'Are there performance/storage differences between uint2 and uint64_t in cuda10+?
I'm trying to optimize a piece of code for A100 GPUs (ampere gen), right now we use uint64_t but I am seeing uint2 datatypes being used instead in some cuda code. Does the uint2 offer advantages for register usage? I know there are a limited number of 64-bit registers, does uint2 split the x,y ints across 32-bit registers for better occupancy? I couldn't find any specific information about register storage with these datatypes so any links to documentation for it would be appreciated.
