<div dir="ltr">Dear QE developers and users,<div><br></div><div>I have asked the authorities to install QE 5.4.0 on university cluster (operating system: CentOS) and now, after installation, something is wrong with the parallel executions.</div><div>I perform pwscf run and in its output file, every step is repeated equal to the number of cpu cores (N). It is similar to performing N serial runs altogether, each on a single core (please see attached output file).</div><div>I had this problem on my personal cluster (operating system: Ubuntu 16.04 LTS) with QE 5.4.0 and QE 6.0 (not with QE 5.1 that I installed using sudo apt-get install ... ). I am really confused right now, since I have no idea whether it is related to QE or mpich2. Can you please recommend me on how to solve this issue? Is there any specific setting in ./configure step?</div><div><br></div><div>Thanks for your kind response in advance.</div><div><br></div><div><br></div><div>Bests,</div><div>Afshin</div><div><br></div><div><br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div style="font-family:arial;font-size:small"><font size="1">With Best Regards</font></div><div style="font-family:arial;font-size:small"><font size="1">Afshin Arjhangemehr</font></div><div style="font-family:arial;font-size:small"><font size="1">PhD student in Radiation Application</font></div><div style="font-family:arial;font-size:small"><font size="1">Shahid Beheshti University G.C, Tehran, IRAN</font></div><div style="font-family:arial;font-size:small"><font size="1">(+98) 912 439 20 64</font></div></div></div>
