GC_2_809
 

Finally, finishes with a nice split.

I'm guessing around 170 hours +/-10% for a 14.2M matrix using target_density=120 on Core-i5 -t 4.

The log is only for the matrix build.

I love this thread. I remember back in 2007 when it was a monumental achievement to finish matrices half the size of the ones that appear here, after months of work.

And that's almost entirely due to your efforts - I don't think more than a factor three of the wall-time improvement is coming from Intel's extra cores and more efficient DDR3 controllers. My thanks are of course inadequate, but thanks again!

GC_12_222
 

After a few false starts, GC_12_222 has been successfully downloaded and is now in LA. Even managed to build the matrix with a target density of 128.

Should be done on Monday evening.

GC_2_795
 

I downloaded the precompiled msieve v1.52 from sourceforge, but unfortunate it was a 32 bit version, so that wasn't going to work for a 6GB job. The CUDA version (which I suppose is 64 bit) was giving me missing dll errors (the machine has a AMD graphics cards, so that was to be expected). So I reverted back to 1.52dev SVN946 compiled by Wombatman ([URL]http://mersenneforum.org/showpost.php?p=357227&postcount=10[/URL]), which I've successfully used in the past.

I noticed on sourceforge there are numerous improvements with the official v1.52 release, anybody got a link to a precompiled v1.52 Windoze-x64 without CUDA?
BTW, I already checked: [URL]http://gilchrist.ca/jeff/factoring/index.html[/URL] , but those are all 1.51 and 1.52dev versions, so that page might need an update also.

GC_2_795[/B]
Linear algebra started, ETA 110 hours

Reserving GC_2_803 (or C803, as I think Cullen would have called it); I'll try to start it automatically over the weekend, it'll probably take about a week.

I will also reserve L1279 (ETA evening of Monday September 22nd)

Nice split for L1277

I'll do GC_2_804 while waiting on my HomePrimes number to finish up.

L1282
 

A new memory kit arrived, so i'm taking a shot at [b]L1282[/b].

GC_2_795 should be ready in a few hours.
