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...

Bur-
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...

Uh-oh! :grin:
In my view of the factoring world, Cunninghams (even extensions) deserve some prority. So, while I bemoan the lack of efficiency caused by C195 on 15e, I understand why it happens.

That poly score matches the record for a deg 6 C217. Yuck!
I'll do a test-sieve with CADO, using 34LP on r side and 35 on a side. If I'm keeping my CADO translation straight, that's lpb0 = 34 and...

I use 120 for all but the smallest jobs (and I don't post-process the small jobs on e-small or 14 anymore). I'm not convinced 124 or 130 results in a faster-to-solve matrix anyway, and if I get a...

Looks correct to me, Ryan.
mfb1 = 101 appears marginally faster than 100, and while my 50kQ test showed the same yield it should also yield a tiny bit better. It shouldn't matter much, but 101...

The commentary from the CADO team was that as this is near the lowest deg 6 size, the alg norm is much larger than rational norm.
mfb0 = 66 is around 5% faster than mfb0 = 67. Yield is within 1%,...
