English(EN) Formalizing PTX in Lean to Prove GPU Kernel Correctness

在Lean中形式化GPU内核以实现深度学习的正确性

研究人员开发了一种方法,通过在Lean证明助手(Lean proof assistant)中对并行线程执行(PTX)进行建模,来形式化验证深度学习中使用的GPU内核的正确性。该方法能够对常见的GPU内核模式进行数学推理,包括获取-释放语义(acquire-release semantics)、张量核(tensor cores)和异步操作(asynchronous operations)。该团队成功地使用此框架证明了WGMMA GEMM内核、FlashAttention以及多内核专家混合(MoE)流水线的实现是正确的。 AI

影响 这种形式化验证方法可以提高GPU上深度学习计算的可靠性和效率。

    在 Lean 中形式化 PTX 以证明 GPU 内核的正确性

    We present an approach to mathematically formalizing PTX, an approach that allows modeling and reasoning about patterns common in GPU kernels for Deep Learning, including acquire-release, tensor cores, proxies, async operations, multi-kernel pipelines and data-dependent control f…
