Once you find the exact line where it freezes, either you easily find why, or, if there is no obvious reason, it is likely a problem of your compiler/ libraries / mpi.<br><br></div>Paolo<br><div><br></div></div><div class="gmail_extra"></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Feb 2, 2016 at 4:40 PM, joaquin peralta <span dir="ltr"><<a href="mailto:jperaltac@gmail.com" target="_blank">jperaltac@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Dear Youssef,<div><br></div><div>I did the compilation as you indicated, however my QE-run frozen with more than one CPU.

./configure --enable-parallel<br>
</strong><br>
you can save it as a bash script, an run it inside qe folder.<br>
<br>
Of course make sure that the intel parallel studio wrapper is in
your path (e.g. : source /opt/intel/bin/compilervars.sh intel64 ),
this invoke all the needed environmental variables.<br>
