problems (i.e., don't return a value from a void() function!). Thanks
to Eugene for identifying these issues. Hopefully this will fix up
the problems Oracle is having with compiling the new Fortran stuff.
This commit was SVN r26310.
the case where we have a really ancient Fortran compiler that does not
support ISO_C_BINDING, but need to test to be sure that the new
configury works.
This commit was SVN r26290.
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.

prototyping new MPI functionality. The C++ bindings are officially
deprecated, and are (currently) 1 vote away from being removed from
MPI-3 altogether. So let's whack the C++ stuff from mpiext.
This commit was SVN r26239.
If the profiling directory is present '/profile' then wire in the profiling stuff.
Only supports C and F77 (and kinda F90) at the moment.
This commit was SVN r26237.
OMPI supports multiple different repository systems (SVN, hg, git).
But the VERSION file has listed "want_svn" and "svn_r" as fields, even
though the actual repo system and version may not be SVN.
So search/replace those fields (and derrivative values that come from
those fields) with "want_repo_rev" and "repo_rev", respectively.

`autogen.pl` to properly handle all Sun Fortran version strings.
This commit was SVN r24080.
The following SVN revision numbers were found above:
r24076 --> open-mpi/ompi@ca0b0efada
Note: the ompi_check_libfca.m4 file had to be modified to avoid it stomping on global CPPFLAGS and the like. The file was also relocated to the ompi/config directory as it pertains solely to an ompi-layer component.
Forgive the mid-day configure change, but I know Shiqing is working the windows issues and don't want to cause him unnecessary redo work.
This commit was SVN r23966.
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.

MPI_INIT and start of MPI_FINALIZE.
* Clean up MPI Extensions build system to acknowledge that OMPI's the only
project with extensions, as well as remove some build artifacts necessary
for more general components.

Increase the required versions of AM, AC, and LT:
* Autoconf: 2.65
* Automake: 1.11.1
* Libtool: 2.2.6b
And therefore removed a bunch of patches that we used to apply to make
older versions of these tools work.
Also updated the HACKING document to match these version numbers,
specifically mentioned Mercurial in a few places, and removed some
outdated language about running autogen.sh in subdirectories.
This commit was SVN r22896.
error if the file-based dloader (e.g., dlopen) fails to load a DSO for
a complex reason (e.g., unresolved symbol).
This has been widely reported upstream to the libltdl maintainers - a
general solution is difficult. This is very definitely an
OMPI-specific solution. Since our embedded libltdl is hidden behind
visibility flags, that's ok.
Note that this is a change to autogen.sh, but this commit does not
force re-running autogen.sh. You'll just get the new functionality
the next time you re-run autogen.sh.
This commit was SVN r22806.
continuation mark in column 6 is enough to split the lines, we do
the same continuation mark in column 73.
Now, while that would fit any msg., this would produce warnings when
including mpif-config.h with -Wall in gfortran and -warn in ifort.
Just get the SVN Version string short and forget it. Let's see
make check choke on that.
This additionally fixes the HG version string...
(Will mention this in ticket #2259)
This commit was SVN r22620.
* Fix typo in echo message
* Only traverse into orte/ and ompi/ if they exist (i.e., properly
handle --no-orte and --no-ompi tarballs). Note that this was only
a minor error -- before, they just output error messages and
(correctly) kept going. This fix just removes the error messages.
This commit was SVN r22353.
