I changed the ppn down to 1 and restart the last part. It's successful and finished just in a few seconds. Thank you very much!

Try to relaunch it on just one processor, usually it is very fast and it does not require parallelization.

Dear all,

I'm using QE to plot the layer-averaged potential for hematite (Fe2O3) surface slabs. I did scf (pw.x) first, then got the potential (pp.x), and finally tried to make layer-averaged potential (average.x) along surface normal. The first 2 steps were successful and finished in ~10 minutes. But in the last step, the output file of average.x just stopped at the beginning for several days without any new update like this:

I'm very confused about it. I don't know if I missed anything in the script for the last step. Here I added the entire run script (QEneonscript_pot_avg) of this calculation with all 3 steps below. Thank you very much for helping me with this!
