Using CUTLASS CuTe-DSL, TogetherAI's Chief Scientist @tri_dao announced that he has written kernels that is 50% faster than NVIDIA's latest cuBLAS 13.0 library for small K reduction dim shapes on Blackwell during today's hotchip conference. His kernels beats cuBLAS by using 2…

Cute-DSL is basically perfect (for me). thank you nvidia and cutlass team. i no longer need to wait for long compile times because i underspecified a template param. i hope everyone involved gets an extra chicken nugget in their happy meal

On Sep 6 in NYC, this won't be your typical hackathon where you do your own thing in a corner and then present at the of the day. You'll deploy real models to the market, trades will happen, chaos should be expected. The fastest model is great but time to market matters more.

Part 2: developer.nvidia.com/blog/cutlass-3… Covers the design of CUTLASS 3.x itself and how it builds a 2 layer GPU microkernel abstraction using CuTe as the foundation.

Hierarchical layout is super elegant. Feels like the right abstraction for high performance GPU kernels. FlashAttention 2 actually started bc we wanted to rewrite FA1 in CuTe

CuTe is such an elegant library that we stopped working on our own system and wholeheartedly adopted CUTLASS for vLLM in the beginning of 2024. I can happily report that was a very wise investment! Vijay and co should be so proud of the many strong OSS projects built on top 🥳

Cosmos-Predict2 meets NATTEN. We just released variants of Cosmos-Predict2 where we replace most self attentions with neighborhood attention, bringing up to 2.6X end-to-end speedup, with minimal effect on quality! github.com/nvidia-cosmos/… (1/5)

Getting mem-bound kernels to speed-of-light isn't a dark art, it's just about getting the a couple of details right. We wrote a tutorial on how to do this, with code you can directly use. Thanks to the new CuTe-DSL, we can hit speed-of-light without a single line of CUDA C++.

🦆🚀QuACK🦆🚀: new SOL mem-bound kernel library without a single line of CUDA C++ all straight in Python thanks to CuTe-DSL. On H100 with 3TB/s, it performs 33%-50% faster than highly optimized libraries like PyTorch's torch.compile and Liger. 🤯 With @tedzadouri and @tri_dao

We've been thinking about what the "ideal" architecture should look like in the era where inference is driving AI progress. GTA & GLA are steps in this direction: attention variants tailored for inference: high arithmetic intensity (make GPUs go brr even during decoding), easy to…
