Good lord, how much RAM did these curves at B1=4.2e9 require ?

A lot....but the system actually remained more responsive than when I ran this huge P1
Code:

4000000000 2086226291290000 3 Frank Schickel The ECM curves took ~6 hours each and >10GB of RAM (check out the page faults; this sucker was swapping like crazy during stage 2!) PS. Andi47, here's the v details for 4.2e9, default B2: Code:
Expected number of curves to find a factor of n digits: 35 40 45 50 55 60 65 70 75 80 9 25 76 255 935 3718 15884 72435 350460 1790896

Thanks. So if I have calculated correctly, we currently have 44.81% of t55.

4 more curves (at a slightly lower B2, 950 curves needed for t55). Would have had one more, but had an unexplained shutdown on the last curve....

It is a workinprogress at this point, but should be usable. Feedback here is welcomed. As for ecm, check out the later posts in the 4788 thread. Also note that gmpecm is available through the repositories for most linux distros, but for some to use it, it is called via gmpecm rather than ecm. For Windows, I've only seen it as ecm.exe.

I finished 1000 more curves @ B1=11e7, B2=1589211473866 (again using B2scale 2), making 2000 total.
I'm stopping my ECM run for now. Weird. My B2 is 1589211473866 (same as the first time I reported) yet the DB changes it into B2=1589211473870. Hardly a difference, but it is curious. Last fiddled with by jrk on 20100916 at 07:57 Reason: stopping
