===============================================================================
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.
