I should finish my base-5 PRPing sometime Sunday night. I have a 2.8GHz dual-core Pentium-D that would love to help with this if someone could send me a preprocessed(base-2, all n-values even) file for me to LLR.

Post range you are working on, before starting. So there is no double booking of work.

Thanks for joining the project, attached are the files, sieved to 3T.

edit:- One more thing, is your computer stable? Please run a Prime95 tourture test before starting your range. There is no double check for this project, so all missed primes are missed.

Thanks for the sieve file.


I haven't finished till 1.325 yet, it might take 1-2 more weeks, 200 candidates remaining. (I think I miscalculated)

Once I am done till there, I will stop. I will not PRP any more candidates. It just takes too much time from the fast computers I have. I prefer to put them on PSP. Slow computers take very long to do candidates >1M

As for finding too few factors, I suggest you stop the sieve and PRP instead. P-1 may be better for factoring, you might want to run some tests first.

I don't know how fast Jean's computers are and how far he is planning on extending his k's. It might be a good idea to PRP than sieve.

I've finally finished my sieving reservation up to 5000 billion, Citrix I think you're right that at this point in time it's probably better to just PRP the candidates. attached is the latest dat and the individual files. if I can get a status update (or rather just a confirmation of completion Citrix) then I can get the files updated to the right point as well. I think they're decently far behind at the moment.

I'm also going to be taking a 1-2 week break starting now since I am moving again. thankfully the new place will have a MUCH better internet connection then here!

best of luck,
-Tyler

Default Thanks!

Thank you, Tyler, for the new sieved files! I updated my input files according to them.

For k = 23451, I am now at n = 1430648, no primes, continuing...
(P4 2.53 GHz)

For k = 60849, I am now around n = 1300000, no primes, continuing...
(T2300 1.66 GHz)

I think we have now to be brave while facing this desert crossing...

Best Regards,
Jean

k=18534 complete to 1325000
I would like to put a machine on this project, unfortunately all my computers are turned off this summer, so I am waiting for things to cool off, before I can do any serious prime finding.

I see that you are very serious in your search, and I wish you every success, an oasis before long, in the form of a nice, big prime!

Thanks! Only four k candidates are remaining, but it is possible than one or
more of them would be out of reach for a while... I hope this bad possibility will be disproved soon!

Regards,
Jean

I just started working on k=64494. I don't know how far I get, as I currently only have a single Pentium-M available. But it should help nevertheless.

I wonder why there are a lot more candidates for k=64494 left than for k=18534, given they have almost the same weight.

The wieghts are screwed up due to a sampling error.
