[QUOTE=gd_barnes;135910]OK, I'll mark you down for it. Be sure and get the sieved file off of the reservations page.

Gary[/QUOTE]

Already grabbed.

All base 30s are done to n=100,000. I am releasing them.

For k=2038.Sierb. base 9. 230k-240k No prime.

I'm reserving all 4 k's for Sierpinski base 22, untill 1 million or primed.

KEP!

Have also begun sieving the remaining 6 k's total for Riesel Base 22 and 23 plus Sierpinski Base 23. So is also taking these. They will all be taken to 1 million n or primed.

Does anyone know, is it possible to use sr2sieve to sieve different bases? and is it possible to use sr2sieve to sieve both Riesels and Sierpinskis?

[/quote]

I think sr2 already does that, and yes, it sieves both Riesel and Sierp...if not you have to go to sr5 sieve source and change the sr5sieve.h definition of BASE.

Riesel base 7
 

Hi everyone,

as a side project I've tried the first million of the base 7 Riesel Conjecture.
There are 120 k's with with no prime below 2000
There are 14 k's with no prime below 35000:
48584
184434
257318
315768
328226
347004
477458
493032
512222
623264
747176
839022
913284
949992

Here is the top ten of primes so far:
k n
401994 32471
706712 32437
874026 30253
571388 26879
434556 26167
478826 21805
78648 19918
258582 18801
940146 17631
437754 15967

I have a sieve file that is sieved until n=100,000. I'll finish that and after that I'll leave this base for people with quantum computers.

Having fun, Willem

Yes, it should work fine with multiple bases in one sieve--and I know for a fact that it works with Riesel and Sierp. mixed together (the SR5 project does this). :smile:

Is that so??? I didn't know that. How can it be very efficient sieving multiple bases in one sieve?

I knew that it could do Riesel and Sierp in the same sieve but not different bases.

Assuming that it can do multiple bases for one sieve, I would test it first before doing so. It might take less total CPU time to run 2 instances of the 2 different bases than to run both bases in one instance.

Willem,

Before getting too far into any more side efforts, can you give an update on your Riesel base 19 effort? It looks like you were about done with that. You stated that you were going to n=30K with it and were already at n=25K with 1601 k's remaining.



Thanks,
Gary

Willem,

For historical reference, I have to get all of the primes found, both small and large, at some point from you. Do you happen to have all of them available for Riesel base 7 to k=1M?

I know you don't like to keep the small primes or results. If you don't have them here, how about I run PFGW on a couple of cores for a day or so up to n=5K to get the small primes and you can send me all of your primes for n>5K? I'm assuming you have all of those available.

I will shortly reflect your Riesel base 7 effort on the web pages. Next I'll be digging into your base 25 effort(s) to see if anything is needed there.


Thanks,
Gary

[quote=Siemelink;135451]Haliho everyone,

Here is an update on my Riesel 25 effort: at n = 15000, I have 337 k's left. 69 of those are also open for Riesel 5.

Willem.[/quote]


Willem,

I'm analyzing and balancing k's remaining on Riesel base 25 now. You apparently eliminated 20 k's between n=10K and 15K but I don't see any primes listed for them in any of your attachments here.

You dropped from 357 k's remaining to 337 k's remaining, which both included the 69 base 5 k's that are being worked on by that project. I just need the primes for that difference of 20.

Also, do you happen to have the primes for n<2K? If not, I'll run PFGW for a little while to get them.


Thanks,
Gary
