Highlights

Note: BigDL v2.3.0 has been updated to include functional and security updates. Users should update to the latest version.

Nano

• Enhanced trace and quantization process (for PyTorch and TensorFlow model optimizations)
• New inference optimization methods (including Intel ARC series GPU support, CPU fp16, JIT int8, etc.)
• New inference/training features (including TorchCCL support, async inference pipeline, compressed model saving, automatic channels_last_3d, multi-instance training for customized TF train loop, etc.)
• Performance enhancement and overhead reduction for inference optimized model
• More user-friendly document and API design

Orca:

• Step-by-step distributed TensorFlow and PyTorch tutorials for different data inputs.
• Improvement and examples for distributed MMCV pipelines.
• Further enhancement for Orca Estimator (more flexible PyTorch train loops via Hook, improved multi-output prediction, memory optimization for OpenVINO, etc.)

Chronos

• 70% latency reduction for Forecasters
• New bigdl.chronos.aiops module for AIOps use case on top of Chronos algorithms.
• Enhanced TF-based TCNForecaster to better accuracy

Friesian:

• Automatic deployment of RecSys serving pipeline on Kubernetes with Helm Chart

PPML

• TDX (both VM and CoCo) support for Big Data, DL Training & Serving (including TDX-VM orchestration & k8s deployment, TDXCC installation & deployment, attestation and key management support, etc.)
• New Trusted Machine Learning toolkit (with secure and distributed SparkML & LightGBM support)
• Trusted Big Data toolkit upgrade (>2x EPC usage reduction, Apache Flink support, Azure MAA support, multi-KMS support, etc.)
• Trusted Deep Learning toolkit upgrade (with improved performance using BigDL Nano, tcmalloc, etc.)
• Trusted DL Serving toolkit upgrade (with Torch Serve, TF-Serving, and improved throughput and latency)
