This metric is simply no good.  What if a 1 cpu search hits 1M nodes per second,
and takes 2 minutes to complete 15 plies.  And the 2 cpu search hits 2M nodes
per second and takes 2.1 minutes to complete 15 plies.  Which one is better?

NPS is like a tachometer in a car.  Doesn't say a thing about how fast the car
is moving, just says how fast the motor is rotating.
