Overview
Quantum ESPRESSO (QE) 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.

Task and submission
Profile the given input
Use any of the remote clusters to run an MPI profile (such as IPM profile or any other profiler) over 4 nodes, full PPN to profile the given input.Submit the profile as PDF to the team's folder.
Add to your presentation the 3 main MPI calls that are being used plus the MPI time being used.
Run the QE with the given input on both PSC bridges-2 and FAU Fritz CPU clusters, and submit the results to the teams folder.
Visualize the input on any of the clusters creating a figure or video out of the input file, using any method for the visualization. In case the team has a twitter account, tag the figure/video with the team name or university name and publish on Twitter with the following tags: #ISC23 #ISC23_SCC @QuantumESPRESSO
Bonus task - run QE on the Alex cluster using A100 GPU partition. Use only 4 GPUs for the run. Submit the results to the team's folder.
Submission and Presentation:
- Submit all the build scripts, and slurm scripts used to the team’s folder.
- Prepare slides for the team’s interview based on your work for this application.
