Hey everyone, and welcome back to another episode of the PyTorch podcast! I'm your host, and it's March 23rd, 2026. Grab your favorite morning beverage because we've got some really exciting developments to dive into today.
You know what I love about today's activity? It's one of those days where the PyTorch team is firing on all cylinders - we're seeing performance improvements, infrastructure upgrades, and those delightful little optimizations that make everything just a bit snappier. No merged pull requests today, but we've got 23…
Let's start with the star of the show - Corbin Robeck just landed something pretty special. They've added a new non-TMA persistent matrix multiplication Triton template specifically for max-autotune. Now, if you're thinking "what does that mean for me?" - here's the beautiful part: this change is delivering around…
What makes this particularly elegant is that it brings persistent-kernel-style matrix multiplication to platforms that don't have TMA support. It's like the team looked at AMD GPU users and said, "Hey, you deserve that same performance boost too." The testing happened on an AMD 350 machine, and those performance…
Speaking of infrastructure…
