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:

Batalov 2015-01-02 07:24

Taking 171-179.

VBCurtis 2015-01-02 08:43

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

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

VBCurtis 2015-01-02 17:37

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).

paulunderwood 2015-01-02 18:09

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:

Batalov 2015-01-02 18:36

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