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.

Running QE
Download QE benchmarks
git clone https://github.com/QEF/benchmarks.git
Practice with one of the small benchmarks called “AUSURF112”
cd benchmarks/AUSURF112 mpirun -np <NPROC> <MPI FLAGS> pw.x -inp ausurf.in
Sample output
mpirun -np 160 -x UCX_NET_DEVICES=mlx5_0:1 -x UCX_LOG_LEVEL=error pw.x -inp ausurf.in

Task and submission
Use QE 7.1 for the benchamarks:
Profile the given input (TBD - Available in oneDrive folder)
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.
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, standard output, logs and run scripts to the team’s folder.
- No need to submit the output data or source codes.
- Prepare slides for the team’s interview based on your work for this application.
