# 1. go to the directory, where you want to build QE, e.g. $PC2PFS/YOUR_PROJECT/QE
#
cd $PC2PFS/YOUR_PROJECT/QE
#
# 2. load the modules for building QE
# - Intel toolchain (compilers, MPI and math libraries etc)
# - CMake (cmake)
# - libxc (addon to QE)

Example of SLURM Jobscript for the AUSURF112 Benchmark
The AUSURF112 benchmark for QuantumESPRESSO is performed on 2 compute nodes of Noctua using hybrid MPI-OpenMP for the purpose of test. The input files can be obtained from this GitHub Repository.
The following SLURM jobscript downloads the input files and then performs the benchmark. The parallelization is described in the comments of this jobscript. Please replace YOUR_PROJECT with the name of your project on Noctua.
