SparseOperationKit Release Notes

The release notes for SparseOperationKit.

What’s new in Version 2.0.0

  • The official release of SOK:

    • Remove the legacy code,DistributedEmbedding and All2AllDenseEmbedding will be deprecated.

    • from sparse_operation_kit import experiment as sok is replaced by import sparse_operation_kit as sok.

    • sok.DynamicVariable supports Merlin-HKV as its backend.

    • The parallel dump and load are added.

What’s new in Version 1.1.4

  • Add sok.experiment module to integrate hugectr 3G embedding:

    • Add sok.experiment.lookup_sparse, which support distributed and fused embedding lookup.

    • Add sok.experiment.DynamicVariable, whose size can grow dynamically when doing lookup.

    • See API Docs -> Experiment to get other function of sok.experiment

What’s new in Version 1.1.3

  • Update pip install instruction and fix some bugs.

What’s new in Version 1.1.2

  • Add TensorFlow Functional API support

What’s new in Version 1.1.1

  • Add Auto-Mixed-Precision training support

  • Add uint32 key dtype support

  • Add TensorFlow initializers support

  • Add DLRM benchmark results

What’s new in Version 1.1.0

  • Supports TensorFlow 1.15.

  • Supports configuring visible devices via tf.config.set_visible_devices.

  • Added a dedicated CUDA stream for SOK’s Ops.

  • Supports pip installation.

  • Fixed hanging issue in tf.distribute.MirroredStrategy when TensorFlow version greater than 2.4.

What’s new in Version 1.0.1

  • Supports Horovod as the synchronized training communication tool.

  • Supports dynamic input in All2AllDenseEmbedding, which means unique->lookup->gather pattern can be used.

  • Supports IdentityHashtable, which means no hash-mapping during inserting new keys.

  • Added TF Distributed Embedding totally with TF’s ops.

What’s new in Version 1.0.0

  • Implemented a new framework that can be used to easily integrate different embedding algorithms to common DL frameworks.

  • Supports single-node & multi-node synchronized training with TensorFlow.

  • Integrated HugeCTR’s DistributedSparseEmbedding algorithm.

  • Integrated All2AllDenseEmbedding algorithm.

  • Added custom Adam optimizer for SOK when TF version <= 2.4.
