Thanks for the offer. I'm not stopping the BOINC effort from doing what it wants but I'd prefer that it not take on such a large effort for a base with no chance of proof in our lifetimes. After some of the smallish bases < 50 with large #'s of k's remaining have been searched to n=100K, I feel that the huge resources needed to search them higher would be better utilized in some of our high-n searches on bases with few k's remaining that have a reasonable chance of being proven. If you'd like to help sieve, consider taking our Sierp base 6 n=1M-2M file (12 k's). A link is on our reservations page. It is already sieved to P=220T. That would be the kind of effort I'd like to see BOINC go after.

Gary-
I prefer to help on Riesel bases. Does R30 fit your criteria? 9 k's, at 500k now, unreserved. If I built a sieve file for 500k-1M, would BOINC test it?

How long is the runtime?

Close but how about R28 instead? 4 k's for n=500k-1M. It's currently tested to n=450k by Ian and he should be done to n=500k anytime now. Another good one would be R37. 16 k's for n=100k-250k. I tend to look at the bases with lower relative difficulty (to catch them up so to speak) as shown at http://www.noprimeleftbehind.net/cru...s-unproven.htm.

Of course not stopping anyone from doing whatever he wants to do.

Should be done in about 2 weeks.

OK. R37 is a smaller sieve project anyway, in case I lose interest before a 500k-1M sieve is done. I'll start this in a few days, 100-250k.

For BOINC ranges between 25-200k are good at the moment. If someone want to sieve some bases in the list 10-25k or 100-200k with some smaller k this would be fine. So we can combine the power by sieving, starting new bases up to 10-25k and BOINC is testing 25-200k. At the moment the rate of 4.6k tests in progress are low. My goal is 10k. Iam always open for some wishes what bases are run first.

Are you suggesting I sieve 100-200k rather than 100-250? In the long run, this is fine, as the next sieve can be 200-500k to hit the usual next milestone. Note that base 37 is pretty low, so the tests will run quite a bit faster than bases over 100- meaning 250k isn't unreasonable.

For the smaller bases you can sieve up to 500k.

Attached is the sieve file, with just under 42000 candidates, for base R37 from 100k to 250k. Once you finish this file, I'll sieve the remaining k's to 500k.

I sieved to 5T. This produced a time per factor of just over 400 sec, with an LLR test of the first candidate taking 125 sec on the same machine.
