[Pw_forum] QE in parallel mode

[Masoud Shahrokhi]

Dear QE users,
I am trying to execute QE in parallel mode. My operation system is
CentOs 5.6. First of all I installed Openmpi-1.6.5, and then I
compiled QE 4.3.2 with ifort 11.1. When I execute QE in single mode
there is no problem but when I execute it in parallel mode I face with
this error:
 forrtl: No such file or directory
forrtl: severe (28): CLOSE error, unit 10, file "Unknown"

Also I repeated this calculation with QE 5.0.2. But this error still exists.
What should I do?
Please let me know!
Thanks in advance
