Riesel base 7
 

Ah, that reminds me, I found some primes too:
347004*7^98164-1
949992*7^96234-1

That leaves 5 remaining k's for this base, even though these are not all k. I've sieved deeper and I'll take these to 200,000

Ciao, Willem.

Willem,

Nice finds!

Are you now up to n=100K on all k's for this base?


Gary

[quote=japelprime;145079]base 9 Sierpinski. k=2036. I am in n= 270k no prime.

Gary I have sent you the results 260k-270k some days ago.[/quote]

Thanks. Yes, I got them. I'm updating the web pages now.

[quote=KEP;146025]I'm not going to reserve any of these bases anyway. Even taking it to n<=25000 is more work than I really feels like doing anymore... so I'm wrapping my final works (8 weeks to go at least) amd then I'll decide what (if any) to reserve when that time comes. Sorry for yabbing again, but I made a mistake by simply forgetting how many more weeks of work I've left. Hope you understand and accept my appology... Anyway base 19 Sierp is going to be wrapped somewhere close to next weekend (maybe already the coming weekend) :smile:

Take care everyone and happy crunching :smile:

?? You're doing it again KEP, stating different things on different days on huge efforts. On one hand, you want to reserve something to PrimeGrid level, which will be a multi-year CPU effort, and then on the other hand, you allow the fact that you have a few weeks on your current efforts to stop you? That is, to put it mildly, quite confusing.

Let me see if I have you down correctly now:
Riesel base 3 for k=250M-500M up to n=25K
Riesel base 3 for k<5M (2 k's) up to n=1M (!!)
Sieving sierp base 3 for k=50M-200M for n=25K-100K.
Sierp base 19 up to n=25K. (No primes posted since Sept. 18th so can't update n-range status)
Sierp base 252 k=27 up to n=100M. (No status since Sept. 14th)

The above is a tremendous amount of work for < 2 quads. I believe we calculated the last effort at ~50 CPU days.

If you need some filler work to keep your machines busy, please take something smaller; perhaps some files from the Riesel and Sierp base 3 mini-drives.


Thanks,
Gary

If it wasn't clear, I'm sorry, it all refers to some of the reasons earlier e-mailed to you. I suffered a setback this week, and also I forgot how much more work I've left. You've put my reservations right. Some status:

Sierp base 19 at:

Core 1: 20554
core 2: 20647
Core 3: 21439
Core 4: 22426


Again I ask you to accept my appologize, it all refers to private reasons, and a matter of concentration aswell memory. Expect no more reservations (or at least just ignore them) within the next 6 months, since my intention is to wrap what is now reserved and then leave for at least a while.

Thanks for understanding, and good luck on your own challenges :smile:

Thanks KEP for the detailed status on everything. If you shoot me some primes on base 19 at least up to your lowest core of n=20554, I can update the n-range status also. That's NICE progress on that tough base! :smile:

Gary[/quote]

Regarding the primes for Sierp base 19, I'll verify and e-mail the primes below n=20554, sort them by ascending n value and then e-mail those to you. It is more than 140 primes :smile:

:mad:

I thought that I did Riesel base 27 k=706 to n=300000, but I screwed up. I had to change the input file to ABC format, but used base 26, not base 27, so my results are worthless. What hurts even more is that I didn't find any primes, so I completely wasted my time. I'm releasing this for someone else to work on.

I'm sorry to hear that. Thanks for a valiant effort there.

I have you reserved for both Riesel base 26 and Riesel base 27. Are you only releasing base 27 and still working on base 26? For now, I'm assuming you're only release base 27. I don't show a status from you on base 26 since May 9th.

We have a sieved file posted on the web page for base 27. Whatever you are deciding to release, do you, by chance, have a better sieved file than what we have posted for base 27 or any sieved file for base 26?


Thanks,
Gary

I'm still working on them.

No.
