[mvapich-discuss] Announcing the release of MVAPICH2-Virt 2.2 GA

[Panda, Dhabaleswar]

The MVAPICH team is pleased to announce the release of MVAPICH2-Virt
2.2 GA, which targets virtual machine-based and container-based
(Docker and Singularity) HPC cloud computing environments with
InfiniBand, SR-IOV, and OpenStack.

MVAPICH2-Virt incorporates designs that take advantage of the new
features and mechanisms of high-performance networking technologies
with SR-IOV as well as other virtualization technologies such as
Inter-VM Shared Memory (IVSHMEM), IPC enabled Inter-Container Shared
Memory (IPC-SHM), Cross Memory Attach (CMA), and OpenStack.

For SR-IOV-enabled InfiniBand virtual machine environments and
InfiniBand-based container environments, MVAPICH2-Virt has very little
overhead compared to MVAPICH2 running over InfiniBand in native mode.

MVAPICH2-Virt delivers the best performance and scalability to MPI
applications running inside both virtual machines and containers over
SR-IOV enabled InfiniBand clusters.

* Features and Enhancements (since MVAPICH2-Virt 2.2 rc1):
    - Based on MVAPICH2 2.2 GA
    - Support for Singularity Container Technology
    - Tested with
      - Singularity development branch
      - Mellanox InfiniBand adapters (ConnectX-4)

* Bug-Fixes (since MVAPICH2-Virt 2.2rc1):
    - Fix a buffer overflow issue

The complete set of features for MVAPICH2-Virt 2.2 GA (since
MVAPICH2-Virt 2.1 GA) are listed here.

    - Based on MVAPICH2 2.2 GA
    - Support for efficient MPI communication over SR-IOV enabled
      InfiniBand networks
    - High-performance and locality-aware MPI communication with IVSHMEM
      for virtual machines
    - High-performance and locality-aware MPI communication with IPC-SHM
      and CMA for containers
    - Support for auto-detection of IVSHMEM device in virtual machines
    - Support for locality auto-detection in containers
    - Automatic communication channel selection among SR-IOV, IVSHMEM, and
      CMA/LiMIC2 in virtual machines
    - Automatic communication channel selection among IPC-SHM, CMA, and
      HCA in containers
    - Support for both Docker and Singularity Container Technologies
    - Support for integration with OpenStack
    - Support for easy configuration through runtime parameters
    - Tested with
        - Docker 1.9.1 and 1.10.3
        - Singularity development branch
        - Mellanox InfiniBand adapters (ConnectX-3 and ConnectX-4)
        - OpenStack Juno
