<p>Dear QE users, <br>
</p>
<p><br>
</p>
<p>Can anyone tell me how to do scf calculations in parallel? I have done an scf calculation on one processor and now I want to do it on 2, 4, and 8 processors. One on processor it took 14 minutes to finish, however, when I run it on 2, 4, 8 it takes forever
(it really never finishes). I use the following command " <b>mpirun -np 4 pw.x -inp INPUT_FILE |tee OUTPUT_FILE
</b>". <br>
</p>
<p><br>
</p>
<p>Any help would be thoroughly appreciated. <br>
</p>
<p><br>
</p>
<p><br>
</p>
<p>Best,<br>
</p>
<p><br>
