Without CUDA there is reliance only on the common distro provided stuff.
 
Also from the README
 
"For larger numbers, the code switches to the GMP-ECM library and runs
the P-1, P+1 and ECM algorithms, expending a user-configurable amount of
effort to do so. If these do not completely factor the input number, the
library switches to the heavy artillery. Unless told otherwise, Msieve
runs the self-initializing quadratic sieve algorithm, and if this
doesn't factor the input number then you've found a library problem. If
you know what you're doing, Msieve also contains a complete
implementation of the number field sieve, that has helped complete some
of the largest public factorization efforts known. Information specific
to the quadratic sieve implementation is contained in Readme.qs, while
the number field sieve variant is described in Readme.nfs"
 
So the user has to do some things.

"Congrats you have just finished factoring your integer and now you are
done.  Enjoy.  Remember that factoring larger numbers will take longer to
select a good polynomial, sieve, and require more time and memory for the
linear algebra stages.  Factoring a 155 digit number for example using
GNFS will take months on a quad-core PC. "

Do you want a fair assessment, or are you going to just play games?
