VASP at TACC
Last update: May 19, 2020

VASP logo Vienna Ab initio Simulation Package (VASP) is a computer program for atomic scale materials modelling, e.g. electronic structure calculations and quantum-mechanical molecular dynamics, from first principles.

TACC and VASP

VASP requires an individual license. TACC's HPC support license allows us to install only the compiled VASP executables and grant the access to licensed users who have accounts on our systems. We are not allowed to share source code.

If you have your own license and want to use your own compilation, you may install it in your own account. If you wish to use TACC's installed version, then TACC will have to verify your license. Submit a support ticket and include the following information: your FULL name, affiliated institution, and your TACC user name along with the license number or a scanned PDF of the license. TACC will notify you once the license is confirmed.

Installations

The latest stable release of VASP is installed on Stampede2, Lonestar 5 and Frontera systems. Note that you will be unable to load any VASP module until your license is confirmed.

As of this date, TACC has versions 5.4.4.pl2 installed. We expect VASP/6.1.0 will soon be available. Use "module" commands to explore VASP installations:

login1$ module spider vasp
login1$ module spider vasp/5.4.4.pl2

Then, either interactively or via a batch script, load the appropriate module:

login1$ module load vasp/5.4.4.pl2

Running VASP Jobs

TACC staff recently presented "VASP on Frontera and Stampede2", detailing how to build and run VASP, and troubleshoot run time issues on TACC systems. Check out the recorded webinar and accompanying slides.

Use the following job scripts for VASP jobs on Stampede2 and Frontera. To configure a script for Lonestar 5, vary the "-N" and "-n" directives.

Sample Job Script: VASP on Frontera

The script below submits a VASP job to Frontera's normal queue (CLX compute nodes), requesting 4 nodes and 224 tasks for a maximum of 4 hours. Refer to Frontera's Running Jobs section for more Slurm options.

#!/bin/bash 
#SBATCH -J vasp          
#SBATCH -o vasp.%j.out     
#SBATCH -e vasp.%j.err 
#SBATCH -n 224         
#SBATCH -N 4 
#SBATCH -p normal      
#SBATCH -t 4:00:00        
#SBATCH -A projectnumber

module load vasp/5.4.4.pl2
ibrun vasp_std > vasp_test.out

Sample Job Script: VASP on Stampede2

The script below requests 4 nodes and 256 tasks, for a maximum of four hours in Stampede2's normal queue (KNL compute nodes). See the Stampede2 User Guide: Common sbatch Options for more about job options.

#!/bin/bash 
#SBATCH -J vasp          
#SBATCH -o vasp.%j.out     
#SBATCH -e vasp.%j.err 
#SBATCH -n 256         
#SBATCH -N 4 
#SBATCH -p normal      
#SBATCH -t 4:00:00        
#SBATCH -A projectnumber
