Taking the CHG-KP candidates 001-020 :smile:

I'll take 184-187 for my Ubuntu box.

Taking 021-040.

Taking 041-060, [COLOR="Blue"]... plus 061-062.

Now, starting from file 063, [B]all you need is [STRIKE]love[/STRIKE] LLR[/B]. (Because 10^a-10^b-1 is proven by LLR when b>a/2.)
Very low threshold to enter the race![/COLOR]

Taking 063-099

No primes yet, Serge?

180
181
182
183

for me :smile:

It's one tough mother! I am running out of work ^_^

Taking 100-120.

[COLOR="Blue"]Done with 1-120 (attached).[/COLOR]

Taking 121-140.

Taking 141-170.

I'm going to go ahead and give up 184-187. They're going to take way too long on my older box, and I don't want to hold things up.

And just to save a little time, here's the completed numbers from 184-187. Only a couple dozen, but no need to redo them. None were primes.

Thanks :tu:

You bet! Sorry I don't have a faster way to process these. I was hoping the Phenom II X4 would be sufficiently fast, but it was taking ~6 hours for each number.

Yeah they are taking 1:20 hours on my i7. Generic modular reduction is really slow compared to special. :smile:

Taking 171-179.

I'll take the last four, 184-187.

Note those files have been partially done. See wombatman's post with its attachment.

Thanks, I've deleted his completed results from the input files. Just a single i7 core presently for them, so about 2 weeks per file.

Done with my reservations. Also included are my own lightly sieved files "-010... -001" (PRP-candidates; some of them could still be provable: this depends on smoothness of n-m and occasional deeper than average factorizations of 10^(n-m)-1).

Thanks a million, Serge. This exponent has been extremely disappointing, considering 15% or so was left after sieving. Let's hope either VBCurtis or I get a consolation prize :smile:

That would be great! -- I've used up all my luck on previous expo :rolleyes: so, what's fair is fair!

No consolation prize for me. 184 to 187 complete, no primes. Most results attached; a few dozen tests were done on another machine and are not included.
