cuPilot: A Strategy-Coordinated Multi-agent Framework for CUDA Kernel Evolution
cuPilot introduces a strategy-coordinated multi-agent framework for optimizing CUDA kernels. It addresses limitations of existing evolution frameworks (crossover representation, fitness, population initialization) by using strategy as an intermediate semantic representation. Key features include a Strategy-Coordinated Evolution (SCE) algorithm, roofline-guided prompting, and strategy-level population initialization. It achieves an average speedup of 3.09x over PyTorch on 100 kernels and showcases sophisticated optimizations with high hardware utilization on GEMM tasks.

Optimizing CUDA kernels is labor-intensive due to hardware-software co-design complexity and proprietary libraries. Existing LLM-based solutions often fall short due to suboptimal agent designs and mismatched evolution representations (crossover, fitness, population initialization), leading to suboptimal performance and premature convergence. cuPilot addresses these by introducing strategy as an intermediate semantic representation.
cuPilot proposes a strategy-coordinated multi-agent framework. The Strategy-Coordinated Evolution (SCE) algorithm decouples reasoning into strategy-level crossover and strategy-to-kernel translation. Roofline-guided prompting directs LLM optimization based on whether the kernel is compute-bound or memory-bound. Strategy-level population initialization uses an external strategy pool and RAG to learn from historical data, improving convergence.
cuPilot achieves an average speedup of 3.09x over PyTorch on Kernelbench, with up to 4.06x speedup on GEMM tasks. Ablation studies confirm the effectiveness of roofline-guided prompting (44.2% latency reduction) and strategy-level population initialization (54.1% latency reduction). Case studies on GEMM highlight sophisticated optimizations like Tensor Cores, padding, layout swizzling, and double buffering.
