title: How to set CPU load on a Red Hat Linux box?
body: <p>I have a <a href="http://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux" rel="noreferrer">RHEL</a> box that I need to put under a moderate and variable amount of CPU load (50%-75%).</p>
  
  <p>What is the best way to go about this? Is there a program that can do this that I am not aware of? I am happy to write some C code to make this happen, I just don't know what system calls will help.</p>
