DataKernelBench: Can LLMs Optimize Database Queries on GPUs?

DataKernelBench evaluates whether large language models (LLMs) can optimize database queries for GPU execution. The benchmark translates SQL into PyTorch TorchPlan programs and tests LLMs on optimizing core tensor snippets or full queries in CUDA or Triton, using execution-guided repair. On TPC‑H SF10 with an H100 GPU, the best full‑query CUDA configuration outperforms torch.compile by 2.11×, and extending TorchPlan with Dask‑cuDF enables a 2.54× speedup on TPC‑H SF100 across four H100 GPUs.

Kernel Forge: An Agent Harness for LLM-based Generation and Optimization of CUDA Kernels

arXiv:2607. 24762v1 Announce Type: new Abstract: Machine learning models are increasingly embedded in everyday software, and most of their runtime is spent in a small set of compute kernels such as matrix multiplication, convolution, and normalization.

PTXBench: Benchmark and Adapt LLMs for GPU Kernel Optimization with Architecture-specific PTX

PTXBench is a benchmark designed to evaluate and adapt large language models (LLMs) for GPU kernel optimization using architecture-specific PTX code. It assesses functional correctness, runtime execution of target instructions, and speedup over leading libraries on GEMM and attention workloads on H100 and B200 GPUs. The study finds uneven performance across models, especially on complex attention backward tasks, and shows that fine‑tuning Qwen3.6‑27B improves some tasks but generalization remains inconsistent.
