The MPICH team is pleased to announce the availability of a new bug-fix release (mpich-3.0.4). This release adds several performance features for the Hydra process manager, support for communicator-specific tuning of eager/rendezvous thresholds, and fixes several bugs present in 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 3.0.4 =============================================================================== # BUILD SYSTEM: Reordered the default compiler search to prefer Intel and PG compilers over GNU compilers because of the performance difference. WARNING: If you do not explicitly specify the compiler you want through CC and friends, this might break ABI for you relative to the previous 3.0.x release. # OVERALL: Added support to manage per-communicator eager-rendezvous thresholds. # PM/PMI: Performance improvements to the Hydra process manager on large-scale systems by allowing for key/value caching. # Several other minor bug fixes, memory leak fixes, and code cleanup.
