The MPICH team is pleased to announce the availability of a new bug-fix release (MPICH-3.0.3). http://www.mpich.org/ A list of changes in this release is included at the end of this email. Regards, The MPICH Team =============================================================================== Changes in 3.0.3 =============================================================================== # RMA: Added a new mechanism for piggybacking RMA synchronization operations, which improves the performance of several synchronization operations, including Flush. # RMA: Added an optimization to utilize the MPI_MODE_NOCHECK assertion in passive target RMA to improve performance by eliminating a lock request message. # RMA: Added a default implementation of shared memory windows to CH3. This adds support for this MPI 3.0 feature to the ch3:sock device. # RMA: Fix a bug that resulted in an error when RMA operation request handles where completed outside of a synchronization epoch. # PM/PMI: Upgraded to hwloc-1.6.2rc1. This version uses libpciaccess instead of libpci, to workaround the GPL license used by libpci. # PM/PMI: Added support for the Cobalt process manager. # BUILD SYSTEM: allow MPI_LONG_DOUBLE_SUPPORT to be disabled with a configure option. # FORTRAN: fix MPI_WEIGHTS_EMPTY in the Fortran bindings # MISC: fix a bug in MPI_Get_elements where it could return incorrect values # Several other minor bug fixes, memory leak fixes, and code cleanup.
