Space Filling Curves

Pros

1. There is a marginal difference even though index of next position of the curve has to be calculated

Cons

1. Array has to be padded to a power of 2
2. Parallelism is slightly trickier as the offset of each thread has to calculated
3. It initially looks as if only static scheduling can be done
