3.1.5 -- October, 2019
----------------------

- Fix OMPIO issue limiting file reads/writes to 2GB. Thanks to
Richard Warren for reporting the issue.
- At run time, automatically disable Linux cross-memory attach (CMA)
for vader BTL (shared memory) copies when running in user namespaces
(i.e., containers). Many thanks to Adrian Reber for raising the
issue and providing the fix.
- Sending very large MPI messages using the ofi MTL will fail with
some of the underlying Libfabric transports (e.g., PSM2 with
messages >=4GB, verbs with messages >=2GB). Prior version of Open
MPI failed silently; this version of Open MPI invokes the
appropriate MPI error handler upon failure. See
https://github.com/open-mpi/ompi/issues/7058 for more details.
Thanks to Emmanuel Thom� for raising the issue.
- Fix case where 0-extent datatypes might be eliminated during
optimization. Thanks to Github user @tjahns for raising the issue.
- Ensure that the MPIR_Breakpoint symbol is not optimized out on
problematic platforms.
- Fix MPI one-sided 32 bit atomic support.
- Fix OMPIO offset calculations with SEEK_END and SEEK_CUR in
MPI_FILE_GET_POSITION. Thanks to Wei-keng Liao for raising the
issue.
- Add "naive" regx component that will never fail, no matter how
esoteric the hostnames are.
- Fix corner case for datatype extent computations. Thanks to David
Dickenson for raising the issue.
- Allow individual jobs to set their map/rank/bind policies when
running LSF. Thanks to Nick R. Papior for assistance in solving the
issue.
- Fix MPI buffered sends with the "cm" PML.
- Properly propagate errors to avoid deadlocks in MPI one-sided operations.
- Update to PMIx v2.2.3.
- Fix data corruption in non-contiguous MPI accumulates over UCX.
- Fix ssh-based tree-based spawning at scale. Many thanks to Github
user @zrss for the report and diagnosis.
- Fix the Open MPI RPM spec file to not abort when grep fails. Thanks
to Daniel Letai for bringing this to our attention.
- Handle new SLURM CLI options (SLURM 19 deprecated some options that
Open MPI was using). Thanks to Jordan Hayes for the report and the
initial fix.
- OMPI: fix division by zero with an empty file view.
- Also handle shmat()/shmdt() memory patching with OS-bypass networks.
- Add support for unwinding info to all files that are present in the
stack starting from MPI_Init, which is helpful with parallel
debuggers. Thanks to James Clark for the report and initial fix.
- Fixed inadvertant use of bitwise operators in the MPI C++ bindings
header files. Thanks to Bert Wesarg for the report and the fix.
