title: Running Jenkins job simultaneously on all nodes
body: <p><strong>TLDR</strong>: I want to be able to run job simultaneously on multiple nodes in Jenkins pipeline. [ for example - build application x on nodes dev, test &amp; staging nodes based on aws ]</p>
  <p>I have a large group of nodes with the same label.  I would like to be able to run a job in Jenkins that executes on <strong>all</strong> of the nodes with the same label as well as doing so simultaneously.</p>
  <p>I saw a suggestion to use the matrix configuration option in Jenkins, but I can only think of one axis (the label group).  When I try and run the job, it seems like it only executes once instead of 300 times (1 for each of the nodes in that label group).</p>
  <p>What should my other axis be?  Or...is there some plugin to do this?  I had tried the NodeLabel Parameter Plugin, and choosing &quot;run on all available online nodes&quot;, but it does not seem to run the jobs simultaneously.</p>
