[QUOTE=henryzz;166717]i have previously set up a personal ecm server so feel free to pm me
i think the latest version of ecmnet is 2.7.2[/QUOTE]
Okay, thanks! I'll drop you a line if I run into any problems. :smile:

[quote=schickel;166724]Does anyone have binaries that will run on Win98? I use this machine for running an ECM server and until I update my network, it's the only one I can put facing the 'net. (I'm still running 2.0....)[/quote]
will binaries compiled with cygwin work?

Okay...polynomial selection for the C132 has completed! It's getting late now in my time zone so I may not have time to get a reservation/info post done tonight, but at any rate I should have it up sometime tomorrow morning at the latest. :smile:

[QUOTE=bsquared;166491]There are two 64 bit gnfs-lasieve*Ie versions, one with and one without assembly optimizations. The one with is approximatly twice as fast as the one without (and twice as fast as the 32bit version), but AFAIK, is only available on linux.[/QUOTE]

Do you (or anyone) know where I can find the asm version? The code at [url]http://ggnfs.svn.sourceforge.net/viewvc/ggnfs/[/url] doesn't seem to have any 64-bit asm in it apart from a tiny snippet of inline asm.

As detailed in the [url=http://www.mersenneforum.org/showthread.php?p=167954]group GNFS thread[/url], line 2369 factors as:

2^4 * 340752666907 * 116238860920079121381876555229229980591511378427190831 * 2042984904229740263571126912422221015960751979074301306917503575020558507237161

I'll crank as many further lines as I can with Syd's workers.

Okay, we now have a C102 on line 2375 that survived ECM up to t35. Any volunteers? :smile:

Here's the composite:

I'll take it. It will be done in the morning.

I reckon half-t45 on this one. Then we would have the question of whether to do the poly search with msieve or pol51 as this is the level where msieve starts becoming worse.

[-]Try both and compare the polynomials, and send the results to JasonP.[/-]

Edit:

no. Grab the factors found by Syd's workers. [url]http://factorization.ath.cx/search.php?id=28141070[/url]
