Thank you Prof. Giannozzi,<br>
<br>
Actually, the message "<b>image parallelization is not permitted</b>" appeared when I run pw.x ( sorry for the confusion in the last email)<br>
mpiexec -np 12 ./pw.x -nimage 2 -npool 3 <<a href="http://scf.in">scf.in</a>> scf.out<br>
<br>
So After i ran pw.x with niamge=1, I tried to run ph.x but using nimage >1 , <br>
mpiexec -np 12 ./ph.x -nimage 2 -npool 3 <<a href="http://ph.in">ph.in</a>> ph.out<br>
<br>
but I got<br>
<br>
from d_&_i : error # 1<br>
some nodes have no k-points<br><br>Thanks<br>IYAD<br><br><div class="gmail_quote">On Sat, Nov 12, 2011 at 3:35 AM, Paolo Giannozzi <span dir="ltr"><<a href="mailto:giannozz@democritos.it">giannozz@democritos.it</a>></span> wrote:<br>

</div>$ grep 'image parallelization is not permitted' ~/CVS/espresso/*/*f90<br>
(nothing found)<br>
<br>
$ grep 'image parallelization' ~/CVS/espresso/*/*f90<br>
(...)<br>
/home/giannozz/CVS/espresso/PH/phq_readin.f90: 'elph with image<br>
parallelization is not yet available',1)<br>
<br>
Is the above one the exact message you get?<br>
