PROFILE

Xiaoshuang Liu

Worked on the dentiny/ray repository over three months, focusing on scalable device management, flexible data processing, and distributed system enhancements. Delivered an improved hardware accelerator discovery pipeline for Ascend NPUs, expanding detection to support large multi-NPU nodes and strengthening test coverage for high-card deployments. Enhanced the dataset.filter API by enabling constructor arguments for callable filters, increasing flexibility and reusability in Python-based data pipelines. Introduced custom accelerator support for Ray LLM scheduling by updating resource management logic to handle non-GPU devices, aligning with heterogeneous hardware needs. The work emphasized robust system programming, API design, and distributed resource orchestration for production environments.

March 2025: Delivered custom accelerator support for Ray LLM scheduling in the dentiny/ray repository by introducing resources_per_bundle to configure non-GPU devices (e.g., NPUs) and updating the scheduler to honor custom resources. This aligns with heterogeneous hardware deployments and enables more efficient LLM workload placement. Commit 360ede3d5b7125467ebc93a13e66ddd5873be7b3 under PR [llm] ray.llm support custom accelerators (#51359).
