title: cpu usage per process?
body: <p>How can I grab the percentage of cpu usage on a per process basis? So, for example, I'd like to run my program <code>prog</code> and get the cpu usage it incurred in, for example:</p>
  
  <pre><code>  prog name cpu0 cpu1 cpu2 cpu3  total
    prog        15   20   45   47   127%
  </code></pre>
  
  <p>Is there any tool for this?
  Thanks.</p>
