Cuda atomic operations on unsigned short

Are there some inbuilt functions in cuda for doing atomic operations on unsigned short or unsigned char?

Solution

  • No, there are no CUDA atomic intrinsics for unsigned short and unsigned char data types, or any data type smaller than 32 bits.

    However, you could group together two shorts or four chars and perform a 32-bit atomic on them, processing multiple at once (assuming your computation permits this).
