I will try to explain myself better.
I am working with power sums: sum 1/a^k, (k positive integer) where sum is
over certain large subset of
F_q(t) (F_q finite field of q elements). Since those calculations take a
lot of time (sometimes days or even weeks),
i was wondering if there is a way

That is completely false. Robert Miller implemented from scratch a
number of graph-theory
algorithms independently of the code in nauty.
I do
The license of nauty is not gpl compatible, so we can't distribute it with
Sage. There is an optional package that you can try if you want.

As far as I know both sage and magma utilize Brendan McKay's program nauty in
order to check whether two given graphs (directed or undirected) are
isomorphic. As is demonstrated by the following example, sage and magma greatly
differ in the efficiency in which this program is utilized.

Hi everybody,
I am using sagemath in server with several processors/cores, but its not
using
all the CPU resources. Most of the CPU are sitting idle.
Is it possible to build sage in such a way that all the cpu/cores?
Sage version: 'Sage Version 6.0, Release Date: 2013-12-17'

I imported the VM with the default settings. No added cores or anything.
Does it make a difference it my laptop is quad core?

You should define some order for matrices. Then you only need to compare
about log N (where N=number of matrices already in list) matrices
Your VM boot sector and grub modules don't match. Did you add extra drives
to your VM, are you sharing a bootable USB stick or floppy/cd/dvd drive?
Try importing the VM again without making any manual changes from the
defaults.

The easiest way is probably to store your matrices in a some sort of
"normal form": permute the rows and columns so that one of the smallest
entries in your matrix is in the (1,1) position and then permute rows 2,3,
... so that the entries in column one are weakly increasing from top to
bottom.
