The MPICH team is pleased to announce the availability of a new preview release (mpich-3.2b1). 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, significant improvements to the MPICH Portals 4 implementation, and a completely revamped RMA infrastructure providing scalability and performance improvements. This preview release includes all the features 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, pre-init functionality, and new MPI_T routines
to look up variables by name. 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.
# Completely revamped RMA infrastructure including several
scalability improvements, performance improvements, and bug fixes.
# The Myrinet MX network module, which had a life cyle from 1.1 till
3.1.2, has now been deprecated.
# Several other minor bug fixes, memory leak fixes, and code cleanup.
