title: Running multiple Raspberry pi together
body: <p>I am part of a project to build a system and one of the requirements is that we must use the raspberry pi. </p>
  
  <p>The issue we are having is that one raspberry pi doesn't have the processing power we need to do what we want. How can I get multiple raspberry pi to work concurrently?</p>
  
  <p>edit
  We are trying to use the raspberry pi to create a matrix of infra red beams to detect when people are moving through them.</p>
