hello Linh&paolo<br>Thanks for your reply. I am running pw.x parallely (16 cpu slot) on supercomputer but nor pp.x. I run pp.x on my desktop.<br>I did not put wf_collect=.true.<br>Below is one of my input files. <br><br>

</div>Are you running parallelly on supercomputer for both pw.x and pp.x?<br>
Have you put wf_collect = .true. yet ?<br>
<br>
It would be more clear if you attached you input files.<br>
<br>
Best regards,<br>
