Hi,

I tried GMP-ECM project (the branch that is currently under active development for GPU devices) on a GPU cluster and got good results.
I want to replace ecm part of sieving step in CADO-NFS with GMP-ECM(that support GPU), but I have the following questions:

- Basically, it's a good idea or not?
- Is the GMP-ECM faster than ecm part of CADO-NFS? and if so, why the developers don't do this replacement,yet?
In addition, if all things is OK and it's a good idea, it would be pleasure if you give me some tips and points before doing that.

Thanks in advance,
Hamid
