• Performance: "VASP: running on HPC resources".

Environment Setup

To have access to the vasp binaries, the corresponding module has to be loaded into the environment. Furthermore, the job scripts found in the tutorial tar files (job.sh, doall.sh, etc) work only if the environment variables "vasp_std, vasp_gam, vasp_ncl" are defined. Enter following commands in the terminal window after login, to setup up the environment.

module load vasp
export vasp_std="mpirun -np 8 /lustre/home/y07/vasp5/5.4.4-intel17-mpt214/bin/vasp_std"
export vasp_gam="mpirun -np 8 /lustre/home/y07/vasp5/5.4.4-intel17-mpt214/bin/vasp_gma"
export vasp_ncl="mpirun -np 8 /lustre/home/y07/vasp5/5.4.4-intel17-mpt214/bin/vasp_ncl"
