Worked on the jeejeelee/vllm repository to enhance CPU-side attention mechanisms and improve CI validation for multimodal models. Developed an optimized Grouped Query Attention workflow that enables decoding with non-divisible batches, introducing dynamic workload scheduling and adaptive GQA usage based on query token counts to boost throughput and CPU utilization. Later, integrated Qwen2.5-VL multimodal tests into the CPU CI pipeline, aligning test mechanics with platform constraints and updating Buildkite configuration for broader test coverage. Leveraged Python, C++, and YAML to implement algorithmic improvements and robust CI/CD processes, resulting in faster inference, more reliable validation, and streamlined model serving workflows.
