Bases 6-32 reservations/statuses/primes - Page 53

Sierp base 31 is at n=12K; 43 primes found for n=11.5K-12K; 89 primes found for n=11K-12K. 1733 k's remain. I'll report future statuses every n=1000.

We should be able to get this one down to < 900 k's remaining by n=25K. Even with the huge conjecture of k>6.3M, at that point, it should be easier than base 19.

It's what I would call right at the limit of being somewhat manageable, unlike other 2^q-1 bases such as 3, 7, 15, and 63.

Sierp base 31 is at n=13K; 94 primes found for n=12K-13K. 1639 k's remain.

Base 10 (Riesel + Sierpinski) doublechecked till n=240000.

Sierpinski base 12 is complete to n=300K, no primes. Results for 250K-300K are attached. Continuing to 400K.

Holy crap, that was fast on base 12! Thank you Rogue and PFGW and Max too!

Actually, that part of the range was done before the new PFGW was released; it was done mostly with Phrot, and partly with LLR. It helped that I had all of my quad running straight on it 24/7 until it was done.

(Well, with the exception of the time when your servers were down; during that whole time my quad was falling back to the PrimeGrid servers as backup.)

Meanwhile, I did a rough estimate on the 300K-400K range, again assuming my quad works on it straight until it's done, but this time with the new PFGW. My estimate came out to about 18-20 days or so.

It is, as I said, a rough estimate, though from the way things are looking I'm hopeful that it will go at least that quickly. Or, hey, maybe I'll find a prime and get it over with even sooner.

Ah, the full quad does it. I remember that to do n=200K-250K, it took me a couple of months but I only had one core on it running LLR for about the first half and Phrot for the second half after I discovered how much faster it was.

This is amazing news for the conjectures! Maybe we'll finally be able to prove some of these lower bases with 1-3 k's remaining.

Reserving Riesel Base 27 to 1M (last k 706)

Running this with PRPNET and PFGW

gd_barnes · 2009-08-05, 09:49

That should keep you entertained for a while if you don't find a prime at a lower limit. :-) Good luck!

MyDogBuster · 2009-08-05, 11:04

Reserving Sierp Base 24; all k's from n=35.3K to n=100K.

I try knocking some out of the 130 left.

gd_barnes · 2009-08-05, 11:20

Cool. You kind of like those PRPnet servers and the new PFGW, eh?
