#SBATCH -J <job_name>
#SBATCH --clusters=cm2_tiny
#SBATCH --partition=cm2_tiny

#SBATCH --get-user-env #SBATCH --cpus-per-task=28 #SBATCH --mail-type=end #SBATCH --mail-user=<email_address>@<domain> #SBATCH --export=NONE #SBATCH --time=24:00:00 source /etc/profile.d/ cd mydire <link to your data-set> module load wannier90 mpiexec -n 28 wannier90.x >& out.log
#or srun -n 28 wannier90.x >& out.log 

# Job Name and Files (also --job-name)
#SBATCH -J jobname
#Output and error (also --output, --error):
#SBATCH -o ./%x.%j.out

module load slurm_setup
cd $HOME/mydir
module load wannier90
mpiexec -n 160 wannier90.x >& out.log

Then submit the job script using sbatch (SLURM) or llsubmit (LoadLeveler) commands.

e.g., assume the job script name is

% sbatch


After loading the appropriate module of CP2K, the directory below contain the CP2K documentation as it comes with the source code:

 % echo $WANNIER90_DOC

Please consult the Wannier90-webpage for more documentation.


If you have any questions or problems with the installed version of Wannier90 on the different LRZ platforms, please don't hesitate to contact Dr. M. Allalen:
