Now that the matrix for 2330L is nearly complete, and I'm looking for a next Big Project, I notice we never got 'round to poly select for this candidate.

Who is interested in a team-CADO (I=15, ~3GB/process) project to factor this?

I plan to get started on the poly select this weekend, using CADO. Any GPU-msieve searchers should reserve a c5-range per usual.

The RSA-240 factorization announcement implies that CADO has gotten a fair bit faster during 2019; I'm not yet sure which of the speed improvements are from better param choices and which are from siever improvements, so I don't know just yet whether we're looking at a 25 core-year sieve job or 40. For reference, we did 2330L, a c207, in just under 100 thread-years; but most of those were hyperthreaded so call it 50 core-years.

Did the forum polyselect for 2,1165+ or 2,2210M? I don't believe so.......

Curtis, I’m always up to a new challenge, count me in, not sure about my friends at SETI.USA and The Scottish teams.

I'm with Bob here.

Let's finish the "traditional" Cunningham tables asap.

2,1165+ is C217. Could someone confirm that Greg will run this?
This "should" be above the cutoff between deg 5 and deg 6, with CADO's better deg 6 polys. I'm game to set a new record poly score.
I'll start a thread for poly select coordination for 2,1165+.

However, poly select isn't a Big Project. I'm still looking for a C198-C205 to run as a CADO-team-factorization, and the number from this thread title fills the bill as well as any I know of. Is there a C200-203 Fibonacci number available instead? I'd like a slightly smaller candidate, to gain experience; perhaps one Fibonacci and this C204 before we attack something C210+?

EDIT: 2,2210M has a poly select thread, and quite a bit of work done. The last post in that thread stated Greg will solve it by SNFS. I thought that closed the matter...?

2,1165+ , sieve completed by NFS@Home.


Sieving: 2,1157+
Queued: 2,1144+, 2,2158L, 2,2330M

Sounds like Greg is already handling the two proposed alternatives, so I return to starting poly select tomorrow on 3,748+.

I would get on touch with Greg regarding 2,2330M because it is queued on the status page but not on the wus side (generation side). Is he expecting a poly from here?

I never saw 2,1165+ running. I think Greg skipped over it to do 2,1157+.
The jobs seemed to go directly from running 2,1084+ to running 2,1157+.

Perhaps I am blind???

I had previously asked about 2,2210M. It is not currently queued on the status page.
I was under the impression that polyselect had been started, but not finished.

Thought I have seen it a couple of weeks ago whilst crunching for NFS@Home but I might be wrong.
