Gonna try secondpass on my xeons and sieving on my XP for a while until everything settles down. Hate doing duplicate work.

One user outperformed the ARS team yesterday, all by his/her lonesome. Today he/she slowed down a little, but would still have come in third place as a team.

[ShoeLace]

did you see they have 14140 pending tests ?!?!?

[Nuri]

With account age of 227 days and 19 tests completed overall...

[Joe O]

I just barely started on my new updated p1 factoring reservation and looking at the stats it looks like in a day or so it will be passed by. Should I even try to factor anything and wait how the new sheriff in town produce or what? Any ideas?

Give it a day or so until things sort themselves out. If it is just a runaway client (or something) these tests will be re-released. If it is really a massive influx of computing power, then there is no way for P-1 to keep up with it.

Sieving anyone?

Thanks Joe, its about time for sieving again anyway. Was just waiting for the new siever, guess its working fine now.

just got an Q
if we can sieve together with PSP, can we p-1 together?

Nope.

Firstpass at SoB is at nearly 15M, while around 5M for PSP only. And at 5M, P-1 isn't worth it, fortunatlythanks to the deep sieving.

thank you.

and another question. I try to make p-1 for riesel, just to see some stats for my team.

and latest version of prime95 doesn't "continue" after makewdt.exe

what's wrong with it and what version do you use?

[glennpat]

I'm been running linux lately so have not been using Prime95 much. The newer Prime95 version 25.3 has changed some on the file names. From the whatsnew:

Several files have been renamed so that they are not changed by Windows
save/restore. Prime.ini is now prime.txt. Local.ini is now local.txt.
Worktodo.ini is now worktodo.txt. The primenet.ini file has been
deleted - it is now a section within the prime.txt file.

hmmmm.... maybe I should check this out.

P-1 for Riesel will not be worth the CPU-cycles: They have sieved deeper than we have, and have even lower n.

This is make just for fun. I want to see team Ukraine in stats, don't care about place or scores, just presence. And also try to understand how to run p-1, this knowledge can be useful in other projects.

Your results are going to be useless, given the advance of firstpass, see here or here. A reservation above 15M will make more sense. H.

PS: Yes, I agree, somebody could clean up thread. H.

Won't they still be useful for secondpass, though?

Yes, but the whole purpose of P-1 is to save tests at a last stand, isn't it? H.

[Max Dettweiler]

I would think that even if the number has been tested once, a factor for that number can still save us from having to do the secondpass test.

That's right. Yet, it will happen only in a few years, and by that time, there is a good chance that a prime will be found or that sieving would have found that factor. And then, P-1 is not superfast. By the time it takes to find this factor, one could have done this one LLR test; but not two.

So, if one would want to look for factors of Doublecheck numbers, one would do that right before doublecheck hits them, and then again, one would not do it at all, because you are better off with LLR directly.

I hope I look not too wise-assed now... H.
