New 15e number queued
A new C182 (the XYYXF number with the highest GNFS:SNFS difficulty ratio) is queued up on 15e; thanks to ChristianB for using two weeks of GPU time on his GeForce 750Ti to do the polynomial selection. 2340_742 will start linear algebra tomorrow. 15 Jul 2015, 20:52:50 UTC · Comment


10,359- factored
10,359- has been factored by GNFS. It is the product of 101- and 108-digit prime numbers. We still have lots of sieving to do for 6,490+. Thanks for your help! 4 Jul 2015, 3:35:35 UTC · Comment


16e status updated
The long neglected 16e status page has been updated with the 6 7 factorizations completed so far this year. We will shortly have an 8th completed. Thanks for all of your contributions! 2 Jul 2015, 22:33:37 UTC · Comment


BOINC code upgrade
I'm working on transitioning the project's per-app credits from my custom code to the official BOINC code. Various credit- and badge-related displays may be a bit broken for a bit. Sorry for any inconvenience!

Edit: I think everything should be working now. Please let me know if you find anything broken by leaving a comment on this post. Thanks!

193-digit GNFS coming atcha!
After five GPU-weeks of polynomial selection and a thousand CPU-hours of trial sieving, I've queued up a 193-digit GNFS from the aliquot-sequences project.

For this one I choose parameters to run through c5=1..10^7 in five GPU-weeks, which came out as stage-1 norm of 1e28 and stage-2 of 1e26. The best polynomial came from the first block, with c5=286440. Average yield (over Q=5e7*N .. 5e7*N+1e4 for N=1..8) is just slightly under 1, so I'm sieving 50M..500M to get a good number of relations.

There will be a 190-digit coming in about another three weeks when the polynomial selection's finished.
