Roger, thanks. I'm tuning yafu now, and will do a test run on my current composite next.

Thanks again, everyone, for your patience.

Good job, welcome to the club!

It seems like you are interested in aliquot sequences. Once you get the aliqueit running, you will have to get a good feeling on how the reservation system works. For a TL;DR version, I'll say just state a few casual pitfalls: 1) not every sequence than no one is working on needs work. Some of them (after a few iterations) join in the path of another sequence. 2) as a consequence, it may be not a good idea to immediately go into the range above 1,000,000 (or else one needs to have a good chart of what needs work and what doesn't). But I see from the reservations thread that you got a grip on that.

Got it, thanks.

Yeah, I'm currently running on an ECMed c109 from 419760:628.

The only question is whether I run out of patience before the sequence runs out of 2^4*31. I suspect the answer to this question is "yes", but the fundamental properties of numbers are notorious for ignoring prayer :D

EDIT: Also, I'm finding relations, so things appear to be working correctly. Is there any way to see the number of predicted relations needed?

As a quick note, after completing polynomial selection (which I was so unfamiliar with the output that I mistook it for sieving), yafu complained about

Code:

could not open rels0.dat for reading

Using these binaries worked fine (I'll look into efficiency later). I just had to give myself execute permission on them.
