Project description

Manually optimized kernels (e.g., flash attention) are critical for the performance of LLM inference and training. However, most of these kernels have typically been carefully optimized for a specific GPU platform and may pose a serious obstacle to the portability of LLM applications. Consequently, to achieve high-performance on different GPUs, LLM kernels need to be re-implemented or manually re-optimized.

Open AI Triton (

https://github.com/triton-lang/triton)

has recently emerged as a promising open-source alternative to writing custom CUDA kernels. It enables one to write kernels for execution on GPUs using simple Python code. Triton kernels can be both highly performant, as well as portable across different GPU architectures. For this reason, Triton is growing in popularity, and many LLM inference frameworks, e.g. VLLM (

https://github.com/vllm-project/vllm)

, already include several kernels written in Triton.

Despite the promise of Triton being adaptable to many different GPU platforms, to do so still requires manual performance fine-tuning in practice. In this context, we aim to answer the following research questions:

1. Can ML-based performance models of Triton kernels predict their performance on different hardware with sufficiently high-accuracy? Can these performance models then recommend the best adaptation strategies?
2. How can we adapt existing Triton kernels to new platforms like NVIDIA’s Tensor Memory Accelerator? Potentially using established compiler-based optimizations?
3. Can we build an autonomous pipeline for fine-tuning Triton kernels for heterogeneous hardware?
