Objectives

  • Auto LLM inference config tuner

Key Results

  • [9/10] Build the first version auto tuner system
  • [7/10] Check the current situation of parallelism config optimization
  • [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

  • Refine the story. Focus on heterogenous workloads are classified by labels or input length, which is not enough. We should define a classification method through the grouping of similar performance under the same config.
  • Prepare slides to summarize the story and what to do next.
  • Prepare slides for IPADS group meeting.

Next Week

  • Run benchmark for current workload classification to prove different classes need different configs to max the goodput.
