As you can see, Curtis Cooper has now contributed over 100,000 CPU years to GIMPS, or over [tex]10^{20}[/tex] basic operations! Whoa!

Curtis Cooper now has over 100,000 P90 CPU years in LL testing alone! I think this is the first hourly report that shows this.

The shorter character string caused by the lack of the decimal point makes it look exclusive.

He has now contributed over 100,413 CPU years in total.

Since the first post in this thread, Curtis Cooper has added another 4425 total CPU years.

It took 1 month, 5 days and 12 hours to do this. At this rate, Curtis Cooper will reach 200,000 total CPU years on Jan. 11, 2009.

Since the previous post, Curtis Cooper has added another 4000 CPU years in LL testing.

It took 1 month, 1 day and 22 hours to do this. At this rate, Curtis Cooper will reach 200,000 LL CPU years on Jan. 12, 2009.

-------------------------------------------------------------------

By comparison, the userid curtisc was created in 1998 (unfortunately, I don't when in 1998). So it took about 8 years to do the first 100,000 CPU years. At the current rate, it will take less than 2 and 1/4 years to do the second 100,000 CPU years.

I suggest approximately 1 and 3/4 years (August '08).

Hahaha, Moore's Law doesn't hold for existing computers. It refers to the best CPU available.
It would only work for Curtis & Cooper if all their PCs would be replaced every few months with the best possible PCs!

Willem.[/quote]Moore's Law was the wrong term. I know that they aren't replacing their computers, what I'm saying is that as more computers join, they're going to be faster than current computers, and therefore the CPU years/day will increase enough to make the 2 and 1/4 year prediction wrong.

Moore's Law was the correct term. Universities upgrade their computers on a regular basis. Thus the total campus computing power does obey Moore's Law.

Sounds like a tongue twister. :rolleyes:

Jinydu

From the stats you've given the account would appear to have been created on or around 3 July 1998.

Dividing the total output (in p90 hours) by the average hours/day gives 3056 days. 3056 days before today was 3 July 1998.

Thanks for all the replies; I dreaded that this might become yet another thread where I was the only one who posted.

I think that the P90 CPU years/day figure includes both LL testing and factoring credit (someone please confirm or refute this).

Assuming that this is the case, the account curtisc seems to have been created on July 5, 1998 at 5 pm my time (US Pacific). So it took about 8 years, 3 months, 3 days and 16 hours to reach 100,000 total P90 CPU years and 8 years, 3 months, 7 days and 6 hours to reach 100,000 LL P90 CPU years.

If the P90 CPU Years/day figure includes only LL testing, the estimated starting date is July 18, 1998 at 5 am my time.

Also, I'm quite confident that my post pointing out when curtisc reached 100,000 LL CPU years gives exactly the right hour; but my post for 100,000 total CPU years is probably late by a few hours.
