[QE-users] QE didn't generate output files in scf calculation

[Husak Michal]

Sorry
The sintax is:
mpirun -np 4 pw.x < scf.in > scf.out
You work probably on Linux ...

On Windows you can use
pw.exe < scf.in > scf.out

MP is set defalut to 4 ... Can be controled by enviromental variable.
MPI run on Windows is a bit complex (I can send .bat Monday).

If you know nothing about Quantum Espresso I suggest to start under Windows wit BURAI user interface, before you start to do things manualy ...

I do that, but I received this error: How can I run this file??

 No executable was specified on the mpirun command line.

Aborting.

Check documentatio. The filenames are not paramsters, but IO sources ..

Hi
I am new to quantum espresso, and as the first step, I wanna calculate SCF file calculation and get output files.
I entered the following command in the terminal, but after passing up to 8 hours I didn't have any output file. Can you help me to solve this problem??
==========
entered command:
$ $ mpirun -np 2 pw.x Sample-1.pw.in<http://Sample-1.pw.in><http://Sample-1.pw.in> Sample-a.pw.out

what appeared in terminal:
