140M wasn't sufficient, but after two additional sievings the matrix was build with:


143466178 relations with 105330573 unique (73.4%)


Again the high number of uniques. Maybe the optimized...

I was wondering why it didn't update the reservation status, but since other < 10000 number actually did show reservation by someone I assumed it wasn't reserved.

Ok, I found another C159 from an aliquot sequence. I'm finishing ECM on it and then go with the 0.02 and 140M.

Btw, is there anything else to be done on the c159 or c164, such as target_density?...

It took 125 hours for the 160M relations. That's 2800 s / 1M rels or roughly 45 minutes. So yes, nearly 4 hours for 5 M rels.

It's getting funny. Cado failed at square root as expected. And msieve then decided it's too few relations to build a matrix and requested 1,000,000 more. For good measure I now have cado sieve 2M...

I'd still like to see this run with the alternative parameters. Or with alternative poly.

The relations are 3.8 GB in gzip'ed form. If you're interested in them, I could upload them somewhere.

On my system yafu won't even quit when switching to new B1/B2 values, i.e. when it reached the NFS stage. Maybe it'd be possible to catch the Ctrl-C and exit when yafu switches to the next B1 value?...

In that regard, I think at some point both cado and msieve go through several filtering iterations in which the excess...
