I’m late to the DGX Spark party but I finally got an NVIDIA Blackwell GB10 box!

Given $INTC is in the news, it's nice to see that the latest LM Studio and the OpenAI gpt-oss-20b model run at ~47 tok/s on an A770 using Vulkan.

Fun with Google Sheets AI: =AI("Should I buy this stock? Only answer yes or no."). Every symbol returns, "I can't provide financial advice" except for NVIDIA and ADOBE where the answer is "No." I love it!🤷‍♂️

The terse Section 3.1 of the DeepSeek V3 paper will be interesting to CUDA ninjas. Hide communications overhead while keeping the 8x GPU node busy: arxiv.org/pdf/2412.19437

How Did DeepSeek Train Its AI Model On A Lot Less – And Crippled – Hardware?

Maybe they should have called it DeepFake, or DeepState, or better still Deep Selloff. Or maybe the other obvious deep thing that the indigenous AI

My dad found this button from his time working on the Lunar Rover. Apollo 15 was the first to use the moon buggy. Good ink, it hasn’t faded very much!

You all said “Numerical Linear Algebra, L. Trefethen, and D. Bau. SIAM, (1997)” is invaluable so I got the paperback (PDF out there too).

I've been asked about this a lot, so let me provide a quick FAQ. Q: What's the nature of the issue? A: Anyone who has bought my book from Amazon in the past few month hasn't bought a genuine copy, but a lower-quality counterfeit copy printed by various fraudulent sellers.

Replying to @fchollet
For instance, if you go to the page of DLwP2 on Amazon, you see that it's being sold by a 3rd party seller named "Sacred Gamez". If you click "buy", you won't get the actual book from Manning. You get a low-quality counterfeit printed by the fraudulent seller (from the book PDF)

C-for-Metal: High Performance SIMD Programming on Intel GPUs

The SIMT execution model is commonly used for general GPU development. CUDA and OpenCL developers write scalar code that is implicitly parallelized by compiler and hardware. On Intel GPUs, however,…
