[mvapich-discuss] Announcing the release of MVAPICH2-X 2.2 GA and OMB 5.3.2

[Panda, Dhabaleswar]

The MVAPICH team is pleased to announce the release of MVAPICH2-X 2.2
GA (Advanced MPI Features, Support for OSU INAM and Hybrid MPI+PGAS
(OpenSHMEM, UPC, CAF and UPC++) with Unified Communication Runtime),
and OSU Micro-Benchmarks (OMB) 5.3.2.

MVAPICH2-X 2.2 GA provides support for advanced MPI features
(Dynamically Connected (DC) transport protocol, User Mode Memory
Registration, On-Demand Paging (ODP) and Non-blocking Collectives with
Core-Direct), OSU INAM and hybrid MPI+PGAS (UPC, OpenSHMEM, CAF, and
UPC++) programming models with unified communication runtime for
emerging exascale systems. This library also provides flexibility for
users to write applications using the following programming models
with a unified communication runtime: MPI, MPI+OpenMP, pure UPC, pure
OpenSHMEM, pure UPC++, and pure CAF programs as well as hybrid
MPI(+OpenMP) + PGAS (UPC, OpenSHMEM, CAF, and UPC++) programs.
