For those who have continued interest in 3408 and 3366, future work on these can be done on this server, with clients shared by prior arrangement simply by sending me your IP address, and I'll send you the address and port I'll be using for any CADO work that's public-facing. Poly select and sieve are distributed simply, while the matrix is solved on the server alone (an 8-core Xeon of the core2 era, with 24 or 32GB). With a bit of assistance from Rich and Sean, we should be able to knock out sub-185 digit blockers limited mostly by the time the matrix takes!
Any windows client available?

The CADO site indicates that the client software and "las" siever app can be compiled in Windows, but I haven't tried myself (and the instructions appear, um, sparse). If you try it, let us know about your success!

Default C166 @ i1679

Looks like yoyo is completing 0.5t55 (9000 @ 110e6) which might be enough to start poly selection.

Here are a few polys to set a baseline. Nothing to write home about.

This concludes my search, at just over 1.6 million core-seconds.

Thanks to Max clueing me in about http://myfactors.mooo.com/, I have scores for the polys I posted.
The first has optimal skew 5119078.6 and msieve E-score 7.119e-13

The second has optimal skew 2436168.8 and E-score 6.894e-13

The first poly breaks the C166 record by a tiny bit. :)

@VBCurtis
If you rerun your first poly through msieve, E score will be just another bit higher:

i1681 has a c134. If nobody claims it in the next 4-5 hours, I'll be cracking this overnight.
Running ECM at B1=3M+ this evening.

Done. My last few curves (@ 11e6) caught the p49.
And I am done with the number. Leaving first thing in the morning.
