EESSI¶
EESSI modules are now available on VSC systems!
The European Environment for Scientific Software Installations (EESSI, pronounced as "easy") is a collaboration between different HPC sites and industry partners, with the common goal to set up a shared repository of scientific software installations that can be used on a variety of systems, regardless of which flavor/version of Linux distribution or processor architecture is used, or whether it is a full-size HPC cluster, a cloud environment or a personal workstation, and without compromising on the performance of the software.

#!/bin/bash
#SBATCH -J test_job
#SBATCH -N 1
#SBATCH --partition zen3_0512
#SBATCH --qos zen3_0512
eessi
module load lammps #for example
srun --mpi=pmix lmp -i in.meam
