2.0.0 -- 12 July 2016

**********************************************************************

* Open MPI is now fully MPI-3.1 compliant

|

- Enhancements to reduce the memory footprint for jobs at scale. A
|
||||
new MCA parameter, "mpi_add_procs_cutoff", is available to set the
|
||||
threshold for using this feature.
|
||||
Major new features:
|
||||
|
||||
- Many enhancements to MPI RMA. Open MPI now maps MPI RMA operations
|
||||
on to native RMA operations for those networks which support this
|
||||
capability.
|
||||
- Greatly improved support for MPI_THREAD_MULTIPLE (when configured
|
||||
with --enable-mpi-thread-multiple).

- Enhancements to reduce the memory footprint for jobs at scale. A
|
||||
new MCA parameter, "mpi_add_procs_cutoff", is available to set the
|
||||
threshold for using this feature.
|
||||
- Completely revamped support for memory registration hooks when using
|
||||
OS-bypass network transports.
|
||||
- Significant OMPIO performance improvements and many bug fixes.
|
||||
- Add support for PMIx - Process Management Interface for Exascale.
|
||||
Version 1.1.2 of PMIx is included internally in this release.
|
||||
- Add support for PLFS file systems in Open MPI I/O.
|
||||
- Add support for UCX transport.
|
||||
- Simplify build process for Cray XC systems. Add support for
|
||||
using native SLURM.
|
||||
- Add a --tune mpirun command line option to simplify setting many
|
||||
environment variables and MCA parameters.
|
||||
- Add a new MCA parameter "orte_default_dash_host" to offer an analogue
|
||||
to the existing "orte_default_hostfile" MCA parameter.
|
||||
- Add the ability to specify the number of desired slots in the mpirun
|
||||
--host option.
|
||||
|
||||
Changes in behavior compared to prior versions:
|
||||
|
||||
- In environments where mpirun cannot automatically determine the
|
||||
number of slots available (e.g., when using a hostfile that does not
|
||||
specify "slots", or when using --host without specifying a ":N"
|
||||
suffix to hostnames), mpirun now requires the use of "-np N" to
|
||||
specify how many MPI processes to launch.
|
||||
- The MPI C++ bindings -- which were removed from the MPI standard in
|
||||
v3.0 -- are no longer built by default and will be removed in some
|
||||
future version of Open MPI. Use the --enable-mpi-cxx-bindings
|
||||
@ -87,37 +252,26 @@ Master (not on release branches yet)
|
||||
- ompi_info now shows all components, even if they do not have MCA
|
||||
parameters. The prettyprint output now separates groups with a
|
||||
dashed line.
|
||||
- Add support for PMIx - Process Management Interface for Exascale.
|
||||
Version 1.1.2 of PMIx is included internally in this release.
|
||||
- Add support for PLFS file systems in Open MPI I/O.
|
||||
- Add support for UCX transport.
|
||||
- Improved support for MPI_THREAD_MULTIPLE (when configured with
|
||||
--enable-mpi-thread-multiple).
|
||||
- Simplify build process for Cray XC systems. Add support for
|
||||
using native SLURM.
|
||||
- Updated internal/embedded copies of third-part software:
|
||||
- Update the internal copy of ROMIO to that which shipped in MPICH
|
||||
3.1.4.
|
||||
- Update internal copy of libevent to v2.0.22.
|
||||
- Update internal copy of hwloc to v1.11.2.
|
||||
- Add a --tune mpirun command line option to simplify setting many
|
||||
environment variables and MCA parameters.
|
||||
- Add a new MCA parameter -
|
||||
"opal_common_verbs_want_fork_support". This replaces the
|
||||
"btl_openib_want_fork_support" parameter.
|
||||
- Add a new MCA parameter "orte_default_dash_host" to offer an analogue
|
||||
to the existing "orte_default_hostfile" MCA parameter.
|
||||
- Add --with-platform-patches-dir configure option.
|
||||
- Add --with-pmi-libdir configure option for environments that install
|
||||
PMI libs in a non-default location.
|
||||
- Add the ability to specify the number of desired slots in the mpirun
|
||||
--host option.
|
||||
- In environments where mpirun cannot automatically determine the
|
||||
number of slots available (e.g., when using a hostfile that does not
|
||||
specify "slots", or when using --host without specifying a ":N"
|
||||
suffix to hostnames), mpirun now requires the use of "-np N" to
|
||||
specify how many MPI processes to launch.
|
||||
- Removed some legacy support:
|
||||
- OMPIO is now the default implementation of parallel I/O, with the
|
||||
exception for Lustre parallel filesystems (where ROMIO is still the
|
||||
default). The default selection of OMPI vs. ROMIO can be controlled
|
||||
via the "--mca io ompi|romio" command line switch to mpirun.
|
||||
- Per Open MPI's versioning scheme (see the README), increasing the
|
||||
major version number to 2 indicates that this version is not
|
||||
ABI-compatible with prior versions of Open MPI. You will need to
|
||||
recompile MPI and OpenSHMEM applications to work with this version
|
||||
of Open MPI.
|
||||
- Removed checkpoint/restart code due to loss of maintainer. :-(
|
||||
- Change the behavior for handling certain signals when using PSM and
|
||||
PSM2 libraries. Previously, the PSM and PSM2 libraries would trap
|
||||
certain signals in order to generate tracebacks. The mechanism was
|
||||
found to cause issues with Open MPI's own error reporting mechanism.
|
||||
If not already set, Open MPI now sets the IPATH_NO_BACKTRACE and
|
||||
HFI_NO_BACKTRACE environment variables to disable PSM/PSM2's
|
||||
handling these signals.
|
||||
|
||||
Removed legacy support:
|
||||
|
||||
- Removed support for OS X Leopard.
|

- Removed support for Cray XT systems.

- Removed VampirTrace.
