<p>Dear all,</p>
<p>I want to run my scf calculations on 4 processors. Can anyone tell me what the appropriate prompt (command) is?
<br>
</p>
<p>I myself use:</p>
<p><span> </span><span> </span><b>mpiexec -n 4 pw.x <input > output <br>
</b></p>
<p>But it takes forever and does not stop (it looks as if it's being idle).</p>
<p><br>
</p>
<p>Thank you in advance. <br>
