Highlights

  • Add MKL-DNN Int8 support, especially for VNNI acceleration support. Low precision inference accelerates both latency and throughput significantly
  • Add support for runnning MKL-BLAS models under MKL-DNN. We leverage MKL-DNN to speed up both training and inference for MKL-BLAS models
  • Add Spark 2.4 support. Our examples and APIs are fully compatible with Spark 2.4, we released the binary for Spark 2.4 together with other Spark versions
