I feel like the most difficult part of subgroups and GPU programming in general, is getting all the terminology straight in your head. Sometimes it seems like it would be easier just writing rdna asm directly. :')
@dotstdy It's my favorite too. It used to be fashionable to deride it as marketing wank but I think it's evocative and memorable and the hierarchy of the terms makes sense once you know that warp isn't a sci-fi word.
@pervognsen Right I was about half way through typing that we could probably lose the CUDA cores :') People working on CPU marketing must be livid that GPUs get away with that after the whole "real cores" kerfuffle with bulldozer.
