If you test the 300k1M sieve speed vs 200k1M, you'll find that there's very little speed gain, meaning the 200300 piece is, in a sense, getting sieved for free since we'll want the rest of the file sieved more. The heuristic I've found is that sieving until the sec/factor is at least double the LLR time for the smallest candidate is at the lower end of the right time to break off a piece. However, you won't be LLRing it yourself BOINC will. Just like the NFS@home matrixsolvers have NFS@ home make extra relations to make their matrix task shorter, there's nothing wrong with sieving less for BOINC than you might for yourself. For Riesel3, I've been sending pieces of the sieve files to rebirther when sec/factor in sieve is the same as sec/test in LLR for a typical candidate in the piece. 30e12 would be a good spot to aim for for BOINC work, 5075e12 for your own work.

Thanks for the reply, I found that, or something similar. I got the idea that I need to sieve to 3e13, that is what I need to know. In a sense, as you said, if some prime divides some s(n), the n is "random", so its chance to be in 300k1M is 7/8 from the chance that n is in 200k1M, and this is what the factor list shows: about one in 8 is in 200k300k, and i get one every ~125 seconds, i.e. about 1000 seconds per factor.

Do you also need some XXL tests? I could give you a readytogo sieve file for S/R22 n=1.5M  2M.

R347
Here's the sieved file (P=20e12) for R347 from n=200k400k. There are 1679 candidates remaining.
Edit: I can go ahead and run base 373 as well. Nevermind, got it sorted. Last fiddled with by wombatman on 20151215 at 20:21

S428 status report: reached 12T, continuing to 30T as per Curtis' advice. In the same time I let cllr running for S428(8), it reached n=120k (this is a DC, but I don't think I will go to the full n=200k, as it is already getting very slow).

S/R373 and R610
R/S373 (k=18 and k=108, respectively) is on its way to P=20e12 and should finish Christmas Day.
R610 is heading to P=15e12, finishing on the 23rd.

Later tonight, I'll include a list of what is being worked on and who has what reserved for BOINC sieving in the first posting here. I'll also put a link to all completed files on the pages. Ian just sent me a large batch of bases sieved for n=25K100K. That should keep BOINC busy for a while. :)

I received a large batch of sieve files from Ian for n=25K100K and 100K=200K. There is now a link to all of them on the pages. They are as follows:
