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.

Status report
 

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. :smile:

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

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. :smile: (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. :smile: 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. :wink:

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.

Base 27
 

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

Running this with PRPNET and PFGW

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

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

I try knocking some out of the 130 left.

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