title: Using php and MPI
body: <p>I currently have a php file which allows the user to upload a file.  Once they upload the file, it runs a program with the file using MPI. </p>
  
  <p>The problem is that the script says it cannot find the file .mpd.conf (config file that must be present in users home directory).  I'm guessing that this is because it is running as a different user than myself.</p>
  
  <p>I am using apache2 to serve this webpage, can anyone help me get this working?  I don't know too much about how PHP works.</p>
