Strategy 2 is pretty much essential when using even values of A. The performance benefit is over 10% if I remember correctly. As already discussed in this thread, it also tends to be a few percent...

Alternatively you can add niceness=19 to the command line to run tasks at low priority - though for some reason this only applies to processes run by clients rather than the server, so filtering,...

Thanks. I also tried with an April revision - from later in the same day, in fact - and it ran fine. However, it doesn't produce the same matrix, as there have been some revisions to the merge code...

In the course of investigating the bug, I found that resuming CADO - i.e. just running it again with the same command line - actually completes the factorization successfully after the crash. But of...

Yes, I'm well aware of these earlier examples - though of course the Analytical Engine was never built. I should have said "electronic computers" or something to that effect, but that's not really...

@storm5510, while we wait for the bug to be fixed, I suggest downloading an older revision of CADO and using that instead:
git clone https://gitlab.inria.fr/cado-nfs/cado-nfs.git

Workdir sets the directory where CADO will put all the files related to its current job. You should make a new one for each job and give it a helpful name, e.g. if you were factoring the 139-digit...

This is equivalent to saying that if 8p+1 is prime and of the form (2a-1)^2+64(2b-1)^2, then 2 is an 8th power mod 8p+1.
You've rediscovered an old result on when 2 is an 8th power modulo a prime....

2^lpb is the cutoff for the size of the largest primes/ideals that can appear in relations. Increasing lpb means that you find more relations, because you're allowing larger primes. But you also need...
