Index 2218 C197 has been cracked and sent to DB. Matrix was just over 41M in size, so it took a while.
Now at 2220, a C135 that I've fed to CADO. I'll have factors in about 9 hours, just before bed.

C135 done. Now i2221 at C141, which will take me a bit about 18 hrs to GNFS.

C141 done.
Now C183 on index 2222. I've done about a T40, with 2000@2e7 (roughly a T45) scheduled for the next few hours. T50 or larger curves welcome. If you crack it, you are welcome to try the next index too. Post your counts and B1; we should do about a T55 on this one before 15e. EDIT: P41 found, C142 entering GNFS now. factors in ~20 hr.

C142 now finished. Now C196 on i2224.
t40 complete, t45 will be done in ~4 hrs. Y'all are invited for t50 or larger curves!

i2224:C196 continues.
1300@2e7 complete, just over half a t45. Moving up to 6e7 and 8e7 curves; I'll get half a t50 done, and then jump to 15e7.

I did 800@6e7 and 650 @ 8e7. We're at about 1.5t50 combined.
T60 is about right for total effort here? I am moving to 15e7 curves presently. About 10,000 of those gets us T55 from here. I have 2000 queued over the next 18 hr or so; I'll step to B1=300M next once we're near a T55.

0.31 rule would suggest a little more than t60; we did 1.5t60 for the c197.
12400@15e7 done. Running curves at 4e8 now  32000 of those is a t60. Last fiddled with by charybdis on 20201022 at 17:45

I got 1440@15e7 done. I ran on 30 cores, which makes your curve count... staggering! Our combined effort so far is about 16% of a T60.
I've shifted to B1=42e7; 4e8 uses k=6 and less memory, while 420M uses k=2 and more memory for a 1/3 larger B2 value. About 57% longer time per curve but 10% fewer curves needed for T60.
