Hm, not happy with SPIR-V to ISA on my RDNA3 that is reordering loads from shared memory in some ways that it is actually slightly less efficient...
Is there a way to instruct the ISA compiler via GLSL to not reorder loads from shared mem? (Not workgroup/subgroup barriers but simple no-reordering) I haven't yet tried if volatile could do the trick 
Anyone has some thoughts?

I let the simulation run for several minutes before recording. The edges do appear to be a bit sticky causing the flocks have a bias to moving parallel to them, but particles are only briefly trapped there before being pulled away.

The particles try to move in 3-D, but then their position is constrained so that z = abs(x).
Still seems to work with this particular set of forces, though it's not all that easy to see in this low-res, short animation.

Sorry for the not-so-high quality, I'm too lazy to export it to a direct video at the moment.

Over the past two months I've been actively revisiting, updating/extending and now close to finishing this 1.5 year long journey... The actual journey has been much longer, been toying with (faux) fluid sims since ~2007...
A 50 second preview of one of my fave variations, best enjoyed fullscreen... Tried to achieve some molten, dichroic/irridescent glass & oilfilm aesthetics here, but there're over a dozen of other very different routes/styles possible too, with 25+ parameters to tweak the simulation and look & feel...
