Per #4590, we now ''require'' the PROCEDURE keyword support in Fortran
for the mpi_f08 module. So if the Fortran compiler doesn't support
it, then we won't build the mpi_f08 module.

Junchao Zhang pointed out to me that we had the wrong parameter name
and string length specification for the "version" parameter. This
matters because Fortran allows passing by parameter name
(vs. parameter ordering). Specifically, we had the interface as:
{{{
subroutine MPI_Get_library_version_f08(name,resultlen,ierror)
character(len=MPI_MAX_PROCESSOR_NAME), intent(out) :: name
...etc.
}}}
but it should be:
{{{
subroutine MPI_Get_library_version_f08(version,resultlen,ierror)
character(len=MPI_MAX_LIBRARY_VERSION_STRING), intent(out) :: version
...etc.
}}}
Thankfully, MPI_MAX_PROCESSOR_NAME and MPI_MAX_LIBRARY_VERSION_STRING
are both 255 in OMPI, so there's no ABI issue caused by changing the
length from MMPN --> MMLVS.
The ABI is also unaffected by the parameter name change: if you
compile/link an MPI application calling MPI_GET_LIBRARY_VERSION with
1.8, it'll still run-time link with this change.
However, if an MPI program compiled using parameter name passing with
the old/incorrect parameter name ("name"), it won't be able to compile
with the new/correct parameter name ("version"). But this will only
happen for an incorrect MPI application (because the MPI-3 mandated
parameter name is "version", not "name"), so they deserve what they
get.

Since this header is included in .F90 files (which are preprocessed,
vs. .f90 files, which are *not* preprocessed), we don't want to
accidentally start C-style comments, which are recognized by some
Fortran compiler preprocessors (e.g., Absoft).
This commit was SVN r29394.
So just move the comment to the prior line, and it's all good. This
is obviosuly not *necessary*, but it helps cut down on warning noise.

BIND(C) doesn't let us have LOGICAL parameters, so we have to be

Additionally, the mpi_f08 type for MPI_Status presented some

this in much more detail.

Use proper array types for the sendtypes and recevtypes params in the
definition of these subroutines (since they're prototyped to be array
parameters in the module). See the comment in the code for a more
complete explanation.
Note that after talking to Craig Rasumussen, he says that this is
fairly common practice in the Fortran community (i.e., pass a scalar
that is part of an array to effectively pass an offset into that
array, since Fortran passes by reference). So this might be a hack,
but it's a commonly-accepted hack.

This patch reshape the way we deal with topologies completely. Where
our topologies were mainly storage components (they were not capable
of creating the new communicator), the new version is built around a
[possibly] common representation (in mca/topo/topo.h), but the functions
to attach and retrieve the topological information are specific to each
component. As a result the ompi_create_cart and ompi_create_graph functions
become useless and have been removed.
In addition to adding the internal infrastructure to manage the topology
information, it updates the MPI interface, and the debuggers support and
provides all Fortran interfaces.

* Remove 2nd overloaded interfaces for MPI_TESTALL, MPI_TESTSOME,

* 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

it was quite a bit more subtle/complex). A second commit will
follow this one to update svn:ignore values (just to ensure we

by the changed ignore values and new/changed files).

"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.

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.
