new Fortran revamp a few months ago) that failed when you compiled
with "ifort -i8".
The secret: "test $foo -eq 0" fails when $foo is sufficiently large.
So instead, use "test "$foo" = "0"". expr does work with large
integers, though, so one "test -lt" was replaced with expr.

* Use proper tag space (the negatives below the blocking communicators)
instead of the point-to-point space
* Use the PML interface instead of the MPI interface, since the MPI
interface 1) shouldn't be used by components and 2) doesn't like
negative tags

Update all the orte ess components to remove their associated APIs for retrieving proc data. Update the grpcomm API to reflect transfer of set/get modex info to the db framework.
Note that this doesn't recreate the old GPR. This is strictly a local db storage that may (at some point) obtain any missing data from the local daemon as part of an async methodology. The framework allows us to experiment with such methods without perturbing the default one.

This commit was SVN r26649.
* Add new configure command line options and deprecate some old ones:
* --with-verbs replaces --with-openib
* --with-verbs-libdir replaces --with-openib-libdir
* If you specify --with-openib[-libdir] without
--with-verbs[-libdir], you'll get a "these options have been
deprecated!" warning, but then they'll act just like
--with-verbs[--libdir].
'''Sidenote:''' Note that we are not renaming any components at this
time, nor are we renaming the top-level OMPI_CHECK_OPENIB m4 macro
(which is pretty strongly tied to the openib BTL and is bastaridzed
by the ofud BTL). Note that there will likely be more changes in
this area coming soon (next week?) when some long-standing changes
move to the SVN trunk: some openib BTL infrastructure will move to
ompi/mca/common, and its configury gets split up / refactored.
We extend our philosophy of other --with-<foo> configure options of
--with-verbs to ''all'' verbs-lovin components:
* If you specify --with-verbs, then all verbs-lovin' components must
configure successfully (or abort). This currently means: OOB ud,
BTL ofud, BTL openib.
* If you specify --with-verbs=DIR, then all verbs-lovin' component
must configure successfully (or abort), and will use DIR to find
verbs headers and libraries.
* If you specify --without-verbs, then all verbs-lovin' components
will be ignored.
This commit also fixes a problem where the --with-openib=DIR form
would not use DIR for ''all'' verbs-lovin' components (I think only
BTL openib and BTL ofud used that DIR). Now all of them do, as does
hwloc (because hwloc has some !OpenFabrics helper functions that
require ibv types from verbs.h).
There's a little new m4 infrastructure worth mentioning:
* If you create a new verbs-lovin' component (i.e., a component that
need verbs), your configure.m4 should
AC_REQUIRE([OPAL_CHECK_VERBS_DIR]).
* You can then use three global shell variables: $opal_want_verbs,
$opal_verbs_dir, $opal_verbs_libdir, which will be set as follows:
* opal_want_verbs will be "yes" and opal_verbs_dir and
opal_verbs_libdir will both be set to directory values, '''OR'''
* opal_want_verbs will be "no" and opal_verbs_dir and
opal_verbs_libdir will both be set empty

1. they modified the OMPI-ORTE interface, which is something I promised to avoid doing unless absolutely necessary, and
2. the framework ident is already in the component name key provided to the modex db. What is missing is the project ident, but as Jeff and I discussed last week, we really need to add that field to the component struct anyway to avoid multi-project collisions on framework names. That will be done over the next couple of weeks as a separate effort.

helper file, even if we find that the system has <infiniband/verbs.h>.
The reason is because there are some inline functions in that verbs
helper file that invoke ibv_* functions. Some linkers (e.g., Solaris
Studio Compilers) will instantiate those static inline functions --
even if we don't use them -- and therefore we need to be able to
resolve the ibv_* symbols at link time.
But since -libverbs is only specified in places where we use other
ibv_* functions (e.g., the OpenFabrics-based BTLs), that means that
linking random executables can/will fail (e.g., orterun).
So instead, introduce a new #define: OPAL_HWLOC_WANT_VERBS_HELPER. If
this macro is set to 1 before including opal/mca/hwloc/hwloc.h, then
you'll also get the hwloc OpenFabrics verbs helper header file (*if*
hwloc found <infiniband/verbs.h> -- otherwise, it'll #error).
This commit was SVN r26417.
* Remove paffinity, maffinity, and carto frameworks -- they've been
wholly replaced by hwloc.
* Move ompi_mpi_init() affinity-setting/checking code down to ORTE.
* Update sm, smcuda, wv, and openib components to no longer use carto.
Instead, use hwloc data. There are still optimizations possible in
the sm/smcuda BTLs (i.e., making multiple mpools). Also, the old
carto-based code found out how many NUMA nodes were ''available''
-- not how many were used ''in this job''. The new hwloc-using
code computes the same value -- it was not updated to calculate how
many NUMA nodes are used ''by this job.''
* Note that I cannot compile the smcuda and wv BTLs -- I ''think''
they're right, but they need to be verified by their owners.
* The openib component now does a bunch of stuff to figure out where
"near" OpenFabrics devices are. '''THIS IS A CHANGE IN DEFAULT
BEHAVIOR!!''' and still needs to be verified by OpenFabrics vendors
(I do not have a NUMA machine with an OpenFabrics device that is a
non-uniform distance from multiple different NUMA nodes).
* Completely rewrite the OMPI_Affinity_str() routine from the
"affinity" mpiext extension. This extension now understands
hyperthreads; the output format of it has changed a bit to reflect
this new information.
* Bunches of minor changes around the code base to update names/types
from maffinity/paffinity-based names to hwloc-based names.
* Add some helper functions into the hwloc base, mainly having to do
with the fact that we have the hwloc data reporting ''all''
topology information, but sometimes you really only want the
(online | available) data.

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.

Note that the previous patch allowed the following test to -pass-:
ompi-tests/mpich_tester/mpich_pt2pt/truncmult.c
This patch makes that test -fail- due to the assumption that MPI_Wait will update the status.MPI_ERROR field. In Open MPI we do not do this, so the MPI_ERROR field being inspected will remain set to MPI_ERR_PENDING. See comments in req_wait.c for why we do this.
If we change the test to not inspect the MPI_ERROR field after calling MPI_Wait successfully, then the test would pass correctly with this patch.

MPI started!).
The FLAG argument to fortran attribute copy functions is a LOGICAL,
meaning that it can only return .TRUE. or .FALSE. The corresponding C
argument is an int, and the MPI spec says that it must return 1 or 0.
However, in Fortran, .TRUE. is not always necessarily == 1. So we
need to expand the test to see if it's a Fortran callback. If so,
check for the Fortran .TRUE. value (not 1). If it's a C callback,
then check for 1.
