Discussion related to cado-nfs

[Andrew Johnston <ajohnston9@fordham.edu>]

Hello all,

Before I begin, I'd like to thank everyone in advance for helping a beginner out.

For starters, I plan on running CADO on a cluster. I believe the cluster has a job submitter that manages the number of cores a program uses. Are there any ways to ensure CADO uses all of the allotted cores? Right now I'm running it on a computer with no restrictions and its only using ~1% of the CPU. I only have access to this cluster for a certain amount of time and I want to be sure I'm maximizing my usage.

Secondly, I was wondering if you had any resources on how GNFS determines free relations and whether a relation is 'useful'. If you had any documentation on how that is done that you could refer me to I'd be very appreciative. I tried going through the source code but I couldn't quiet understand the logic

Thanks again for all of your help.

Best,

Andrew
