The MPICH team is pleased to announce the availability of a new preview release (mpich-3.2a2). This preview release adds several capabilities including support for the proposed MPI-3.1 standard (contains nonblocking collective I/O), full Fortran 2008 support (enabled by default), support for the Mellanox MXM interface for InfiniBand, support for the Mellanox HCOLL interface for collective communication, support for OFED InfiniBand for Xeon and Xeon Phi architectures, and significant improvements to the MPICH/portals4 implementation. These features represent a subset of those planned for the 3.2.x release series.

===============================================================================
# Added support for proposed MPI-3.1 features including nonblocking
collective I/O, address manipulation routines, thread-safety for
MPI initialization and pre-init functionality. Proposed MPI-3.1
features are implemented as MPIX_ functions and the MPI version
number is still set to 3.0.
# Fortran 2008 bindings are enabled by default and fully supported.
# Added support for the Mellanox MXM InfiniBand interface. (thanks
to Mellanox for the code contribution).
# Added support for the Mellanox HCOLL interface for collectives.
(thanks to Mellanox for the code contribution).
# Added support for OFED IB on Xeon and Xeon Phi. (thanks to RIKEN
and University of Tokyo for the contribution).
# Significant stability improvements to the MPICH/portals4
implementation.
# Several other minor bug fixes, memory leak fixes, and code cleanup.
