Same way Greg does- the supercomputing grids used by the CADO team for these factorizations can handle jobs such as a matrix distributed over many nodes. The paper includes a summary of the number...

This paper also exhibits the factors of RSA-250!!
Parameters were nearly the same as for RSA-240, except for increasing sieve region from A=32 to A=33 (a doubling of sieve area, equivalent to using...

Sure, but I must leave it to someone more well-versed in NFS to reply.
I believe it's the size in bits of cofactors to be fed to ECM to be split.
I believe CADO uses lambda to also control the size...

100 curves tried on the rational side (rational = side 0, as you presumed).
35 curves tried on the algebraic side; I believe the logic is that many of the cofactors won't split into 3 factors, so...

For those curious, but not curious enough to git:

Poly select used some different parameters, notably incr of 110880 (similar to tests Gimarel has run with msieve) and admax (that is, c6 max) of...

900 core-years computation time (800 sieve, 100 matrix) on 2.1ghz Xeons gold. They observe this job ran 3x faster than would be expected from an extrapolation from RSA-768, and in fact would have...
