10. Security & Licensing

• License required – Not open source; obtain from VASP Software GmbH.
• Do not redistribute vasp.5.4.4.tar.gz.
• No known malware (verified via checksum comparison with official source).
• User responsibility: comply with export controls for simulation software.

Step 1: Set up environment variables

export CXX=mpicxx

1. Extract tarball: tar -xzf vasp.5.4.4.tar.gz
2. Edit arch/ configuration file or makefile to match compiler, MPI, and library paths
3. Run make to build executables (often separate targets: vasp_std, vasp_gam, vasp_ncl)
4. Validate with provided test suite or example inputs

Basic Usage

With the binaries compiled in the bin/ folder, you are ready to run. On high-performance clusters like MIT's Satori, you’ll typically submit jobs via a scheduler like SLURM. vasp.5.4.4.tar.gz

4. Key Features (VASP 5.4.4)

• DFT+U for strongly correlated systems
• Van der Waals corrections (DFT-D2, DFT-D3, vdW-DF)
• Hybrid functionals (HSE06, PBE0)
• GW approximation for quasiparticle energies
• BSE for optical properties
• NMR chemical shifts and EPR hyperfine tensors
• MD simulations (NVT, NpT, NVE)
• Phonon calculations via finite differences

• Use the VASP manual: The VASP manual is an exhaustive resource that covers all aspects of the software. Make sure to consult it if you have any questions or issues.
• Start with a simple example: Before running a complex simulation, start with a simple example to ensure that your installation is working correctly.
• Use the VASP mailing list: The VASP mailing list is a great resource for getting help and advice from experienced users.
