Graph Optimization

  • Add Embedding Fusion ops for CPU/GPU.
  • Optimize SmartStage performance on GPU.

Runtime Optimization

  • Executor, support cost-based and critical path ops first.
  • GPUAllocator, support CUDA malloc async allocator. (need to use >= CUDA 11.2)
  • CPUAllocator, automatically memory allocation policy generation.
  • PMEMAllocator, optimize allocator and add statistic.

Ops & Hardware Acceleration

  • Implement SparseReshape, SparseApplyAdam, SparseApplyAdagrad, SparseApplyFtrl, ApplyAdamAsync, SparseApplyAdamAsync, KvSparseApplyAdamAsync GPU kernels.
  • Optimize UnSortedSegment on CPU.
  • Upgrade OneDNN to v2.6.

IO & Dataset

  • ParquetDataset, add parquet dataset which could reduce storage and improve performance.

Model Save/Restore

  • Asynchronous restore EmbeddingVariable from checkpoint.

Serving

  • SessionGroup, highly improve QPS and RT in inference.

ModelZoo

  • Add models SimpleMultiTask, ESSM, DBMTL, MMoE, BST.

Profiler

  • Support for mapping of operators and real thread ids in timeline.

BugFix

  • Fix EmbeddingVariable core when EmbeddingVariable only has primary embedding value.
  • Fix abnormal behavior in L2-norm calculation.
  • Fix save checkpoint issue when use LevelDB in EmbeddingVariable.
  • Fix delete old checkpoint failure when use incremental checkpoint.
  • Fix build failure with CUDA 11.6.
