    A hearty "Thank you!" to everyone who has contributed to this project.

    PrimeGrid SoB (Sieve) is stopping soon!

    Very soon! The exact date is not known, but the last tests will be made available 13 October 2010. As soon as those tests are done, the project will be suspended indefinitely. If you want to complete any badges, now is the time to do it.

    PrimeGrid SoB (Sieve) has stopped!

    The last wu was returned Nov 3, 2010. The project is now officially suspended. If new, more efficient, sieving programs become available, the project may restart. If the primality testing nears n=50M with k still remaining, the project will restart.

    sorry for necroposting ))

    am i right when saying that we can check lower bound at /secret/ page? it's around 22m now. with 200k increase daily it will be around 45M in 100 days.

    so basically we can restart sieving in 3-4 months?

    I think that number is highly suspect. There is no way we're increasing 200k daily. (If it were we would have gone from 0 to 22M in 110 days instead of 9 years.) Without some sort of breakthrough in computing speeds, or luck in knocking out a few k's, it will probably take many years to get to 45M. (my guess is even a decade is being way too optimistic)

    yes, i was confused with this number too

    first-pass 404110 22601782 49999997 10 +99955

    today number is half less, but still too high - 100k per day means 45M will be reached in 200 days. impossibru.
