If you want to optimize for speed on large parallel systems, starting  
from a fast sequential algorithm is usually the worst approach you can  
take. Optimizing for parallelism requires a completely different way  
of thinking, and indeed often includes approaches that would seem  
wasteful in a purely sequential environment.
