Reserving sierp b19. Will try my luck, to eliminate some of those k :smile:
Should keep my systems busy for a few months..
Is there any sieve file, I can continue?

Well Gary should have a sieve file going to n=100K, for all k's remaining at around n=5K, however you should be able to find at least 4 or 5 k's for each 1K n's, for at least the first few thousands n's. Previously predictions (if I recon properbly) is that there should remain ~987 k's at n=100K :smile:

KEP!

Ps. Further sieving may be needed to reach optimal sievedepth...

Riesel Base 15

I believe this leaves 15 k's

Reserving Riesel base 23 from 200k.

Sierp base 26 is now complete to n=200K. No primes found for n=100K-200K. I'll keep it reserved to n=250K but am switching over to the Sierp base 23 PRPnet drive for n=200K-250K right now. After that, I'll be working on the final k for Riesel base 22 for n=220K-300K along about the time that Tim is ready to do the same for n=200K-220K. After that (likely about a month) I'll get back to Sierp base 26 for n=200K-250K.

I seem to be jinxed on big primes right now.

I corrected k=21776 to 21774. To make it official: 93 k's remain on Sierp base 24 at n=100K.

Did you know that you missed a top 5000 prime on this base by a mere ~1000 digits? That's right 4799*24^99451+1 is 137268 digits. The current 5000th prime is 138610 digits. As fast as it is rising, you actually may have had one for a couple of days when you posted this.. lol :smile:

Thanks for the huge amount of work done. 130 k's to n=100K is nothing to shake a stick at. I found it interesting that you knocked out the 2 lowest and 2 highest k's remaining.

A note to everyone for bases <= 32. If you are testing at n>~90K and find a prime, be sure and check its size for top 5000 reporting.

Reserving Sierp. base 28 from 150K-200K.

Reserving R-base 31 from 100k to ?
All 8 ks.

(This will keep primes in the top-5000.)

[quote=Mini-Geek;191550]Reserving Riesel base 22 n=200K to 220K. (this is the one with just one k left, should take about a week from when I start) Will begin once I finish my FoB reservation (about Oct 16), assuming the sieve to 7T is complete.[/quote]

Tim,

I just thought I'd verify that you've started on n=200K-220K. After Max gets back on Thursday, I'm going to have him load up a personal PRPnet server with n=220K-300K and put a quad on it until it's done. If I'm lucky enough to find a prime before you're done with your range, I'll wait to report it until you're done since the lowest prime should be the one to prove the conjecture and would be what is reflected on the web pages. (I'll then report mine later.) If you find one first, I'll just stop processing my range.

As a SWAG estimate for the range on a quad, I'd guess 1.5-2 weeks.

Good luck! That will be a large amount of work, even if you only take it to n=150K. Base 31 k's tend to be heavier weight than most bases; hence have the best chance of finding a prime.

Yes. r-base 31 is [I]very [/I]heavy. I won't be taking it anywhere near 150k. Just enough to lift it a bit and leave a sieve file to encourage someone else to take the baton.

I've also started sieving r-base 30. I might test it a bit or just leave the sieve file for someone else to have a go.

Both of these will be under-sieved.
I need more cores!
