Greetings,
This appears to be a glitch in the program. The "CPU years" cannot be
greater than the "CPU yr/day". I have noticed from time to time in recent
weeks that the counter for "CPU years" does not roll back to zero at 06h
every day, which I think it is supposed to do, thereby allowing it to
accumulate more than 24 hours worth of work. The "CPU yr/day" formula
seems to take this into account, however.
I have been in the search for more than two years now, way before Primenet
came along. I'm sure everyone that has been on this ride for long enough
to remember being able to LL-test exponents below 2,000,000 for the first
time will agree that 35 to 40 years of work in a single day was never
expected, only dreamed about. Whoda thought we be testing in the 6,000,000
range by now?!?
How about some predictions on when the whole range up to 20,500,000 will
be:
1) completely factored to the available limit of the program?
2) completely first time LL-tested?
3) completely double-checked?
With the GIMPS status page showing about 535 millennium of P90 work to go,
considering present production, factors yet to be found and more and faster
computers coming online to help, I predict that all of the above will be
accomplished in under 10 years. Any comments?
Regards,
Gary Untermeyer
