YuL: you have some pretty impressive compute resource there! Would you be able to run for ~100 wallclock hours to deal with Lucas(1321) ?

Amazon EC2, 100 hours of 4x r4.16xlarge would cost me ~480$ :).

I'm postprocessing C213_142_112 with 449159757 relations (I started it with a few relations still pending to be reported to NFS@Home). At first I tried a target_density of 120 (a standard value for me), but it failed to enter the LA step. So I tried it again without specifying a target_density and it has begun LA on 29.7 million dimensions.
Only thing is that it's estimating about 30 days on my i54670K to complete linear algebra. Is this to be expected, or is there something I should do to speed it up? I don't have a problem letting it run, just want to know I'm not wasting my time. I don't think I've done a job this big before. Log attached. Last fiddled with by MiniGeek on 20171015 at 12:31

That said, a SNFS 263 is never going to be a one week job on a single machine. Good luck!
