OK, I'll upload the 50G-208G files two weeks or so from today. However, the DC effort for 1-208G will start at 3P, since I've reserved 1-3000T for 50G-208G. This is because none of my computers have enough RAM for sieving 1-208G at once. I'll send the factors for 1-3P over once PrimeGrid reaches 49G, and cipher can finish 1-50G until 3P if he wants to.

MOOOMOO I would love to finish 1-50G to 3P but i might have to recruit Joshua2's or someone elses help or without any help it will take me 3+ months to achieve 3P on my own.

I think 3+ months is ok. I plan to continue on n=333333 for a few months or until a twin is found. Then if your still not done, I can help. I would prefer to just start sieving all k's at three p though.

n=500,000
range= 0-50G
sieving depth= 628.2
candidates= 17,930,281
Avg K per 1M = 359

n=500,000
range= 0-50G
sieving depth= 900T
candidates= 17,556,895
Avg K per 1M = 351

cipher · 2007-04-22, 23:26

n=500,000
range= 0-50G
sieving depth= 1000T
candidates= 17,449,512
Avg K per 1M = 349

Joshua2 · 2007-04-25, 05:08

It looks like your doing 100T per week. So in about twenty weeks, you will be up to 3000T. I would guess that is around how long n=333333 will last. Is that about right? Wouldn't it be only like a 25% chance to be done before twenty weeks? If we finish this n first, then I can help, and we could get it to 3P in just a few weeks.

Sounds about right. Joshua2.
Thanks

I can help but I don't know what to do. Please send me a PM with details.
Thanks.

We need the most help with n=333,333, as that n is still 10 times below the optimal sieve depth. I'm not too worried about n=500,000, since PG won't be working on that n until a year or two from today (assuming average luck).

If you still want to help out with 500,000, PM cipher for the 1-50G file. You can sieve the last part of the range (maybe 2500T-3000T?), while cipher can finish the first part.

edit: Check out http://www.elaurian.org/tpsieving/ if you need further help for sieving n=333,333.

n=500,000
range= 0-50G
sieving depth= 1100T
candidates= 17,353,736
Avg K per 1M = 347

p.s: PM me Carlos if you like to help out with n=500000 but we really need help with n=333333 (as moooomoo stated). Also let me know your system specs and if you have more than one machine include all your system specs of the machine you plan to run Sieve on. Thanks
