Hi! Thanks a lot for the suggestions. I tried *manypw.x* just with 2 input files to see if it works. Basically, my directory consists of (drive links of text files provided)
1. Input 1 -- espresso_0.in <https://drive.google.com/file/d/1onemct-Wmm-f696KqjVU-IAbnkCXLULV/view?usp=sharing> 2. Input 2 -- espresso_1.in <https://drive.google.com/file/d/1XYmpl7awLmZbBaFH--DYvcUq5wZW92AZ/view?usp=sharing> 3. Slurm job script -- script <https://drive.google.com/file/d/1yB2GhGOrueWO13G8aIGC8o_EK8j9iEEa/view?usp=sharing> *(1 node, 8 tasks per node, 4 cpus per task, QE version 7.0)* The command I run (on Compute Canada) is the following srun --cpus-per-task=$SLURM_CPUS_PER_TASK manypw.x -ni 2 -i espresso When I submit the job, Input 2 starts and it immediately stops with the error message as described below, and Input 1 never starts. -------------------------------------------------------------------------------------------------------------- Program PWSCF v.7.0 starts on 2Jul2023 at 13:13:48 This program is part of the open-source Quantum ESPRESSO suite for quantum simulation of materials; please cite "P.

The output file is espresso_1.out <https://drive.google.com/file/d/1u43HULHS6VWddnsIhqzhpkTlaCiQIJGD/view?usp=sharing>. My understanding is that it starts for one of the inputs but when it parallely tries to start the other input, it is trying to access something that it does not have permissions. I'm not sure if this is a common error, but I was not able to see a solution for this anywhere. What could be the best way to resolve this? Please let me know if any further information is required from my side. Actually I have faced similar issues while using just pw.x and having a 'for loop' over multiple input crystals, so I thought I should find the root cause of such errors.
