// Here is an extremely simple version of work scheduling for multiple
// processors.
//
// The Problem: 
//  We have a lot of numbers that need to be math'ed. Doing this on one 
//  CPU core is slow. We have 4 CPU cores. We would thus like to use those
//  cores to do math, because it will be a little less slow (ideally
//  4 times faster actually).
//
// The Solution:

# This is how you add a Jenkins slave

# On master:

  sudo -u jenkins -H ssh-keygen

# On slave

  adduser --system --group --home=/var/lib/jenkins-slave --no-create-home --disabled-password --quiet --shell /bin/bash jenkins-slave
  install -d -o jenkins-slave -g jenkins-slave /var/lib/jenkins-slave
