What problem does it solve?
CUDA kernel development and benchmarking guidance for NVIDIA GPUs used with HuggingFace diffusers and transformers. It helps practitioners design, implement, and benchmark custom CUDA kernels, compare against baseline implementations, and integrate with the HuggingFace Kernels Hub for loading pre-compiled kernels on H100, A100, and T4.
Core Features & Use Cases
- Core kernel patterns (RMSNorm, RoPE, GEGLU, AdaLN) for diffusion models and LLMs.
- Benchmarking workflows to compare optimized kernels against baseline PyTorch implementations, including end-to-end video generation and micro-benchmarks.
- Hub integration and diffusers/transformers integration patterns to load and apply external kernels with minimal code changes.
- Use Case: Designers debugging kernel performance or building custom CUDA ops for diffusers pipelines and transformer models.
Quick Start
Run the end-to-end and RMSNorm benchmarks to compare optimized kernels against baseline implementations.
