Intel Open Image Denoise 2.1 is out! It adds support for denoising 1- and 2-channel images, enables mixing data types for input features, improves performance on most discrete GPUs, and fixes several issues: github.com/OpenImageDenoise/… #IamIntel

The Intel Software Developer Manual needs to be better organized, more consistent, and have erroneous descriptions fixed. Here is an attempt at revising the instruction listing with refined descriptions logically grouped instead of in alphabetical order.

Intel's new Raptor Lake architecture (powering the 6GHz Core i9-13900KS and others) is insanely fast. Not just a record clock rate, but I'm also seeing an IPC improvement around 15% over Intel's previous generation in the code I'm running. Wow.

Intel is incredibly excited and honored to partner with Epic Games as a sponsor of MegaGrants. We can’t wait to see what developers create with the power of Lumen, Nanite, and #RayTracing on #IntelArc Graphics!
Four years in and the Epic MegaGrants program is still going strong!
See some of the most impressive 2022 MegaGrants projects and hear about the new Epic MegaGrants Perks Program inside.

Benchmarking tips: make yourself a power plan that clamps CPU freq to min/max 99%; this disables turbo boost and generally speaking locks the frequency at base-ish, which helps get more stable measurements (works on desktops!).
I've only learned this this year from @rygorous 🤯
So glad you find it useful! It started with Chaos physics and expanded from there (animation, audio, Niagara, rendering). Every release we add a bit more. Seeing those 4x gains never gets old!

Hey ISPC Twitter! We could use your help! 🙏
We would like to get a better understanding of who is using ISPC and where.
Are you using it at your company/uni or on personal projects?
Do you have feedback (pro and con) about the compiler?
Reply here, or DM us privately! 1/2

I open-sourced my book about SW performance. All the source Markdown, images, and Latex files are now open. Anyone can easily build a PDF version.
This book now belongs to the whole community. I invite everyone to contribute to it.
