It is also targeted to provide optimized support for modern platforms (CPU, GPU, and interconnects) for HPC, Deep Learning, Machine Learning, Big Data and Data Science applications.

The major features and enhancements available in MVAPICH-Plus 4.0rc 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
    - CUDA-aware MPI (pt2pt and collective) support
