VASP

The Vienna Ab initio Simulation Package is an atomic-scale materials modelling program, (electronic structure calculations, from first principles). It is available through both the Niagara and Alliance (formerly Compute Canada) software stacks.

Licensing

If you wish to use the pre-built CC VASP binaries on Niagara, you must first write to the Alliance (formerly Compute Canada) support requesting access to VASP with the following information:

• Include license holder (your PI) information:
  1. Name
  2. Email address
  3. Department and institution (university).
• Include license information:
  1. Indicate the version of VASP license (VASP version 4 or version 5).
  2. The license number.

If you are licensed for version 5 you may also use version 4, but a version 4 license does not permit you to use version 5.

Running using the Niagara installation

Because VASP is commercial software it is hidden in the Niagara software stack by default. To see which modules are available, perform the following steps from a Niagara login node.

module use /scinet/niagara/software/commercial/modules
module spider vasp

Membership in this group is administered by the Alliance (formerly Compute Canada). See the licensing section above.

VASP uses four input files: INCAR, KPOINTS, POSCAR, POTCAR. It is best to prepare VASP input files in a separate directory for each job.
