oneCCL Bindings for Pytorch* v2.1.400+xpu release note

Uplift oneCCL to 2021.13.1 release version in v2.1.400+xpu release.

Intel® oneCCL Bindings for Pytorch* v2.1.300+xpu release note

Features include:

• Extend a prototype feature enabled by TORCH_LLM_ALLREDUCE=1 to provide better scale-up performance by enabling optimized collectives such as allreduce, allgather, reducescatter algorithms in Intel® oneCCL. This feature requires XeLink enabled for cross-cards communication.
• Enable a set of coalesced primitives in CCL backend, including allreduce_into_tensor_coalesced, allgather_into_tensor_coalesced , reduce_scatter_tensor_coalesced and _broadcast_coalesced.

oneCCL Bindings for Pytorch* v2.1.200+xpu release note

Features include:

• Uplift oneCCL to 2021.12 release version.
• LLM inference scaling optimization based on oneCCL (Prototype)
  • Export CCL_SKIP_SCHEDULER=1 to enable the optimization

oneCCL Bindings for Pytorch* v2.2.0+cpu release note

1. Update oneCCL to 2021.9
2. Align to the PyTorch 2.2.0

oneCCL Bindings for Pytorch* v2.1.100+xpu release note

Features include:

• Add experimental allreduce implementation to provide better allreduce performance especially in LLM inference. This experimental feature can be enabled by TORCH_LLM_ALLREDUCE=1 and can speed up single node performance with up to 4 Intel® Data Center GPU Max 1550 cards (requires XeLink enabled for cross-cards communication).

• Uplift oneCCL to 2021.11.1 release version.

• Uplift supported PyTorch version to 2.1.0.
