2,1097+ is currently sieving, and assuming nothing goes wrong, Greg has announced plans to tackle 2,2194LM.
Again assuming no problems with 2,2194LM, I presume Greg will consider 2,2206L, a SNFS 332 difficulty composite. By coincidence 2,2206L should be starting ECM in the coming days, so if Yoyo doesn’t find a factor perhaps Greg will take it on. 2,1109+ is now enqueued with Yoyo, follow its progress here. I expect this job to actually start ECM in late January. I am planning to next enqueue 2,2222L with Yoyo@Home. I’ve no notion whether NFS@Home can handle a SNFS 334/GNFS 228 job but at least we can meet our due diligence wrt ECM. Slowly working through the Gang of 31, er 20something.

The one big trick remaining to extend nfs@home's reach is to use 3 large primes on both sides. A 50% yield improvement would add a few digits of range, making high 220s or low 230s in reach. It may even add speed, since such small lims are used for these jobs.

Do you mean 2,2222L?

Does that work with lasieve5? Last I tried it ran significantly slower and sometimes stalled, but I might have been using lasieve4 at the time. I'll try it again. I also plan to try using 36bit LPs on one side and push msieve filtering to its limit.

I've been testing 3LP with much lower mfb's than usually used say, 90 and 102 for 35/36LP job. I don't see nearly the speed hit that e.g. 103/105 would be, and I get quite a bit better yield. I think I tried this on M1277 first, then on one of the GNFS225 polys from the recent thread; I don't have records handy, and I was testing with CADO rather than ggnfs.
There should be a transition area where mfb 9092 is faster than mfb 70, but mfb 100 is slower.
