I think you should try "your way" on a (well, many) small number that isn't a perfect number before you go extrapolating it to 100k-digit numbers.
Your way provides an answer. It's not the right...

I suggest you make a short project out of n=1 to n=400k to find small primes, and then decide how large an 'n' you want to set up a sieve for.

For the small primes, srsieve or newpgen to create...

I'm not sure what your experience level is with NFS matrices, but an msieve matrix roughly 26M in size fits on a 16GB machine, and something in the 45-to-50M range fits on 32GB. I haven't run a...

Behind the curve to do what?
You can solve a rather large NFS matrix with 64GB; a problem that doesn't fit would also need multiple months to solve on any sub-$5000 CPU setup.

What settings & parameters did you use? How many relations did you collect (for the first matrix, or also the final number)?

I think on small inputs the difference in LA time isn't enough to be worth much programming effort, since it's more complicated to use a hybrid versus cado-as-black-box-factorer. I don't bother to...

I'm game to do another hybrid CADO/15e-queue job with SNFS; we've done GNFS197 and GNFS198 somewhat profitably, and trying an iffy SNFS job seems fine.
