Find XOR of all numbers in a given range
...bits cycle every 4. So, that's how to arrive at that little lookup table.

What is a bank conflict? (Doing Cuda/OpenCL programming)
... Sweet thanks for the visual and the explanation. I didn't know about broadcasts and that seems like an important bit of information :) How would I go about verifying that my loads and stores don't cause bank conflicts in shared memory? Do I have to get at the assembly code somehow ...
