Answer 2

As far as i know - The whole "mapping" means finding correlation ( e.g statistical correlation) between the genome and known physical phenomena like some disease or "color of the eyes". That requires a lot of number crunching.

Answer 3

Genome annotation. It is much faster and less error prone to do this in a computer rather than by hand, and a supercomputer does it faster than a normal computer.
