#FluidX3D #CFD v3.7 brings faster Q-criterion isosurface rendering with #OpenCL local memory optimization! 🖖🤠
https://github.com/ProjectPhysX/FluidX3D/releases/tag/v3.7Instead of 32 velocities for each #GPU thread, now an 8x8x8 workgroup loads & reuses 11x11x11 velocities in L1$, a 12x VRAM BW reduction.
Fascinating insight: Which thread loads which cell from VRAM to L1$, and which thread renders which grid cell within the workgroup, can be very different!

OpenCL 3.1 is here.
The Khronos Group has moved several capabilities into the core spec, including SPIR-V kernels, subgroups, and integer dot products.
Also includes improvements to the memory model and synchronization, plus better alignment with Vulkan via device UUID queries.
Implementations are already underway across major vendors and open source projects.

The OpenCL Working Group has published the first in a series of cooperative matrix extensions — and your feedback can help shape them before finalization.
cl_khr_cooperative_matrix brings cooperative matrix load, store, and multiply-add to OpenCL, developed with Arm, Intel, and Qualcomm. A companion OpenCL C language extension is also in RFC.

OpenCL, SYCL и матрицы
В данной статье я описываю свой опыт разработки приложений с OpenCL/SYCL. Вычисления на видеокартах ассоциируются преимущественно с графикой, научными вычислениями и с недавних пор с нейросетями. Но чаще всего с графикой. Тем не менее, графические процессоры обладают свойствами, за счёт которых их очень удобно использовать в задачах, напрямую не связанных с перечисленным выше. И главное из этих свойств – массовый параллелизм. Самый краткий ввод в гетерогенное программирование: у нас есть две роли — хост и девайс , задача хоста – формировать задачи и отдавать их на девайс, в то время как задача девайса обработать их и вернуть результат. При этом хост и девайс могут быть одним вычислительным устройством (это не обязательно CPU + GPU, так как CPU может отдавать задачи сам себе).

I just uploaded the 5000th #OpenCL hardware report to @sascha's gpuinfo.org database! 🖖🥳 And guess what #GPU I reserved the spot for: #Intel Arc B580 #Battlemage 🟦

I have contributed 4.2% (211) of all entries. 🖖🫡 -
What an honor to start the #IWOCL conference with my keynote talk! Nowhere else you get to talk to so many #OpenCL and #SYCL experts in one room! I shared some updates on my #FluidX3D #CFD solver, how I optimized it at the smallest level of a single grid cell, to scale it up on the largest #Intel #Xeon6 #HPC systems that provide more memory capacity than any #GPU server. 🖖😃

Hot Aisle's 8x AMD #MI300X server is the fastest computer I've ever tested in #FluidX3D #CFD, achieving a peak #LBM performance of 205 GLUPs/s, and a combined VRAM bandwidth of 23 TB/s. 🖖🤯
The #RTX 5090 looks like a toy in comparison.MI300X beats even Nvidia's GH200 94GB. This marks a very fascinating inflection point in #GPGPU: #CUDA is not the performance leader anymore. 🖖😛
You need a cross-vendor language like #OpenCL to leverage its power.FluidX3D on #GitHub: https://github.com/ProjectPhysX/FluidX3D

I'm getting the material ready for my upcoming #GPGPU course that starts on March. Even though I most probably won't get to it,I also checked my trivial #SYCL programs. Apparently the 2025.0 version of the #Intel #OneAPI #DPCPP runtime doesn't like any #OpenCL platform except Intel's own (I have two other platforms that support #SPIRV, so why aren't they showing up? From the documentation I can find online this should be sufficient, but apparently it's not …)

@BenjaminHCCarr another article on #GPU code portability where people put their heads in the sand and pretend very hard that #OpenCL doesn't exist...
OpenCL has solved #GPGPU cross-compatibility 16 years ago already and today is in better shape than ever. -
@dexter Here's the AMD w/ CUDA support/library/api/shim/translation/thing that came up the other day:
> ZLUDA is a drop-in replacement for CUDA on non-NVIDIA GPU. ZLUDA allows to run unmodified CUDA applications using non-NVIDIA GPUs with near-native performance.

讓 <del>Intel</del>AMD GPU 直接跑 CUDA 程式的 ZLUDA
先前提過「在 Intel 內顯上面直接跑 CUDA 程式的 ZLUDA」，結果後來事情大翻轉，AMD 跑去贊助專案，變成支援 AMD GPU 了：「AMD Quietly Funded A Drop-In CUDA Implementation Built On ROCm: It's Now Open-Source」，專案在 GitHub 的 vosen

[OUTDATED: PLEASE SEE https://eepy.moe/notes/9wty6rkb3j1r0b5d)
New account, new intro post
(yes this is pretty much copy/pasted with a couple of tweaks)
Hi! I'm Skye, who used to be @[email protected]
Some quick facts about me:
- I'm #transfem
- I have #autism
- My sona, also called Skye, is a transfem shark
- I live in the #UK (aka TERF Island :/ )
My hobbies:
- I do a lot of programming in languages such as #c++ , #rustlang , #kotlin and #pythonlang
- I know a decent amount about HPC programming (I've used #cuda , #opencl , #hiplang and #vulkan compute)
- I really love old computers, esp ones to do with the history of #HPC, such as #SGI machines - sadly I do not own any of these computers as of writing this :(
- I've participated in the homebrew scenes for the Original Xbox, and the PS3
- On the note of consoles, I own: an #xboxone S, a #PS3, an #originalxbox, a #Wii, and a #GameCube
- Other than programming aligned interests, I really like:
- #trains (expect me to post a lot of train photos/videos when I go on them lol)
- #cosplay - sadly I've never actually owned a cosplay or made one, however, I've been to quite a few comiccons around the UK, and one day, when I have the money, I'd love to make/buy a cosplay (I might make a cosplan post at somepoint?)
- I'm also into #mtb , and when I do it I may upload videos of cool shit I do lol
Shows I've watched and loved (and where my cosplans mostly come from lol - also, these are in no particular order):
- The Dragon Prince - #thedragonprince
- She-Ra (2018) - #shera
- Yakitori - #yakitori
- The Owl House - #theowlhouse
- Avatar: The Last Airbender - #atla
- The Legend of Korra - #tlok
- Arcane - #arcane
- Brand New Animal - #bna
- Voltron - #vld

Anyway, thanks for checking out my profile! -
I should mention that this isn't just a matter of the dominant player intentionally boycotting standards that would make them lose the vendor lock-in advantage (hello #NVIDIA). All major vendors are guilty of this one way or the other. For example, #AMD unjustifiably pulled (or maybe failed to add) #SPIR and #CPU support from their new #OpenCL implementation. #Intel's #oneAPI (even while still leveraging the OpenCL backend) effectively failed on any other OpenCL platform.
