Demystifying Debuggers, Part 3: Kernel Support For Debuggers On how kernels collect and expose information about program execution to debuggers.

So what have I been up to this year? Hardware raytracing, Vulkan, deformable voxels, engine architecture, physics and lots of multithreading. blog.voxagon.se/2024/12/29/yea…

We've got another exciting technical report to share with you today: 🎓 A Numerically Stable Implementation of the von Mises–Fisher Distribution on S^2 Read the full report via GPUOpen (direct link - 1MB PDF): gpuopen.com/download/publi…

George Hotz 🌑 Alex Medick I've been running AMD GPUs for many years now. 150k of them, so not some small operation. Even though every single GPU was a snowflake, the hardware was generally fantastic. 20k of those were the PS5 APU chips, which I got to know very well. We automated tuning the living

The core of this work is now upstream in Linus's tree, and the per-fs bits have been rebased on top of that: git.kernel.dk/cgit/linux/log… xfs/btrfs/nfs should be fine to include, ext4 would ideally need an iomap conversion first.

🚀 Day 2 of #OpenSourceWeek: DeepEP Excited to introduce DeepEP - the first open-source EP communication library for MoE model training and inference. ✅ Efficient and optimized all-to-all communication ✅ Both intranode and internode support with NVLink and RDMA ✅

🚀 Day 3 of #OpenSourceWeek: DeepGEMM Introducing DeepGEMM - an FP8 GEMM library that supports both dense and MoE GEMMs, powering V3/R1 training and inference. ⚡ Up to 1350+ FP8 TFLOPS on Hopper GPUs ✅ No heavy dependency, as clean as a tutorial ✅ Fully Just-In-Time compiled

I thought I'd share this, it might be useful to some... I have a small collection of stb-style single-file header-only C libraries, most with a dual MIT/public domain license here: github.com/mattiasgustavs…

Among other features, RDNA 4 introduces "out-of-order" memory accesses to AMD's GPU line. Time to test it, and see if the same applies to other GPUs chipsandcheese.com/p/rdna-4s-out-… old.chipsandcheese.com/2025/03/23/rdn…

RenderDoc v1.38 is now available! This version contains a number of new bugfixes and some usability improvements. Full release notes: github.com/baldurk/render… Binary builds: renderdoc.org/builds

Radix Sort is a fast, non-comparison-based algorithm ideal for sorting large datasets especially on GPUs. 💡 Check out our research that introduces a memory-efficient GPU Radix Sort that improves on Onesweep: gpuopen.com/learn/boosting…

PyTorch + ROCm on Windows: community powered. Thanks to the great work by Aaryaman "Jam" Vasishta and Scott Tsai on the port and TheRock team building a community first build and CI system for ROCm

Hello you fine Internet folks, Today's article is on Nvidia's RTX PRO 6000 Blackwell and diving into the Blackwell architecture generally and more specifically into the GB202 GPU die in the RTX PRO 6000. Hope y'all enjoy! chipsandcheese.com/p/blackwell-nv… old.chipsandcheese.com/2025/06/28/bla…

AMD Officially Confirms The End Of The AMD Radeon AMDVLK Driver phoronix.com/news/AMDVLK-Di…

indico.freedesktop.org/event/6/contri… - Looks like I missed this gem from 2024, yeah definitely bring RADV to Windows, I would love to be off the AMD drivers and instead contributing optimization bug reports to RADV.
