#FluidX3D #CFD v3.7 brings faster Q-criterion isosurface rendering with #OpenCL local memory optimization! 🖖🤠
https://github.com/ProjectPhysX/FluidX3D/releases/tag/v3.7

Instead 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!

PS: plugged X-wing Gif in #GitHub preview 🖖😜

Heh, I found (and reported) a bug in one of #Nvidia​'s oldest and probably most thoroughly tested libraries: NVML memory clocks are wrongly reported in (MT/s / 2) instead of MHz, which means they are wrong for all #GPU​s with GDDR5-7 memory types. Really no code can be trusted. 🖖🫠

#OpenCL 3.1 is here!! 🖖🥳🎉

Let's try something: You can plug an animated GIF into the #GitHub social preview image. Good eye-catcher in the GitHub topics listing and when sharing repos.

Also: Already 2 updates for hw-smi! Better #Intel Arc Alchemist & iGPU support, and more robust compiling across #Linux distros. Users testing on lots of systems and sending me feedback is win-win!

#FluidX3D #CFD has reached ⭐ 5000 Stargazers on #GitHub! 🖖🥳
Grid refinement update is still in development, I haven't forgotten... ⬜◻️◽▫️

Newest #IntelArc #GPU family member is here, the Panther Lake Arc B390... and it... purrs? 🖖 🥺 🐈‍⬛
My OpenCL-Benchmark on the B390 measures ~7.4 TFlops FP32 and ~120GB/s memory bandwidth. hw-smi also works with the B390.
