I am not a petaflop

I always figured that a petaflop was the manoeuvre I made when settling in to a nice long nap. Turns out that it is a milestone in computing performance, not at all related to my having a snooze. The next thousandfold goal is the exaflop, which is a quintillion calculations per second, followed by the zettaflop, the yottaflop and the xeraflop.
