In libfabric v1.0.0 (i.e., API v1.0), the usnic provider handled
FI_MSG_PREFIX inconsistently between sends and receives. This has
been fixed in libfabric v1.1.0 (i.e., API v1.1): FI_MSG_PREFIX is
handled consistently for both sends and receives.
Run-time detect which libfabric we are running with and adapt behavior
appropriately.
Handle the differences between libfabric v1.0.0 and v1.1.0 in the
return value of fi_cq_readerr().
Also consolidate CRC and truncation errors into the same handling
block, since truncation errors are typically another symptom of CRC
errors. This ensures that buffers get reposted properly.
Instead of silently determining that the usnic BTL can't be built,
announce that usnic is checking for libfabric support, and then
AC_MSG_RESULT the result of that check.
@ggouaillardet is likely offline for the weekend, but master is broken
on RHEL 6.5 systems that do not have MOFED installed. So I'm taking
the liberty of revering this commit; I'm guessing Gilles will fixup
and re-commit next week.
This reverts commit 77f8282d51.
since ibv_create_xrc_rcv_qp is now deprecated, and in order to
be "future-proof", we have to consider the case in which only XRC Domains are supported.
Thanks Paul Hargrove for the detailled report.
@ggouaillardet was right -- we should have put the
ompi_buffer_detach_f08() function in the use-mpi-f08 directory to
begin with. Putting it in the mpif-h directory made it complicated as
to whether the function would be built or not (e.g., whether weak
symbols were supported or not, whether the profiling layer was
disabled or not, ...etc.).
Just put it in the use-mpi-f08 directory and always build it (when the
mpi_f08 module is built, of course), and keep it simple.
Since there is no profiling version of the f08 buffer_detach function
(or, more specifically, the Fortran compile does the name mangling of
MPI and PMPI to the back-end C function for us), ensure that it is
only compiled once.
Also, per Gilles' observation, the f08-related #pragmas are no longer
relevant.
Add an mpi_f08-specific implementation for MPI_BUFFER_DETACH.
Per MPI-3.1:3.6, p45, the buffer argument is ignored in
MPI_BUFFER_DETACH for mpif.h and the mpi module. But in the mpi_f08
module, the buffer argument is treated like it is in the C binding.
When you "autogen.pl --no-ompi", the AC_SIZEOF(bool) test is not run.
But we *do* run AC_SIZEOF(_Bool), which is the equivalent. So switch
the uses of SIZEOF_BOOL in the code base to be SIZEOF__BOOL, and it's
all good.
PGI was failing to build this test due to the {} initializers of some
of the global variables. The initializers were added to remove common
symbols from the test repository. This commit removes the initializers
and makes the variables static which should fix both the compile issue
and avoid the common symbols.
This commit additionally removes the check for
OPAL_ENABLE_MULTI_THREADS since Open MPI requires thread support.
