4 file name, ompi_info output, etc.): we previoulsy said "F08 assumed shape" when we really meant "F08 assumed rank" (for Fortran gurus, those are very different things). * Removed the GREEK/SVN version string from mpif.h. It really had no purpose being there. Still to be done: * Handling of 2D array of strings in MPI_COMM_SPAWN_MULTIPLE still isn't right yet. Not sure how many people really care about this :-), but it is still broken. This commit was SVN r26997. The following Trac tickets were found above: Ticket 3166 --> https://svn.open-mpi.org/trac/ompi/ticket/3166
