Quantum Espresso
Quantum ESPRESSO
is an integrated suite of Open-Source computer codes for electronic-structure
calculations and materials modeling at the nanoscale.
It is based on density-functional theory, plane waves, and pseudopotentials.
Quantum ESPRESSO has evolved into a distribution of independent and inter-operable codes in the spirit of an open-source project. The Quantum ESPRESSO distribution consists of a “historical” core set of components, and a set of plug-ins that perform more advanced tasks, plus a number of third-party packages designed to be inter-operable with the core components. Researchers active in the field of electronic-structure calculations are encouraged to participate in the project by contributing their own codes or by implementing their own ideas into existing codes.

Interactive mode¶
To open an Quantum ESPRESSO in the interactive mode, please follow the following steps:
# From your local computer
$ ssh -X iris-cluster
# Reserve the node for interactive computation
$ salloc -p interactive --time=00:30:00 --ntasks 1 -c 4 --x11 # OR si --x11 [...]
# Load the module quantumespresso and needed environment
$ module purge
$ module load swenv/default-env/devel # Eventually (only relevant on 2019a software environment)
$ module load chem/QuantumESPRESSO/6.4.1-intel-2019a
$ pw.x -input example.in
