This is the master version of @ggouaillardet's patch from
open-mpi/ompi-release#148 (there was a minor conflict to fix and
several fuzzings of line numbers).
As noted by Alexander Pozdneev, non-blocking sends are now able to
*access* buffers in pending non-blocking send operations; the buffers
just can't be *modified*.
Using the underlying hardware identification to split
communicators based on locality has been enabled using
the MPI_Comm_Split_Type function.
Currently implemented split's are:
HWTHREAD
CORE
L1CACHE
L2CACHE
L3CACHE
SOCKET
NUMA
NODE
BOARD
HOST
CU
CLUSTER
However only NODE is defined in the standard which is why the
remaning splits are referred to using the OMPI_ prefix instead
of the standard MPI_ prefix.
I have tested this using --without-hwloc and --with-hwloc=<path>
which both give the same output.
NOTE: I think something fishy is going on in the locality operators.
In my test-program I couldn't get the correct split on these requests:
NUMA, SOCKET, L3CACHE
where I suspected a full communicator but only got one.
Per discussion starting
http://www.open-mpi.org/community/lists/users/2014/12/26018.php, at
least note that OMPI does not allow adding or deleting attributes in
an attribute copy or delete callback (or any of its children) on the
same object on which the callback was invoked.
Add MPI_Ibarrier.3in to reference MPI_Barrier.3, and update
MPI_Barrier.3in to include bindings for MPI_Ibarrier. Slightly update
the text to be inclusive of the non-blocking case.
Fixes#242.
Update the VERSION file scheme:
* Remove "want_repo_rev".
* Add "tarball_version".
All values are now always included (major, minor, release, greek,
repo_rev). However, configure.ac now runs "opal_get_version.sh
... --tarball", which will return the value of tarball_version (if it
is non-empty) or the "full" version string (i.e.,
"major.minor.releasegreek").
MTT found that the addition of the MPI_SIZEOF interfaces to mpif.h was
causing a linker error with the Absoft compiler. Absoft is working on
a fix, but we can workaround the issue for now. See comment in
Makefile.am in this commit for a lengthy explanation.

gfortran 4.8 does not support storage_size() on all relevant types
that we need. So add a configure test to check and see if the
compiler's storage_size() intrinsic supports enough types for us to do
MPI_SIZEOF.
Also remove an accidentally redundant check for fortran INTERFACE.

What started as a simple ticket ended up reaching the way up to the
MPI Forum.
It turns out that we are supposed to have MPI_SIZEOF for all Fortran
interfaces: mpif.h, the mpi module, and the mpi_f08 module.
It further turns out that to properly support MPI_SIZEOF, your Fortran
compiler *has* support the INTERFACE keyword and ISO_FORTRAN_ENV. We
can't use "ignore TKR" functionality, because the whole point of
MPI_SIZEOF is that the implementation knows what type was passed to it
("ignore TKR" functionality, by definition, throws that information
away). Hence, we have to have an MPI_SIZEOF interface+implementation
for all intrinsic types, kinds, and ranks.
This commit therefore adds a perl script that generates both the
interfaces and implementations for MPI_SIZEOF in each of mpif.h, the
mpi module, and mpi_f08 module (yay consolidation!).
The perl script uses the results of some new configure tests:
* check if the Fortran compiler supports the INTERFACE keyword
* check if the Fortran compiler supports ISO_FORTRAN_ENV
* find the max array rank (i.e., dimension) that the compiler supports
If the Fortran compiler supports both INTERFACE and ISO_FORTRAN_ENV,
then we'll build the MPI_SIZEOF interfaces. If not, we'll skip
MPI_SIZEOF in mpif.h and the mpi module. Note that we won't build the
mpi_f08 module -- to include the MPI_SIZEOF interfaces -- if the
Fortran compiler doesn't support INTERFACE, ISO_FORTRAN_ENV, and a
whole bunch of ther modern Fortran stuff.
Since MPI_SIZEOF interfaces are now generated by the perl script, this
commit also removes all the old MPI_SIZEOF implementations (which were
laden with a zillion #if blocks).

As noted in the comments of these files, they aren't used. Instead,
the Fortran interfaces for WTICK/WTIME just BIND(C) invoke the
back-end C functions (yay BIND(C)!). Hence, there's no need to keep
these old wrapper files around any more.

This fixes some duplicate symbols, once the .o files for the modules
were restored into the library (some compilers need the .o files, some
don't (!)).
Also, remove trailing whitespace. :-)

WHAT: Open our low-level communication infrastructure by moving all necessary components (btl/rcache/allocator/mpool) down in OPAL
All the components required for inter-process communications are currently deeply integrated in the OMPI layer. Several groups/institutions have express interest in having a more generic communication infrastructure, without all the OMPI layer dependencies. This communication layer should be made available at a different software level, available to all layers in the Open MPI software stack. As an example, our ORTE layer could replace the current OOB and instead use the BTL directly, gaining access to more reactive network interfaces than TCP. Similarly, external software libraries could take advantage of our highly optimized AM (active message) communication layer for their own purpose. UTK with support from Sandia, developped a version of Open MPI where the entire communication infrastucture has been moved down to OPAL (btl/rcache/allocator/mpool). Most of the moved components have been updated to match the new schema, with few exceptions (mainly BTLs where I have no way of compiling/testing them). Thus, the completion of this RFC is tied to being able to completing this move for all BTLs. For this we need help from the rest of the Open MPI community, especially those supporting some of the BTLs. A non-exhaustive list of BTLs that qualify here is: mx, portals4, scif, udapl, ugni, usnic.

Fix a copy-n-paste error: the ompi/pompi interfaces should not have
optional ierror arguments. Optional ierror arguments are only used in
the MPI_<foo> interfaces. The ompi/pompi interfaces are the actual
underlying routines (in C, incidentally, which is why they're declared
as BIND(C)), and do not have optional ierror arguments.
Also fix a typo in the BIND(C) name for pompi_win_shared_query_f().
