Not necessarily. The C code runs on the front end processors, which are usually Intel Xeons or something like that. Then one shoves specialised routines into the NVIDIA cores. I've no idea whether it is there or not. But one would think that given that these things came from graphics, XORing should be there. The problem is, even if it is there, it isn't part of any FP standard, so it is not guaranteed to be supported on other such devices.
Anyhow, I'll look up the CUDA "standard" and see.
