The MPICH team is pleased to announce the availability of a new preview
release (mpich-3.1b1). This preview release is the first in a new major
version series in 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, and improvements to MPI RMA for shared
memory communication. This release also fixes several bugs present in
3.0.4.

===============================================================================
Changes in 3.1b1
===============================================================================
# Integrated MPICH-PAMI code base for Blue Gene/Q and other IBM
platforms.
# Several improvements to the SCIF netmod. (code contribution from
Intel).
# 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 removed as
it is no longer necessary.
# Improvements to MPI_WIN_ALLOCATE to internally allocate shared
memory between processes on the same node (the "alloc_shm" info
argument needs to be provided).
# Enable shared library builds by default.
# Upgraded hwloc to 1.7.1.
# Several improvements to the Hydra-SLURM integration.
# Several other minor bug fixes, memory leak fixes, and code cleanup.
