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.

6000 curves at 6e7 done, moving up 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.

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 5-7% longer time per curve but 10% fewer curves needed for T60.

I'm using 128 cores - decided to put the CADO 2LP bound experiment on the backburner for now. By the looks of it mine are faster than yours?

Well spotted! I'll switch over on the machines which have enough memory per core.
