This is from near the end of a block on this system:
Code:
total yield: 20027, q=25744079 (0.64431 sec/rel)
My 32-bit Vista system runs a hair faster....

It looks like I'm getting around 14 millions relations a month, so ~7 months to get to 97 million.

We'll see how it goes. I've got one more core I could put on this with a little effort. I just haven't got around to it yet.

Actually, by that time, I hope to have added a quad-core to the stable, so I can probably actaully shave a month or two off that by myself.

I will join sieving when the driverless sequences hit a driver (or terminate) and the subproject-sequence exceeds 110 digits.

 2010-10-10, 17:46 #18 bchaffin   Sep 2010 Portland, OR 37110 Posts I'd like to contribute, but I'm pretty new to factoring and want to make sure that I know what I'm signing up for (and that I'm doing it right). Schickel says blocks of 10k take ~3 hours, but bsquared says he'll do 7.2 million in one day... so bsquared, do you have ~100 cores? Anyway, if all I need to do is run that sieving command for a series of ranges, then cat the results together and post them somewhere, I think I can handle it. :) I'll take 30M-31M first to see how it goes.

I have 50 cores, each of which is twice as fast as schickel's... so you were close ;).

Whatever is easiest for you to manage.

And on the FTP front, I don't know if it's me, my router, or the software, but I couldn't get a connection to the server I tried. I'll try another one, but until I can get something running, maybe just post files on sendspace or rapidshare for the time being.

Sounds good. (Nothing like diving in at the deep end!)

If you have any questions, don't hesitate to ask, we've great support available around here.
