Yes I think that rule of thumb was associated with ggnfs. I believe this rule was more computational then mathematical in nature but it was years ago. Can’t find any old posts but I’ll dig some more....

No doubt. In the past I’ve compared the skew values as generated by msieve/CADO with the one suggested by cownoise and honestly found little difference. But that’s hardly authoritative. My point is...

Lot of high e-scoring candidates!

How critical is the skew wrt sieving efficiency for these bigger GNFS jobs? Cownoise (and presumably msieve) doesn’t use an input value for skew in the score...

This job file seems “old fashioned”, with m and the declaration that it’s a sextic. And no Y0,Y1 values. Yes I realize they can be derived from m but is this form acceptable to NFS@Home’s flavor of...

Plutie -

I am curious, what parameters did you use in finding this poly?

One other note, when I first saw this posted it had another skew per CADO but then you edited it to match cownoise. Do...

These ultra high skews associated with high e-score polys may be reducible by half (or more) with Max’s script(s). He has managed this feat several times in the past.

8-3,341

The HCN 8-3,341 is ready for GNFS. As a c193, this job definitely belongs on 16f_small but I ended up splitting the lpbr/a into a 31/32 after extensive (and intentionally naive) test sieving of 24...

I just saw this post and yes it appears to be stuck. I’ve asked Greg to take a look - it seems a typo crept into the skew (“Skew” - mea culpa), maybe this is the problem? Anyway I can’t correct it.
