PROFILE

Qihqi

Worked across AI-Hypercomputer/torchprime and vllm-project/tpu-inference to deliver distributed training, model parallelism, and cross-framework interoperability for deep learning workflows. Refactored core modules to enable sharding-aware attention and feed-forward layers, supporting scalable multi-device execution using PyTorch and JAX. Integrated transformer-based models, including a recommender system and Stable Diffusion, while establishing conventions for model registration and CI coverage. Enhanced onboarding and developer experience through detailed documentation, including gRPC usage and PyTorch-JAX integration guides. Addressed deployment reliability in mlcommons/inference by resolving containerization issues, and maintained a focus on reproducibility, benchmarking, and maintainability throughout the development process.

Monthly summary for 2025-08 (vllm-project/tpu-inference): The primary delivery this month was Model Parallelism for Embedding and LM Head weights, enabling weight sharding across multiple devices in line with upstream practices. A new set of shard functions was added to VocabParallelEmbedding and ParallelLMHead to ensure consistent GPU sharding behavior across the embedding and language model head layers. This work lays the foundation for scalable multi-device inference and training with large models. Commit eb6123824584df3a1e14f945c0074e4ac7315583 (#607).
