After a simple search-replace, the Portals4 description actually
described Portals3. This commit replaces the Portals3 description
with a Portals4 description.
Thanks to Paul Hargrove for spotting this and supplying the patch.
Embedding libltdl without the use of Libtool bootstrapping has
proven... difficult. Instead, create a new simple "dl" framework. It
only provides 4 functions:
- open a DSO (very similar to lt_dlopenadvise())
- lookup a symbol in a previously-opened DSO (very similar to lt_dlsym())
- close a previously-opened DSO (very similar to lt_dlclose())
- iterate over all files in a directory (very similar to ld_dlforeachfile())
There will be follow-on commits with a simple dlopen-based component
(nowhere near as complete/functional as libltdl, but good enough for
Linux and OS X), and a libltdl-based component for all other
platforms.
The intent is that the dlopen-based component can be built by default
in almost all cases. But if libltdl is available, that component will
be built. End result: we still get DSO-based functionality by default
in (almost?) all cases. Without embedding libltdl. Which is what we
want.
Remove sections of README concerning Cray that are no longer
relevant owing to being obsolete. Minor grammar fixes.
Clarification of the --with-pmi section, as this works
differently for Cray systems.
This commit was SVN r32819.
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).

implementation does (that is not quite adherant to the Fortran
standard). If a compiler allows this behavior, build the mpi_f08
wrapper. For example, ifort allows it, but Pathscale/EKOPath 5.0 is
stricter in its Fortran compliance and disallows it.
This test is temporary; the real fix is to make OMPI adhere to Fortran
properly (i.e., see #4157). Once we fix#4157, this test should be
removed. The main reason for committing this test is to put it into
v1.7.4 so that we can release, but with the intent to remove it by
1.7.5 (or 1.8.x at the latest!).

Each Fortran bindings layer builds on the other. Specifically:
* You can build just mpif.h support
* You can build mpif.h and "use mpi" support
* You can build mpif.h and "use mpi" and "use mpi_f08" support
You cannot build mpif.h and "use mpi_f08" support without also
building "use mpi" support.
This new functionality adds new capabilities to the existing
--enable-fortran-mpi switch. You can now pass the following values:
* --enable-fortran-mpi=no or none: synonyms for --disable-fortran-mpi
(i.e., build no Fortran bindings).
* --enable-fortran-mpi=mpifh: build only mpif.h support
* --enable-fortran-mpi=usempi: build mpif.h and "use mpi" support
* --enable-fortran-mpi=usempif08: build mpif.h, "use mpi", and "use
mpi_f08" support
* --enable-fortran-mpi=yes or all: synonyms for --enable-fortran-mpi
(i.e., no argument), which will attempt to build all 3 Fortran
bindings
