A very fast GPU sort for sorting values within a wavefront
Buffer<uint> Input;
RWBuffer<uint> Output;
//returns the index that this value should be moved to to sort the array
uint CuteSort(uint value, uint laneIndex)
{
uint smallerValuesMask = 0;
uint equalValuesMask = ~0;
//don't need to test every bit if your value is constrained to a smaller range
