Objectives

• Auto distributed LLM inference config optimization

Key Results

• [4/10] Understand the possibility/challenges in LLM inference compute graph arrangement automatically
• [0/10] Trace vLLM compute graph and data flow
• [3/10] Implement a minimal Rust inference framework
• [1/10] Define the IR for automatic optimization
• [5/10] Profile different parallelism setup with real trace and analysis their difference
• [0/10] Meta-analysis for the theory maximum improvement with heterogenous setup [offtrack]

Last Week

• [KR1] Learn about how vLLM implements the DBO. Check the feasibility to apply an execution flow automatically with a generated config.
• [misc] Write a paper commentary for SOSP.

Next Week

• Summary the optimizations in Qwen.
• Profile model's different stage (module), analyze the overlap status.
