Discussion related to cado-nfs

[Emmanuel Thomé <Emmanuel.Thome@inria.fr>]

Hi,

I'm sorry, I meant to answer your emails earlier, but I was busy with
other things.

You're touching on two topics:

1 - linear algebra for DLP is _presently_ only for x86_64. This is what
is blocking you on arm, and presently you can't go further. Yes, your
analysis of the CMakeLists.txt file is correct.

For your information, if you were still struggling with linear algebra
for DLP on x86_64, it sould be good to know that the code requires that
the modulus width be explicitly covered in the compile time settings. The
setting that you can act upon is to be put in local.sh, for example like
this:

    BWC_GFP_ARITHMETIC_BACKENDS=p_4

(you can also have a list such as BWC_GFP_ARITHMETIC_BACKENDS="p_1;p_4;pz")

However, this width should be compiled in by default (see there:
https://gitlab.inria.fr/cado-nfs/cado-nfs/-/blob/master/linalg/bwc/CMakeLists.txt#L27
), so really this only matters for primes larger than 15 machine words.


2 - as Paul said, you need parameter files for your dlog size. There are
two distinct parameter files that you need.

 - The params.pNNN file. (used for all stages of the computation)
 - The pNNN.hint file. (used only for the individual log phase at the very 
end)

Starting points for both can be found in parameters/dlp/ for smaller
sizes. However, obtaining new parameters files is not an easy matter,
unfortunately. It requires a good understanding of the mechanics that
underpin the NFS algorithm in general. This is true of the params.pNNN
file, and perhaps even more obvious in the pNNN.hint. No, it is
unfortunate, be we do not have scripts to automate this.



Note that the considerations of point 1 will change soon, since I'm
currently working on changing the arithmetic layer of linear algebra.
(hard-coding will still be useful, but will become optional).

Best regards,

E.
