I consider quoting yourself to re-ask the same question demanding. Nobody answered you the first time because nobody has an answer yet; when you quote yourself to ask it again I feel like someone has to respond to keep you from doing it over and over.

You're welcome to take on some poly select or test-sieving to reduce the load on some of the other volunteers around here. If you're in a hurry, feel free to add your labor. CADO does cpu-based poly select as effectively as msieve-gpu, and test-sieving is an area your expertise surely would be useful in.

And I consider making personal comments in a purely technical discussion to be obnoxious. I'd make a personal comment now, but I refuse to lower myself to your level.

(1) I am already running ECM on 2^(4k) + 1. This is how I contribute.

(2) I am not allowed to install outside software on machines at work without a
long and involved process to get special permission. I would need to justify it by
giving a business reason for doing it. We are behind a very strict/tight firewall.
I don't participate in NFS@Home for the same reason(s). Remote work
assignment software can't get messages through our firewall. I can't use other
people's desktop computers. I have a grand total of two machines available at work:
one in a public conference room along with my personal laptop; 10 total cores.

(3) Does CADO even run under Windows? The only Unix machines available here are all reserved for project work only.

Also, I'll try to CADO both today to get better results.

Can the CADO server be used for poly stage? If not anyone can guide me how to manually run CADO poly search or is it better to use msieve. TIA.

Once the filtering is complete on 2330L and the server isn't hammering swap, I can set and run a job for poly select. When I get it set up, I'll post the port number on this thread.

Good idea, sir!

To use CADO for poly search only, you can add the switch "tasks.sieve.run=false" to your command line.

This will break out of the python script. The poly file will be in the temporary directory that CADO used. If you plan to use the poly elsewhere, you may need to edit it into the "elsewhere" format.

I actually have a hybrid script that uses CADO for poly search and sieving, but uses msieve for the Linear Algebra and later. I use "tasks.filter.run=false" to stop it after sieving.

Edit: Missed Curtis' post...

I'm running polyselect with the similar parameters as for 2,2330L.

While I await more RAM, I've started a CADO server for polyselect for this number.
Point your client to the usual address as used on the 2330L job, with port number changed to 44400. The job should take about 8M thread-seconds, so just 2-3 days.
EDIT: reserving degree 6, admin 1.05M, admax 20M. For those curious: nq=6^6, incr 4620, P=8 million.
