This number can not be prime, as it is divisible by 2. Actually, you can divide it by 2 about a hundred million times, and you still get integers all along, which are still not prime, none of them is...

That is what he was calling "*drastically* lower". This way, lots of tests that won't cause error in the "aggressive" version, would run a lot slower with the larger FFT. Then you would have to find...

Bad news, I matched Qingkong.
Well... it could be worse if would not match any. :smile:

...and mismatched 100M (my residue, 0x268dbd72042d83a1) and of course everything after. Currently a bit below 130M, with yet about 5 hours to go. Assuming I won't match any of the two already done...

Thanks a lot Wayne.
Greetings to Sid, Andy, and co. (i.e. read as swmbo says hi to Jo and all).

Well, that was not fair either, after about 4 hours we are in about 4% and it says ETA 5 days, 1 hour. It seems that immediately after GC runs, P95 (newest) shows a longer ETA. Then the following...

Well, then, ok, 7 digits...

Do you also give them the credit? If they did 57 classes from 960, and you do the rest, you should give them 5.93% of the credit... :razz:

There was no joke on my side. I only tried to help. If you understood it as a joke, then either my understanding, or my explanation, or both, suck.

It looks like his goal is to factor p-1, not to factor n or f(n). More exactly, he tries to factor a factor of p-1 (call it x). For this he first "inflates" x to p, then p to f(n), and tries to do...

Hi Mihai, thanks for the fast answer. I totally agree with what you said. 1M is often enough, and usually for a 100M or 332M test respectively, this will run every 5M or 10M or more iterations, and...

I see a 0-shift not reported, so I grabbed that, with papers in order, for a gpuOwl spin, to return the favor of factoring that 332M. ETA sometimes Friday.
