4,411+ poly
 

Next smaller GNFS number (C166) in the most wanted list (GCW).
Need to check if enough ECM has been performed.
The next smallest GNFS number is reserved so this concludes my work here - for now. :smile:

Pre-reserving that one too for NFS@Home's 14e, pending the confirmation of the amount of ECM work run on this number.

The 15e queue is getting relatively empty; has anyone got a C18x with polynomial search completed or an S27x lying around?

[QUOTE=Dubslow;428599]At any rate, Aliquot sequence 4788 is nearing readiness to begin GNFS on the extant C195.[/quote]

This is a challenging 15e number (that is, the linear algebra will take months on my biggest machine or a week on Greg's 160 Xeon cores).

I have finished GPU stage-1 (10k curves at 6e8) for 149^91+91^149, so will start GPU polynomial selection for that C190 in a week or so when the stage-2 has finished.

See [url=http://www.mersenneforum.org/showpost.php?p=429211&postcount=435]this post[/url]. Wombatman has a candidate for 15e, as do I.

OK: HP2_4496_296 and C219_145_66 test-sieved and queued up

Fivemack - thank you!

Lionel - in case of the 14e queue runs dry, here are three more candidates (all ECM'd to t50 by yoyo@Home). I'm in the process of running ECM @B1=11e7 on a list of more difficult candidates but those take time to preprocess.

C171_142_35
C188_140_116
C205_121_72

Thanks a ton!

A few more nominees just to keep the grid fed past the weekend...

C186_126_110
C208_139_42
C175_148_42

All have survived t50 by yoyo@Home.

If the 14e queue needs more substantial composites, here are a few more homogeneous Cunningham numbers. They have all had 10,000 curves with B1 = 110e6. Polynomials available on request.

[QUOTE=XYYXF;428876]Ryan Propper ran some ECM curves on them, possibly a few hundreds at B1 = 1G.[/QUOTE]

Two more xyyx candidates, last worked by Ryan.
