> Plane (warp in CUDA, subgroup in Vulkan/Wgpu): a group of (typically 32) units executing in lockstep and able to share data efficiently through registers.

It's already bad enough that the vendors themselves insisted on different names but why in the bejesus would you rename these concepts and diverge from literally all existing naming conventions when you're providing middleware. Ie when using your tool I'm still going to reference NVIDIA's or AMD's docs to understand how the hardware actually works. Like do you really think otherwise - that your thing is gonna be end of the line???
FYI the word warp isn't random techno babble but is actually a very clever pun that actually fits very well conceptually:
