In an abort situation, just bail out immediately -- don't try to
invoke any atexit()/on_exit()-registered functions.
This is similar rationale to
open-mpi/ompi@17846411c3.
Ensure to define ompi/pompi versions for platforms that don't have
weak symbols. Also make fortran/mpif-h/profile build a separate
sizeof library, just like fortran/mpifh-h does.
Per http://www.open-mpi.org/community/lists/devel/2015/08/17775.php,
some compilers don't like it when there's a .f90 file that only
contains comments (and no actual Fortran code). So if OMPI determines
that the Fortran compiler does not support enough Fortran mojo to
support MPI_SIZEOF, generate at least one dummy Fortran subroutine
that can be compiled in an otherwise barren Fortran landscape that is
devoid of life and hope.
This pull request adds an arraylist of type Buffer to
the Request class. Whenever a request object is created
that has associated buffers, the buffers should be added
to this array list so the java garbage collector does
not dispose of the buffers prematurely.
This is a more robust expansion on the idea first proposed by

Portals4 supports atomic ops on datatypes less than or equal to
max_fetch_atomic_size bytes. This commit fixes a bug that required
the datatype to be less than max_fetch_atomic_size bytes.
Fortran uses objects (ompi_f08_mpi_comm_world, mpi_fortran_bottom,, ...) that are defined in C.
Some compilers have different requirements on how these objects should be aligned.
Smaller alignment in C can lead to several confusing warnings from the linker, so try to
find the alignment expected by Fortran compiler, and inform the C compiler.
The libmpi_*.la fortran libraries make some direct calls to
libopen-pal.la. In many (most?) cases, having libmpi_* link
against libmpi is sufficient (because libmpi pulls in libopen-pal).
But when building RPMs on SLES, some compiler/linker flags are used
that seem to make this implicit linking not sufficient -- we get
missing opal symbols when creating libmpi_mpifh.la. So link in
open-pal directly (vs. indirectly), which solves the problem.
On some OSs (e.g., Ubuntu 14.04.2 LTS), the linker is configured such
that the symbols of library dependencies are not available to the
application. Hence, we need to explicitly list such dependencies when
creating the executable.
For this commit, these tests are use OPAL function calls, so we must
explicitly link in libopen-pal.so.
- make the internal structure follow the Open MPI naming convention
- provide a single flag/macro which controls the compilation/utilization of this
feature, to avoid that somebody using this has to modify every single
fcoll component. A configure option could be added later if desired.
