assume that we have enough global memory. Does replacing int with short improve the performance in CUDA? (like short saves the usage of shared memory, registers, etc)
Advices are welcomed. Thanks.
Using
shortin shared memory will most likely reduce performance due to bank-conflicts, until you useshort2.Also, as far as I know, all registers on GPU are 32-bit, so it’s unlikely that using
shortwould reduce register usage.
