Compute shader thing: I'd love a way to declare that "these two shared arrays have non-overlapping lifetimes and can share storage".
@rygorous Like maybe the compiler did something stupid, and there's no way for me to help it, or I just can't figure out how to tell it.

@rygorous But that's purely conjecture, since I have no way of knowing what it's actually executing... -
@rygorous ... so I was hoping either "nsight" or CUDA would give me some way of getting either a reference or a better way to inspect. - Show replies

@cmuratori CS perf takes a very steep nosedive once the number of warps/wavefronts on a single compute unit goes below a certain number. -
@cmuratori Which happens when you have too many live regs, use too much shared mem, or have too few instances running. - Show replies
