Highlights

Note: BigDL v2.2.0 has been updated to include functional and security updates. Users should update to the latest version.

  • Nano
    • Extend BigDL Nano inference to support iGPU and more data types (INT8/BF16/FP16 quantization)
    • More performance features (e.g., InferenceOptimizer for Keras, Nano decorator for PyTorch training loop, Nano Context Manager for thread number control and autocast, etc.)
    • Support installation with more PyTorch/TensorFlow versions and conditional dependencies on different platforms
  • PPML
    • Upgrade BigDL PPML solution to support new LibOS (e.g., Gramine1.3.1, Occlum0.29.2) with better security, higher performance, more stability and easier deployment.
    • Support more Big Data frameworks (Spark 3.1.3, Flink, Hive etc.), more Python and Data Science tools (Numpy, Pandas, sklearn, Torch Serv, Triton, Flask etc.), and distributed DL training using Orca
