Senior Principal Engineer, gaming and engines @ Intel. Opinions are my own.

@gregreisdorf I still have the source code for it! I'd do it again too. That handshake led me to my career at Intel and I still work in games 20+ years later.

[Jeff Rous @jeff_rous]

@iveytron A bit sparse and missing most of the big companies on the expo floor. It seemed like a shift towards indie titles has happened.

@artbyrens No trouble on Intel's end supporting 5.5. https://t.co/k61CfZdR5l

[ISPC @ispc_updates]

🚀 New ISPC v1.26.0 Release! 🚀
🔹 Improved ARM support & performance
🔹 New "generic" targets simplify ISPC design & ease new targets support
🔹 Better code generation for x86 & ARM
🔹 Lots of stability fixes

@34pixRed @ispc_updates Alive and well! Devs can use ISPC in their projects just like other source files. We add a bit more goodness every UE release.

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: https://t.co/CfvmPPH9YX #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.

Just released ISPC v1.21.0! Now with template function specialization support, optimized signed integer overflow rules aligned with C/C++, an enhanced ISPC Runtime, plus numerous stability and performance improvements. https://t.co/6hmLsNmvbR

[Jeff Rous @jeff_rous]

@halogenica Congrats Mike! Looking forward to working with you again!

@jon_c_kennedy @pbrubaker @tom_forsyth @omershapira 4090 moved more than you'd expect to CPU bound

[Jeff Rous @jeff_rous]

@pbrubaker @tom_forsyth @omershapira To those still sitting on the sidelines, why?

[Jeff Rous @jeff_rous]

@pbrubaker @tom_forsyth @omershapira ISPC code has been run by 500+ million players in Unreal at this point. It has proven its value alongside other industry standard tools such as Clang and MSVC.

[Tim Sweeney @TimSweeneyEpic]

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 Graphics @IntelGraphics]

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!

[Jeff Rous @jeff_rous]

@psjarlo The ISPC build step is done first to generate the headers C consumes. Then link the ispc and C obj files into the final binary.

[Jeff Rous @jeff_rous]

@psjarlo Unfortunately not. I started with bare bones C and asm kernel bits and went from there. This is a great resource. https://t.co/YgzqMq8g0C

[Arseny Kapoulkine 🇺🇦 @zeuxcg]

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 🤯

[Jeff Rous @jeff_rous]

@dsuoch I use this for my own tools. Or es as the other replier said for command line.
