Aye, Captain !

Does this imply what it appears to imply?

Presumably all of these CPU cycles are limited in performance by the
capability of the machines to process Double Precision Floating Point
Numbers?  :-)

Do you require afterburners to achieve the "supersonic" transition? ;-)
Or, have you kept the Reynolds Number low?
