title: Jenkins with Parallel Builds
body: <p>I have a small Jenkins VM running for our shop, keep it's ever-watchful eye on about a dozen github projects.  It's currently configured with 3 executors (it's only a 4-cpu VM), and chugs along happily.</p>
  
  <p>However, 2 of these projects are very big (90-minute compile &amp; test cycle).  On workstations, we typically use "make -j6" or Ninja to speed it up, and it does so GREATLY.  I'ld like to do this on Jenkins, but I can't find a way to make a single job consume multiple executors.  </p>
  
  <p>What I'ld like is to be able to configure a number of Executors to allocate to a job, so that I don't have both of these monster jobs running at the same time, but still leave all the other smaller jobs with a single-executor each so that they can run in parallel.</p>
  
  <p>Any ideas?</p>
