Kurt Beschorner's page has some data on ECM efforts for base 10 though it looks to be incomplete.

2,1108+ sieving is almost done, less than a week?! Still have Wu's for a few days.

2,1108+ is done. The 159M matrix took a little under 78 hours on eight A100's.

FWIW, Yoyo is still working through the Gang of 31. Only 20 numbers left to process.
I now estimate completion by Yoyo in September 2024 (worst case).

Despite its title this thread seems to be used for general comments about Cunningham number status, and I will make one in reply to the last.
Is it intended that the 'Gang of 31' be the next numbers processed on the big siever, and no others? It seems this would not be possible at current memory limitations; I think the limit has practically been reached with the two base2 numbers in progress now. Further, the 31 combined would likely take more effort than M1277 would, and based on the perennial interest I'm guessing that most people with any opinion on the matter would rather see it tackled first rather than a list set by an arbitrary limit from the 1980s. There are plenty of other Cunninghams remaining to SNFS 335 or GNFS 220, including all but one of the nonbase2 numbers of Wagstaff's Most/More Wanted lists. This is to be taken only as an opinion, and I won't venture to suggest any specific numbers as I'm sure I'm sure all possible candidates are known to those that would make a decision on it.

Besides, if your first quoted statement is true, then M1277 is way way out of reach by Greg and is thus wholly irrelevant; in fact, the limits can be a bit higher than the jobs in progress *and* M1277 still be well beyond those limits.

I am guessing that Greg will select numbers from other bases when the current two are done. Quote:

thus 16 times harder. There will only be 24 numbers to do, many of which are smaller. W1123 and W1124 and 2,2246M will take less than 2% of the effort as M1277. It seems that these 24 would be easier in the aggregate, especially if one uses a factory approach. Quote:

I will leave it to others to decide whether their choices or yours command more respect. And you fail to say what is so <expletive deleted> important about M1277. Is it simply because it has no known factors?? I can name a number of other candidates with no known factors that would be easier. Also, please specify who you think are these "most people with any opinion on the matter". The ones whose opinions matter are the ones providing the resources to do the work. Everyone else is just a bystander.

Just to share with you all Yoyo ecm subproject has been chosen as one of the disciplines for the boinc penthalon. We shall see some nice boost for 14 days.
