Folks probably know this but 2,1084+ has completed 0.5t65, and 2,2150M is currently working on the same level and should complete 0.5t55 in 7-10 days. I’ve queued up both numbers for another 12,000 curves @ B1=850M. Once that is done, I’ll ask Yoyo if I can kick the job up to 24,000 curves each just to finish it off.

That said, it seems as though Greg is getting ready to queue one or both of these numbers. When he does, I will cease adding more work to the queue and advise Yoyo.

Next up for ECM is 2.1165+ (only remaining GNFS and has 43% t65 so far) and 2,1157+. A full t65 will take us into spring at current rate of progress.

Minor addendum: This is only with respect to work that YoYo has done.

If one adds prior contributions from Bruce Dodson, EPFL, Peter Montgomery, me, et.al.
the total work adds up to quite a bit more than t65.

Of course! I meant no slight to the previous work, just talking about the work associated with the recent initiative. Sorry if it seemed as if I was ignoring all the contributions to the Cunningham project, certainly not my intent.

No, it did not seem as if your were ignoring previous work. No slight taken.

I just wanted to make it clear to those who may not be following the work that
you were referring to current efforts only. People may not know that a lot of work
has been done previously.

I'll queue 2,2150M tomorrow. As Bob suspected, 10,313+ will finish soon. I've had little time to devote to the project since the semester started, so things have largely been on autopilot. I'll devote time to bring everything up to date shortly.

Let's not forget 2,1144+.


2,2150M can be removed from the queue. Greg says he will start it shortly.

Tracking. Request made to yoyo to kill any unstarted work on 2,2150M.

2,1144+ is on my radar.

ETA: Yoyo has now killed any future ECM work for 2,2150M. The current WUs can’t be recalled and results will trickle in over the next week or so.

Hmmm. From trial sieving, 2,2150M will take less than a week to sieve.

2,1084+1 has even more ECM completed than 2,2150M if you are looking for another NFS candidate for factoring.

I am very surprised. As a sextic 2,2150M is 1075 bits. 2,1076+ took a month to
sieve. As a quartic, it is C259 which I thought would be harder than the sextic.

If we can do quartics in this range, 2,2230M becomes of interest.

Note also that 2,2210M might be easier as a quartic SNFS than via GNFS.....
