[Panda, Dhabaleswar]

The MVAPICH team is pleased to announce the release of MVAPICH-Plus
4.1GA.

The new MVAPICH-Plus series is an advanced version of the MVAPICH MPI
library.  It is targeted to support unified MVAPICH2-GDR and
MVAPICH2-X features. 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 4.1GA
are as follows:

* Features and Enhancements (since 4.0)
    - Based on MPICH-4.3.0 and ABI compatible with MPICH-4.3.0
    - Added support for adaptive dynamic collective tuning
        - Performed on the fly at runtime for both CPU and GPU
    - Enhanced GPU tuning support
    - Optimized HIP kernel-based collective performance for AMD GPUs
    - Optimized algorithms for GPU Allreduce
        - GPU aware RSA, RD, Direct, and Ring algorithms
    - Optimized direct-throttling algorithms for GPU Allgather,
          Allgatherv, and Reduce-Scatter
    - Optimized ring algorithm for GPU Reduce-Scatter
    - Added support for dynamic GPU initialization after MPI_Init
    - Added support for unified GPU memory models for AMD MI300A APUs
    - Improved rndv protocol performance in point-to-point operations
    - Improved MPIT PVAR support

* Bug Fixes (since 4.0)
    - Fixed pointer caching for ROCM 6
    - Fixed memory leaks
    - Fixed issues with GPU binding in UCX enabled builds
    - Added small message fallback support to compression algorithms
    - Fixed potential memory overflow on NVIDIA GPUs
