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. Last fiddled with by jinydu on 2006-10-13 at 06:29

Because of Moore's Law, won't the CPU years/day increase enough in that time to lower the time significantly? I suggest approximately 1 and 3/4 years (August '08).

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.

So, I was wrong to say I was wrong, I was really right at first and the person that said I was wrong is really the one that's wrong, right?
Sounds like a tongue twister.

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.

 2006-11-16, 01:48 #10 jinydu     Dec 2003 Hopefully Near M48 2×3×293 Posts 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.
