Thanks Lennart for the excellent boost on sieving! :)
A couple of notes for everyone here: First, depending on how quickly we progress on sieving here, I might suggest that we sieve it up to P=25T; IF that can be done by June 20th. Otherwise we'll stick with P=20T. P=25T is going to be slightly more efficient as for total sieving plus LLRing time up to n=600K but I don't want to delay the start of the new drive any more than the 20th. Second, Lennart has finished LLRing k=30003400 for n=20K50K. Previously Karsten had already LLR'd k=20003000 for n=20K40K (it's not in the sieve file right now) and he is in the process of LLRing n=40K50K. Therefore I am suggesting that Max remove the n=20K50K range from the sieve file and repost it on our noprimeleftbehind.net server. Once that is done, I'll post it here and you can choose whether to stop your sieve, replace your sieve file with the smaller one, and then restart it.

Funny! :) But aren't you using a full quad? If so, shouldn't it be P=125G vs. 250G per core? I just realized that both of us were likely wrong there; unless you're using only 2 cores. (lmao)

12000G / 6 * .3456 + 10955 75 = 691,210,880 or 0.691G A completely nonsensical answer so some of your figures must be incorrect. For instance, where did the .3456, 10955, and 75 figures come from? The 10955 and 75 have almost no effect on the total answer since they are so small and are additions or subtractions from something in the billions. I even tried them assuming they were billions and couldn't come close to what you came up with. Plug exactly what you put there into Excel or any calculator and you'll get what I came up with. Not that this matters a whip. Last fiddled with by gd_barnes on 20090602 at 01:23

Would also take a range. 12400G12650G, 125G per core. Hopefully I didnĀ“t make a mistak in the math. ;)
Edit says: Would be nice to have the link for the sievefile. ;) Last fiddled with by Svenie25 on 20090602 at 11:02

Lennart, do you still have the sieve file posted on your web page? If so, could you give Sven a link to it?
It will be a day or so before Max gets the file posted on the noprimeleftbehind.net server and has it set up so everyone has access to it. I tried it and it gave me a "permission denied" message. Once he gets that taken care of, he will have removed all n<50K from the file, which should speed sieving up by ~12%. (weepee!) :) Sven, if Lennart doesn't still have it on his web page, I'll Email the file to you later today. Gary
