Our "soft" goal of p=10P for PrimeGrid's one year anniversary contributing to the Prime Sierpinski Project sieve (13 October 2008) has been achieved. We reached it two weeks ahead of time. I call it a "soft" goal because it was only established a month ago as we realized the anniversary was approaching. :)

Congratulations to everyone on this AMAZING accomplishment. The past year has seen the doubling of seive depth and since this is a combined sieve file, both PSP and Seventeen or Bust have benefited greatly. PrimeGrid quickly became the top siever at both projects and now at SoB, represents 87% of the annual sieving and 39% of all time sieving, more than doubling the next closest contributor.

We'll go ahead and establish a firm goal for PrimeGrid's second anniversary. It's a very aggressive p=25P.

For more information, see About the Prime Sierpinski Problem. For Seventeen or Bust, please visit their site.

Thanks again to everyone for making all this possible.

15P, exactly how many PSP sieve WUs is that John?

Thanks for the info John. Nice to hear from you again my friend. Its been a while, but as soon as I finish my contributions to the CRUS project, I'll seriously consider help you reach your goal. Though according to the PrimeGrid Charts at www.primestats.net, the goal of 25P should be reached in 280 days if yesterdays rate of 34,635 WUs for PSP Sieve is maintained or even increases.

Well good luck on this goal, I'll if I feel like it and gets the ressources, contribute with my ~480 PSP sieve WU/day about a month from now. Anyone who has any idea if I need to find 997 factors to reach "factors found: 1000" how many Sieve WU do I need to crunch to reach that goal or is it even feasible at current sieve depth?

Hi John

About 11.1P. That means PG completed about 5P of work in one year. Next year's goal is to reach 25P which means we'll have to almost triple this past years production.

However, with continued growth and the recent sr2sieve speed up, we should be able to reach it easily. This may result in a mid year augmentation of the goal. We'll have to wait and see.

Great stuff. 1.1P in 2 weeks! That's 2.2P per month, which will put us at 26.4 + 11.1=37.5P at the second anniversary.

Although it's a moving target, is there any indication of the optimum depth?

With an n=50M as the top limit, we can sieve for a very long time. We've been cleared for up to p=100P. It all really depends on where and when we find primes.
