[mvapich-discuss] Announcing the release of MVAPICH2-X 2.3rc3

[Subramoni, Hari]

The MVAPICH team is pleased to announce the release of MVAPICH2-X 2.3rc3 (with
support for advanced MPI Features, OSU INAM, and Hybrid MPI+PGAS).

MVAPICH2-X 2.3rc3 provides support for advanced MPI features/support (XPMEM,
enhanced asynchronous progress design, User Mode Memory Registration (UMR),
Dynamically Connected (DC) transport protocol, Scalable Reliable Datagram (SRD)
transport protocol, SHARP and Data Partitioning-based Multi-Leader Design (DPML)
for MPI collectives, XPMEM-based collectives, Contention Aware Kernel-Assisted
MPI collectives, and Non-blocking Collectives with Core-Direct and SHARP), 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.

* Features and Enhancements (since 2.3rc2):

    - MPI Features
        - Based on MVAPICH2 2.3.3
            - OFA-IB-CH3, OFA-IB-RoCE, PSM-CH3, and PSM2-CH3 interfaces
    - Enhanced point-to-point and collective tunings for Fulhame at EPCC,
      Catalyst at EPCC, Mayer at Sandia, Auzre at Microsoft, and Frontera at TACC

    - MPI (Advanced) Features
        - Improved performance for communication using DC transport
            -  OFA-IB-CH3 interface
        - Add support for AWS EFA adapter and SRD transport protocol
            -  OFA-IB-CH3 interface
        - Add point-to-point and collective tuning for AWS EFA adapter and SRD
          transport protocol
            -  OFA-IB-CH3 interface
        - Add improved Allgatherv algorithm for small messages
            - OFA-IB-CH3, OFA-IB-RoCE, PSM-CH3, and PSM2-CH3 interfaces
        - Tuning for XPMEM-based MPI collective operations for Intel
          Broadwell, Intel CascadeLake, Azure HB (AMD EPYC), and Azure HC (Intel
          Skylake) systems
            - OFA-IB-CH3, OFA-IB-RoCE, PSM-CH3, and PSM2-CH3 interfaces

    - Support for OSU InfiniBand Network Analysis and Management (OSU INAM)

    - Unified Runtime Features
        - Based on MVAPICH2 2.3.3 (OFA-IB-CH3 interface). All the runtime
          features enabled by default in OFA-IB-CH3 and OFA-IB-RoCE interface
          of MVAPICH2 2.3.3 are available in MVAPICH2-X 2.3rc3

* Bug Fixes (since 2.3rc2):
    - Fix various compilation warnings and memory leaks
