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
To start, we at SciNet don't have a site license, and we are not able to provide VASP on Niagara through CVMFS (CCEnv). If you want to run VASP on SciNet systems you or your PI must already have your own license from your UofT department or institution. This way we can make arrangements to honor that license on our systems.
To use the pre-built 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:
- Name
- Email address
- Department and institution (university).
- Include license information:
- Indicate the version of VASP license (VASP version 4 or version 5).
- 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 5.4.4
Example submission script for a job running on 2 nodes, with max walltime of 11 hours:
#!/bin/bash #SBATCH --nodes=2 #SBATCH --ntasks=80 #SBATCH --time=11:00:00 #SBATCH --job-name test module load NiaEnv/2018a module use /scinet/niagara/software/commercial/modules module load intel/2018.2 intelmpi/2018.2 module load vasp/5.4.4 mpirun vasp_std
VASP uses four input files: INCAR, KPOINTS, POSCAR, POTCAR. It is best to prepare VASP input files in a separate directory for each job.
