There doesn't seem to be a great deal of interest in this project at the moment. I don't think I'd be capable of doing postproc, but I can add some relations. I've started the collection with 8890M, which will be finished soon, I think.
How much RAM is needed for this c162?

Something went amiss with one of my programs here and I have a gap in my 88M90M region that I need to fill in. I should be able to have it (and the offending program) squared away by tomorrow. I'll run 8688M after that. With a small turnout, I imagine this will be a lengthy factorization. We'll see if my attention span is that long...

I can do the post proc, presuming the sieving takes longer than the SNFS 221 I'm currently doing.

Thanks for the offer. At the rate rels are being compiled, it will probably be a while... Actually, if my attention doesn't wane and I can settle out some variations between machines here so they're a little more efficient, I might be able to do the sieve range in 23 weeks. I started high so others could grab the low end, but this sequence isn't all that interesting right now.

It looks like yoyo@home will run out of curves in a day or two. I'll pick up a few M Qs, say 7680M unless someone thinks I should do a different range. I'll check back in less than 24 hours.
