I’ll be happy to test sieve from Q=100 until we get ~650M relations, and then queue it in 15e. Just to confirm, we are using the poly in post 374...

Sorry, no bandwidth. Don’t wait for me. I’ll enqueue the eventual winning poly once a breakpoint for Q between CADO and 15e is determined.

Keep in mind the record GNFS score is based on degree 5 (for a c174) but your SNFS is a degree 6. They don’t directly compare unfortunately.

I’m still working on my range but I’m playing around a bit in a vain attempt to tune/optimize CADO poly searching a c204. Learning something if nothing else, but collecting data as I go.

So far...

Thank you for summarizing the issue so well. I’m varying ropteffort and nrkeep with the c204 poly search just to get a feel for the resulting poly score and runtime.

I will attempt 6e7 to 7e7 with P = 4M. May also attempt P values of 8M and 14M if my hardware can handle that search space in a reasonable time.

C191

No worries Ed - I am using msieve-GPU and there’s no real chance of overlap between the two of us.

You’ve already beaten the best poly for a C192, so finding anything better going forward is gravy.
