title: Running same python from two different cores
body: <p>Is there a problem in running a python script from two different processes on separate cores on a cluster.
   The script resides in a global folder (accesable by both processes):</p>
  
  <pre><code>/cluster/A.py
  </code></pre>
  
  <p>I am concerned about the pycache and other stuff python writes...?
  Do both cores have problems in generating the same pycache in folder /cluster/
  Can I safely do this or are there some issues?</p>
