title: How to limit the CPU usage of process?
body: <p>I want to limit the CPU usage of process in a GPU Server. I find some ways, "<code>nice</code>" or "<code>cpulimit</code>". But they are not exactly what I want.<br> 
  <code>cpulimit</code> allow a process to run as fast as it wants until it has exceeded a percentage after which it gets a SIGSTOP, followed by a sleep, and a SIGCONT.<br>
  But I don't want the process which exceeded a percentage to sleep. I just hope that it does not exceed a certain percentage. And keep it running in a normal way.<br></p>
  
  <p>For example, when I run <code>cpulimit -p 1111 -l 30</code>, the terminal will be<br>
  <code>[1]+  Stopped</code><br>
  This is not what I want.</p>
