Well, I took 996666 from T865 (T=term) to T880 (after a proper reservation, as you advised me before), it is a "good" sequence, never made problems and gave me to factor only composites below C102. Still going on it.[/quote]Good to hear that things are going good.[quote]I use to report the factors as I find them. All is manual job, I don't like the fact that I can't (or I don't know how to) customize programs like aliqueit112.exe to launch the factoring program I want, with the parameters I want, so I do the job manually when I have time and a free core for a couple of hours). This is in fact good, as someone else (the server, yoyo's boincs) could find factors for the small composites (when and if they appear) faster that I can do, but is bad because they step on my fingers and we do the same job twice.[/quote]Well, one trick you can use is to keep the .elf file locally, and only report the factors occasionally. The FactorDB can handle the lines of an elf file through the "Report results -> Report factors" interface (the type is "Multiple factors per line, base 10".)

If you care to post details about the problems you're having getting aliqueit going, I'm sure that someone would have a setup close enough to yours to help get things squared away.[quote]That is why I posted, I just want to let you know FYI that the fact you mentioned, about the factorDB not lending out composites from proper reserved sequences, is not quite true. As I expected, last evening someone (maybe one of yoyo's boincs) factored the C82 of T879 and reported the result much faster then I could . No big deal, if the sequence is making steps, no matter who pushed it forward. I will jostle it when is floundered. :smile:[/quote]It is a >99% probability that it is yoyo's workers catching these, since bchaffin's workers check the reservation thread while yoyo's workers only work on the smallest open composites....

Releasing
321660 after a short downdrive it now has 2^2*3*7

Taking
590556

Releasing 590556, a quickie:
started with i2303: 2^2*3
lost the 3 at i2314
lost a 2 at i2318
now: i3060: [B]59![/B]

taking: 787920

fivemack 2011-10-01 18:36

IE you've managed a sequence termination. Superb!

reserving 347664

bchaffin 2011-10-05 17:30

252330 is done. It lost and regained the 3 many times, and even had a brief downdriver run, but now it has 2^3*3*5.

Edit: looks like my workers already finished off 412944 too (it now has 2^3 * 3^2).

Reserving 429264.

[QUOTE=bchaffin;273492]Edit: looks like my workers already finished off 412944 too (it now has 2^3 * 3^2).[/QUOTE]'Course you could try to manage an escape from 2^3 * 3 while the 3 is squared.....(although looking at it, there were plenty of chances that haven't borne fruit....too bad.)

I am playing with 665400. Not sure if I will take it to sub-project completion or not. I'm setting up a "new-to-me" dual core machine...

Yeah... but there are so many other ones to do instead. :smile: Maybe the next subproject can tackle ones like this -- and maybe by then my workers will have gotten to c109s and pushed this one a little farther.

There is a subproject for this. I think this subproject is probably better as you often gain 2^2 * 3 when losing 2^3 * 3.
