There is an error in 14e detailed status page, for GW_404 it should
be P80*P154 not P50*P154 ;)

Ed: fixed

C257_135_82 linear algebra complete (see http://www.mersenneforum.org/showpos...&postcount=232 )

188.4 hours on six threads i7/4930K for an 18.24M matrix built with target density 120

C261_139_75 relations currently downloading and should start tonight.

(9/9 morning) 406.9M relations / 319M unique is not enough to build a matrix at td=120 for 261-digit SNFS. Doing 10% more sieving.

Reserve GC_5_343; this really should be done over the weekend

frmky · 2015-09-10, 05:02

I've taken W_795 and GW_3_502. Both should be done tomorrow.
