100,000 P1. 1,000,000 GHz Days saved
 
Not me....G72.

1,000,000 GHz-Days of LL tests alone is a LOT. That's almost twice as much as gets done in an entire year. About four times Curtisc's yearly throughput.

Go team GPU!

Actually, four times curtisc's yearly throughput would be [B]10[/B],000,000 GHz-days. But what's an order of magnitude amongst friends? :smile:

One million GHz-days, or 1 Petahertz-day, or just under 2740 GHz-years, however, is certainly still an accomplishment of which to be quite proud. Huzzah!

On 2013-01-22, I went through and added up all of the GHz-days totals in the account rankings for the last year, and then over every year back to 1996. I was quite shocked to find that some 28.5% of GIMPS all-time throughput had been achieved in the most recent 12 months! (For the number crunchers among us, I calculated 58,509,783 GHz-days since the Dawn-of-GIMPS(TM), and 16,678,308 GHz-days in the period 2012-01-22 to 2013-01-22.)

1 GHz-day = 5.075 P-90 years (original GIMPS work measurement). Assuming a single stock GTX 580 processes [url=http://www.mersenne.ca/mfaktc.php]433.2 GHz-days/day[/url] (running mfaktc), that single GPU will do what took George's original Pentium 90 an entire [i]year[/i] of work... every 17 minutes.

How things change; how they stay the same.

Are you sure you have this right? Check your calculation again.

Commander...

What, please, exactly, is your point?

TheMawn 2013-09-18 04:20

Whoops I saw 250k GHz-Days, not 2.5M. Haha. D'oh well. Still a great accomplishment.
