The MPICH team is pleased to announce the availability of a new preview
release (mpich-3.1rc2). This is a release candidate of the upcoming MPICH
3.1, and adds several capabilities including a fully integrated source for
vanilla MPICH and the IBM PE/BG device, several improvements for the Intel
Xeon Phi architecture, improved support for fault tolerance, improvements to
MPI RMA for shared memory communication, MPI large count 64-bit safety, and
MPI Tools interface improvements. This release also fixes several bugs present
in 3.0.4.

Changes in 3.1rc2
===============================================================================
# Implement runtime compatibility with MPICH-derived impelmentations as per
the ABI Compatibility Initiative (see www.mpich.org/abi for more information).
# Integrated MPICH-PAMI code base for Blue Gene/Q and other IBM
platforms.
# Several improvements to the SCIF netmod. (code contribution from
Intel).
# Major revamp of the MPI_T interface added in MPI-3.
# Added environment variables to control a lot more capabilities for
collectives. See the README.envvar file for more information.
# Allow non-blocking collectives and fault tolerance at the same
time. The option MPIR_PARAM_ENABLE_COLL_FT_RET has been deprecated as
it is no longer necessary.
# Improvements to MPI_WIN_ALLOCATE to internally allocate shared
memory between processes on the same node.
# Performance improvements for MPI RMA operations on shared memory
for MPI_WIN_ALLOCATE and MPI_WIN_ALLOCATE_SHARED.
# Enable shared library builds by default.
# Allow non-blocking collectives and fault tolerance at the same
time. The option MPIR_PARAM_ENABLE_COLL_FT_RET has been deprecated as
it is no longer necessary.
# Improvements to MPI_WIN_ALLOCATE to internally allocate shared
memory between processes on the same node.
# Performance improvements for MPI RMA operations on shared memory
for MPI_WIN_ALLOCATE and MPI_WIN_ALLOCATE_SHARED.
# Enable shared library builds by default.
# Upgraded hwloc to 1.7.2.
# Several improvements to the Hydra-SLURM integration.
# MPICH now supports operations on very large datatypes (those that describe
more than 32 bits of data). This work also allows MPICH to fully support
MPI-3's introduction of MPI_Count.
# Several other minor bug fixes, memory leak fixes, and code cleanup.
