YoYo can stop further ECM work on 2,2126M. NFS@Home has started sieving it.

Isn’t worth to keep it still active for a further couple of days since most of the NFS@Home users have queue set up to at least 3 days and sometimes with additional days. My case it will take me 2 days to start processing 2,2126M.

No. Further ECM is pointless.

Ok, noted. Thank you.

I have let yoyo know about 2,2126M. Only he can kill it.

Please let me know when sieving starts on 2_1084+1 and 2_2150M and I will ask yoyo to kill those jobs as well.

I don't know what Greg will do next. 2,2126M should take ~2 to 3 weeks. He may then
do 2,2330M via GNFS. I believe that the forum has selected a polynomial for it???

2,2150M will take a month to sieve and 2,1084+ should take 6-7 weeks.

We don't really need to manually kill the current work on 2,2126M since there are only
a couple of hundred curves left. It should suffice to merely remove it from the queue.

It’s all good. “Killing it” simply refers to stopping new WU from being distributed. I suppose there is a vanishingly small chance of a factor appearing before the job finishes completely.

No worries on the other two Cunningham numbers. I don’t have visibility on Greg’s queue (other than [url=https://escatter11.fullerton.edu/nfs/numbers.html]here[/url]) so I would appreciate any news. Until then, I will keep up with yoyo’s ECM efforts.

The only work around to get access to what is being sieved and boundary is go to one of the hosts at [URL]https://escatter11.fullerton.edu/nfs/top_hosts.php[/URL] and look at the tasks. Right now the sieve wave for 2,2126M is at S2M2126_102082_0 of delivered.

Sam Wagstaff just got 2,2386L via ECM.

[Just in case anyone was wondering whether the remaining composites are worth
attacking with ECM]

2,2126M should finish sieving in another few days. I estimate ~ 5 days.

The status page does not indicate what will be done next. It's been two months
since it was last updated.

Allow me to ask:

Has the polynomial/input file(s) for 2,2330M been sent to Greg?

It's also been a long time since the last LA result. Based on past efforts I would
have expected 10,313+ to have been finished by now. I assume the Greg got hung
up for some reason......[If indeed 10,313+ was the next target].

I am just ~two weeks away from finishing my ECM B1 = 3G pass through the
2,4k+ table. [1000 curves on each]. 2,1180+ is in progress now.

Coincidently I will also be retiring from work at about the same time that 2,1180+
finishes. I will lose quite a few cores when I do so.

No, I haven't had much time to test-sieve. I expect I'll need this weekend and next to get it done, but no promises.
