Learning, Machine Learning, Big Data and Data Science applications.

The major features and enhancements available in MVAPICH-Plus 4.0 GA
are as follows:

    - Based on MPICH 4.3.0a1
    - Supports all features of MPI 4.1 standard
    - Includes enhanced OFI provider for IB systems, "mverbs;ofi_ucr"
    - Support for
        * Major CPUs (x86-Intel, x86-AMD, and ARM)
        * Major Interconnects (IB, Slingshot, OPX, Omni-Path, ROCE,
                              and Ethernet/ iWARP)
        * Major GPUs (from NVIDIA, AMD, and Intel)
    - Optimized support for pt2pt inter-node and intra-node communication
    - CMA support for intra-node pt2pt operations
    - Optimized algorithms for collectives
