[mvapich-discuss] Announcing the release of MVAPICH2-Virt 2.1 GA

[Panda, Dhabaleswar]

The MVAPICH team is pleased to announce the release of MVAPICH2-Virt
2.1 GA, which targets virtualization-based 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) and OpenStack. For an InfiniBand
SR-IOV-based virtualized environment, 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 over SR-IOV enabled InfiniBand
clusters. MVAPICH2-Virt 2.1 GA is based on the standard MVAPICH2 2.1
GA release.

Features for MVAPICH2-Virt 2.1 GA are listed here.

* Features
    - Based on MVAPICH2 2.1 GA
    - Support for efficient MPI communication over SR-IOV enabled
      InfiniBand networks
    - High-performance and locality-aware MPI communication with IVSHMEM
    - Support for auto-detection of IVSHMEM device in virtual machines
    - Automatic communication channel selection among SR-IOV, IVSHMEM,
      and CMA/LiMIC2
    - Supprt for integration with OpenStack
    - Support for easy configuration through runtime parameters
    - Tested with
       - Mellanox InfiniBand adapters (ConnectX-3 (56Gbps))
       - OpenStack Juno

* Bug-Fixes (since 2.1rc2):
    - Fix CMA usability check in VM environment
    - Fix an issue with getpid during init
    - Fix an issue in On-demand CM finalize

MVAPICH2-Virt 2.1 GA release requires the following software to be
installed on your system:

  - Mellanox InfiniBand adapters and OFED with SR-IOV support
  - KVM + QEMU-1.7.0 (with IVSHMEM)
  - (optional) OpenStack Juno
