Hm, as always exact cycle counts would have helped a lot, but anyway... The problem of your kernel is, that some of the writes (PF1/2) for the right half of the PF come too early. Here are the timings (directly copied from my Thrust kernel): Left: PF0: z <= 22 PF1: z <= 27 PF2: z <= 38 Right: PF0: 28 <= z <= 49 PF1: 38 <= z <= 54 PF2: 49 <= z <= 65 I'm not sure if the cycles are 100% exact (IIRC right PF2 can start from 48), but they should give you an idea. > Any insights or common knowledge and sarcasm would be appreciated. No > public berating could be too harsh.. ;) I hope that's what you've asked for. ;-) Have?fun!
