It's hard to help you when you give such vague information. Exactly what would not work "below in readme"? What did you try, and what was the result?
"any command line references" is also really...

Excellent!
I'll start with the C141 Saturday, and then a couple of the C140s. If you and Gary could skip those specifically, just C140 and C141 will hold me over for a couple days (and hopefully...

Those binaries are all there are for the GGNFS siever software. The number 11 through 16 in the binary names indicate the "size" of the siever, in that larger sievers are used to factor larger...

When I first discovered that the stock params were not very fast, I sent new files to the CADO folks for C100 to C120. Some of them were accepted, others were deemed not a useful improvement. One...

NFS = Number Field Sieve. That's a method of factorization.
GNFS and SNFS are types of NFS jobs: General and Special. General is just that- the input number has no special form. Special means the...

I return home Saturday, I ought to be able to post a faster one Sunday for C150 and C155.
I was nearly done refining C100-C130 params when I left on this trip; C135-C155 I still have more data to...

Yep! There's lots of factoring projects out there, and many of them have a pleasant intellectual challenge to figure out how to make SNFS polynomials when such forms are possible.

Aw, thanks for the shout-out, Sean!
I can clarify a little bit about the 0.055 and 0.06 ratios for stage 1 and stage 2 norms:
Stage 1 is the part run on the GPU, and even a slow GPU produces a...

I've never noticed this- my matrices seem to depend on input size much more than LP size, until I get to 32LP. I'd be quite surprised to learn that 30 vs 31 is more than 15% larger matrix, for a...

When testing params choices on CADO, I find I need 2-3% more relations per digit for a given LP bound choice, and 70% more relations for a given input number for each increase of 1 LPB. 2% per...

If uniform density, centre of mass of a finite sphere is at the center of the sphere; or, why isn't it the same for a circle, sphere, and 3-sphere? I suppose I'm missing a subtlety when addressing a...

For gnfs jobs, qmax should be no more than 8 times qmin, otherwise the duplicate ratio gets so high as to make the lower-Q relations not worth gathering.
Maybe start this job at Q= 60M? Or is my...

With use of remdups and remsing, I'm confident that a 36/35 job could be sent to msieve with fewer than 4G relations.
We can also do a team-sieve with CADO for low Q, say 100-250M, with A=32 and...
