Discussion related to cado-nfs

[Andrew Johnston <ajohnston9@fordham.edu>]

Hello,

I'm looking to factor some rather large numbers with CADO-NFS but could not find sufficient documentation regarding staged execution and MPI capabilities.

I'd like to run different parts of GNFS on different computers, and from what I could find CADO saves its progress (e.g. the polynomial, relations, etc.) and I should be able to move these files to different computers and rerun. Where can I find these files during execution? Further, how can I instruct CADO only to do a specific stage (e.g. only do polynomial selection)?

Further, I've read that CADO supports MPI when run from a perl script, however I could not determine which script I would need to run to utilize MPI. How do I enable this functionality? 

I apologize if I'm asking questions that can be answered in the documentation, but I could not find any resources on the subjects.

Best Regards,

Andrew H. Johnston
