I was able to get a preliminary peek at the current candidate polynomials and it doesn't look promising. The best so far is <9e15. cownoise: Code:

My best from CADO is 9.61e15 according to cownoise.
I'll testsieve it against the Gimarel polys, but I expect inferiority.

My run has finished and nothing better showed up.

Gimarel's second poly proved fastest, and with highest yield. A 32/33 LP hybrid appears a bit faster than 33/33, and produces less data, so that was chosen. I did not trialsieve 32/32.

The C196 is done, next blocker is a C164 which I've ECM'ed a bit past T50. I will CADO it starting tonight, unless someone with more hardware takes it first.
I expect to need about a week to factor it on 20 cores. Edit: I'll post the C196 log/info to the 16e thread tonight also. Last fiddled with by VBCurtis on 20201222 at 20:54

Knowing Ed and his farm, two days is all it will take to sieve!
I got to about 1.2t50 on the C164, tried a few hundred curves at 15e7 before I saw Ed's reservation.

I was optimistically thinking tomorrow evening, but it is still in size opt polyselection. In checking, I found that I do not have an "Improved" c165 params file (hint, hint).

Edit: I do have a snap0 recovery script, that picks things up if something crashes, but I'm a bit leery of changing things once it's underway, unless necessary. Last fiddled with by EdH on 20201223 at 03:25
