Usage
Set-up
You can configure your environment for the usage of Quantum ESPRESSO by running the following command:
module load espresso
For QE 6.2.1 and previous versions on Owens, you need to load au2016 by module load modules/au2016 before you load espresso.
In the case of multiple compiled versions load the appropriate compiler first, e.g., on Owens to select the most recently compiled QE 6.1 version use the following commands:
module load intel/17.0.2 module load espresso/6.1
