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…

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…
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
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…

🚀 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…

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.

@realGeorgeHotz @ajmedick @TensorWaveCloud 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…

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…
Demystifying Debuggers, Part 3: Kernel Support For Debuggers On how kernels collect and expose information about program execution to debuggers.
Posted v8 of the uncached buffered IO patchset. This should be fine for merging at this point, let's hope we can make the 6.14 kernel release. lore.kernel.org/linux-fsdevel/… Separate branches exist for the core support and fs support, see the cover letter for details.
Posted v5 now, various fixes and cleanups. Should be good enough for folks to apply and test at this point, would love to hear how it works for folks. XFS and ext4 are fully supported for both uncached reads and writes. lore.kernel.org/lkml/202411101…

V3 below. Did a bunch of testing and fixed a few corner cases, should be solid now in terms of not over-caching. Writes run consistently at 180GB/sec uncached. And while I test on a big box, many practical uses for this on smaller iron. dd(1) needs this. git.kernel.dk/cgit/linux/log…

Uncached buffered IO is back, after a 5 year hiatus. Simpler and cleaner now. Up to 65-75% improvement, at half the CPU usage on my system. And none of the nonsense of the unpredictability of the page cache. See commit 1 and 3 for read/write perf data. git.kernel.dk/cgit/linux/log…
meshoptimizer 0.22 is out! Featuring significant improvements to simplifier (attribute simplification, fewer topology restrictions, component pruning), new provoking vertex algorithm (thanks to John Hable), clusterization improvements & gltfpack size optimizations. Thanks to…
Just like I did for 6.10, I wrote up a "what's new with io_uring" but for the 6.11/12 kernels. 6.11 wasn't super exciting in terms of features, so bundled these into a single page. github.com/axboe/liburing…
