The CADO folks have a week or so to beat Gimarel's nice poly (about 10% worse than RSA-200 poly, so already a very nice C201 poly).
I'll test-sieve late next week and we'll queue the job on...

My two main machines are both solving matrices right now, so I'm not available to poly select for a week or so.
As usual, happy to test-sieve our candidates for placement on the f-small queue....

What you've got there is nearly exactly my HP Z620 workstation. They go for about $1000 on ebay in similar configuration (though not with dual 4TB drives, more like a 1TB or 750GB).
I'd trust a...

597M relations built a 34.4M matrix at TD 100 overnight.
I lost internet connection to the CADO server overnight, so we quit serving workunits at 615M relations. That'll be enough, so we're...

578M raw relations got me 391M uniques, and a 39.98M matrix at TD=84.
There was a deficit of 27M in relations vs ideals in the first step of filtering, so I'm continuing to sieve. I think 610M or...
