Discussion related to cado-nfs

[Владимир Мартьянов <vilgeforce@gmail.com>]

Hello! First of all I want to say Thankyou for your software. It starts working just out of the box, and moreover it can be started on several mchines, it's great!

I'm working in Russian antivirus company Dr.Web and for the last 4 years I'm fighting with encoders aka cryptolockers which encrypts user's files and ask for money to decrypt them. Now we're started to deal with RSA, so we need a software to factorize integers, so I have some questions about cado-nfs.

1) How cado-nfs works on multiple-core systems? For example, I'm planning to use 32-CPU-cores servers. Should I specify threads number in commandline, or cado-nfs will scale on all the cores?

2) I want to use cado-nfs in multiple-machine mode with server and slaves. What will happens if some of the slaves will be terminated without finishing it's work? Will the master reassign it's task to other slaves?

3) Is it possible to see a statistics in multi-machine mode: how many slaves do we have, how many active slaves, how many CPU-cores etc?
