Thread: Optimal Sieve Zone?

    Optimal Sieve Zone?

    As discussed in this thread at PrimeGrid: http://primegrid.com/forum_thread.php?id=2721

    PrimeGrid will be suspending SoB/PSP combined sieving, this means if people want to continue sieving then they will need to use the manual reservation system at http://www.sierpinskisieve.com - my question is, should we not also be considering suspending sieving and instead focus on PRP?

    Manual sieving is in the 71144200 -> 72000000 range, way below the PrimeGrid range with a higher density of factors.

    OK, we are going to take a break for a while. Manual reservations are now closed. When a more efficient sieve program becomes available, we will re-evaluate this decision.

    So we've reached the point where sieving efficiency is on-par with PRP testing? Does that mean that I should switch my PrimeGrid preferences to PRP testing instead of sieving?

    Yes, unless you want to get a badge before PrimeGrid sieving ends October 13, 2010.

    I already have the highest badge for sieving, so I reckon it's time to switch my computing preferences.

    13 October is approaching!

    This will be the last insertion date for PrimeGrid SoB/PSP (Sieve) before it is suspended. Until then, the queue will be kept full for anyone wishing to complete their last effort on this PrimeGrid sub-project.
