<p>Actually, I was running it with two processors on one node but after trying it with one processor it worked. So thanks again for all your help.</p>
<p>In any case, I was just doing this example to get familiar with the procedure and I am planning to use it for my own research. In that case the simulation will be more complicated involving many atoms. How would I know how many processors to use?</p>
<p>Is there a general rule of thumb that I can use to help guide me for the future?</p>

Quick question<br>
<br>
Is the Pseudo Potential the one suggested in the test input file? I see you are usin a pz one...i don't know but could you double check that??<br>
