Given the licensing conditions of VASP, users of VASP on LUMI need to provide their own license, but can use the provided EasyConfig files for the installation. See the user documentation that we provide.
VASP (Vienna Ab Initio Simulation Package) is a popular software package for "atomic scale materials modelling from first principles". In general, it runs well on LUMI-C.
There is currently no version of VASP that can use the AMD GPUs in the GPU Early Access Platform or LUMI-G.
We provide automatic installation scripts for several versions of VASP. In general, the installation procedure is described on the EasyBuild page. The step by step procedure to install VASP 6.3.2 is:
- Download the VASP source code "vasp.6.3.2.tgz" from the VASP portal.
- Upload the file somewhere to your home directory on LUMI.
- Load the LUMI software environment:
module load LUMI/22.12.
- Select the LUMI-C partition:
module load partition/C.
- Load the EasyBuild module:
module load EasyBuild-user.
Then, you can run the install command:
The installation process is quite slow. It will take about 20 minutes, but afterwards, you will have a module called "VASP/6.3.2-cpeGNU-22.12" installed in your home directory. Load the module to use it
The usual VASP binaries,
vasp_gam etc. will now be in your
PATH. Launch VASP via the Slurm scheduler, e.g.
vasp_std. Please note that you must do
module load LUMI/22.12 partition/C to
see the VASP module in the module system. The same applies to the Slurm batch
scripts which you send to the compute nodes.
You can see other versions of VASP that can be automatically installed in the same way by running the EasyBuild command
or by checking the list further down this page or by checking the LUMI-EasyBuild-contrib repository on GitHub directly.
We build the VASP executables with bindings to several external libraries activated: currently HDF5, Wannier90, DFTD4, and Libxc. There are also some patches made to the reading of input files to less the load on the parallel file system.
Example batch scripts
A typical VASP batch job using 4 compute nodes and MPI only:
##!/bin/bash ##SBATCH -J GaAs512 ##SBATCH -N 4 ##SBATCH --partition=small ##SBATCH -t 00:30:00 ##SBATCH --mem=200G ##SBATCH --exclusive --no-requeue ##SBATCH -A project_XYZ ##SBATCH --ntasks-per-node=128 ##SBATCH -c 1 export OMP_NUM_THREADS=1 module load LUMI/22.12 partition/C module load VASP/6.3.2-cpeGNU-22.12 srun vasp_std
A typical VASP batch job with MPI and 8 OpenMP threads per rank:
##!/bin/bash ##SBATCH -J GaAs512 ##SBATCH -N 4 ##SBATCH --partition=small ##SBATCH -t 00:30:00 ##SBATCH --mem=200G ##SBATCH --exclusive --no-requeue ##SBATCH -A project_XYZ ##SBATCH --ntasks-per-node=16 ##SBATCH -c 8 export OMP_NUM_THREADS=8 export OMP_PLACES=cores export OMP_PROC_BIND=close export OMP_STACKSIZE=512m module load LUMI/22.12 partition/C module load VASP/6.3.2-cpeGNU-22.12 srun vasp_std
Due to the restrictive license conditions imposed by the VASP group, which forbids sharing of any kind of benchmark numbers with anyone (including other licensed users!), we unfortunately cannot give detailed recommendations on the best way to run VASP.
- In general, try increasing
NCOREto 16-32, and
- OpenMP works best with many threads, eg.
OMP_NUM_THREADS=8. OpenMP works particularily well with exact exchange calculations.
- It is best to run with all 128 processor cores per compute node if you can, but reducing the number of cores per compute node does not decrease performance as much as you might expect. That can be useful when you are constrained by memory and need more available memory per MPI rank. It is important to explicitly pin the MPI ranks to processor cores if you run with less than 128 cores per node.
- If possible, use k-point parallelization
KPARup to the maxium number of k-points. It is often a good choice to use 1 compute node per k-point.
- We generally recommend using VASP version 6 when possible, and not VASP 5 (even though installation scripts are provided). VASP 5 on LUMI exhibits some problems with disk I/O, jobs may appear to hang for several minutes at launch before all input files are read and the calculation begins.
User-installable modules (and EasyConfigs)
Install with the EasyBuild-user module:

VASP support in EasyBuild. Given the licensing conditions of VASP, it is difficult to maintain in the regular EasyBuild repository.
The VASP EasyConfig files for LUMI are build upon those of the CSCS repository, with Makefiles specifically for LUMI.
The EasyConfigs below are additonal easyconfigs that are not directly available on the system for installation. Users are advised to use the newer ones and these archived ones are unsupported. They are still provided as a source of information should you need this, e.g., to understand the configuration that was used for earlier work on the system.
