therefore, that Greg skipped it for the time being because he was lacking a polynomial.

I also believe that there was some uncertainty about whether Greg would do it via GNFS or SNFS.....

I’ve reached out to Greg, inviting him to provide clarity on the current Cunningham effort, i.e. what does he need done?
Helping Greg with postprocessing is a worthy effort, but few of us have the resources. 3,748+ c204 needs to be factored sooner or later, but I will help poly search anything that needs it.

We still need a poly for 2,1165+. Postprocessing is quite a bit behind, but I will be spending more time on it once the semester ends. Assistance is welcome, but I know few have the resources needed to process numbers of this size. I still need to trial sieve 2,2210M with a quartic.

Greg
Every time you come across a matrix 50M or smaller, please offer the job to the forumites here. If we help you out with the smaller jobs, you can use your resources more effectively. There are a fair number of us with 32GB available for NFS postprocessing, and I think <45M matrices fit in 32GB. Fivemack and I have larger memory machines. I'm willing to solve a ~50M matrix here and there, perhaps 50% of the machine's time. Let's get to poly select on 2,1165+ before we tackle 3,748+. I have a poly select job running for 3,748+ so I'll post a starter poly in this thread in a few days, but then I'll move to CADOsextic on 2,1165+; let's start a new thread for that poly select job, our largest ever at C217!

Greg,
How are you in terms of NFS@Home hard drive space? I’ve not been very active on getting more CPU power to the project due to the post processing backlog. Also, you might have noticed but from time to time we are invaded by forum spammers. Messages have been hidden but I think you should block their IP. To all, what about a crowdfunding to build a machine to support Greg? Or can we have one linked to NFS@Home, I wouldn’t be surprised to see members of the project donating to it, I would and know a bunch of guys from teams who also would. What about adding to the project a progress to the outstanding numbers to finish the "traditional" Cunningham tables. BOINC clients like to see goals, fancy dashboards with progress and target.

Happy to contribute to crowdfunding a machine for Greg
I also have an large ram box (96GB of DDR3) I'd be happy to donate time on if needed.
