What problem does it solve?
This Skill solves the challenge of running long, error-prone GPU kernel optimization experiments by enforcing a finite state machine workflow with persistent state, validation gates, and autonomous resume support.
Core Features & Use Cases
- FSM-Driven Tuning Control: Manages GPU kernel optimization through structured states including profiling, ideation, implementation, measurement, decision, and storage.
- Experiment Reliability Guardrails: Uses state files, validation scripts, idea deduplication, checkpoints, and compaction summaries to prevent skipped steps and repeated experiments.
- Use Case: Optimize sparse GEMM kernels on NVIDIA Hopper GPUs by continuously testing data-driven improvements from current best kernels or from scratch baselines while preserving progress across sessions.
Quick Start
Use the fsm-engine skill to start a CroqTuner GPU kernel optimization run from the best existing kernel for the specified shape and data type.
