As far as the useful-but-not-terribly-long thing goes, Double Check LLs are around 28M at the moment, which means that while a 48M expo is something like 90 GHzDays to test, the 28M double check would take ~25 GHzDays to do, which would only be around 2 months on the laptop (and we could always use more DC throughput). Just food for thought.

scubabob,

None of your clocks are wasted, as long as you're cooperating with PrimeNet about assignments. Some folks confuse the worktype on which a particular CPU has maximum efficiency with the only worktype worth doing by that CPU. But like LaurV, I'd encourage you to continue doing what you like best.

P.S. I was an assembly programmer, too, for many years and also had a fondness for maximizing what those wonderful CPUs could did.
