Looks like we are closing in on the equivalent of t50 which is all that is needed before GNFS. I'll let mine run until morning then switch to something else.

Someone with big iron (Core-i7 or hex-core) can knock this out in under a week. Or someone with distributed sieving or requesting help in a few ranges can also do it. It may not be worth the overhead to try a team sieve, but first a poly is needed. I don't think all the GPU-poly searchers are currently busy. It might be time to make a request in this [URL="http://mersenneforum.org/showthread.php?t=18368"]thread[/URL], or I can. I'm only in town for six more days so I may not be much help on this one.

After the 11e6 level we will need an additional
7550 @ 43e6
14215 @ 11e7
before NFS ready.

I wonder if [B]yoyo[/B] or others would be willing to help with these curves.
