Here's my poly:

I'll give Ed & Sean a day or so to post any competitive polys, and then I'll queue it on my usual server/port for sieving from Q=20100M. swellman can add it to 15e nfs@home from 100Mup (up? whatever testsieves suggest).

How close is the CADOscore of the secondbest poly from your search? We ought to testsieve your top few maybe anything within 4% of the best one, so 5.6e9 and up? I haven't done much testing of CADO's scoring & ranking algos, this is maybe the right size (in terms of reward vs labor) to see how much 'error' there is in the rankings.

Sorry, no bandwidth. Don’t wait for me. I’ll enqueue the eventual winning poly once a breakpoint for Q between CADO and 15e is determined.

Good finds! I'm having troubles (switch related  maybe heat) that are crashing my CADONFS runs. I will probably not join the sieving in the near term. I'm finding one machine can hang the whole "farm." My best recent scores were 6.553 and 6.695. I don't expect anything better than what was found.

If anyone cares, the usual server & port is running Charybdis' best scoring poly with A=31, 4 threads per process default.
I'll get his secondbest fired up shortly on a different port and see how ETAs compare in the morning (lazy man's testsieve). 20 threads on each, on a 20core machine.

Yep! My records suggest it's largeprimesize choice and siever area, but lim's might go into the calculation of Bf and Bg too.
