An open source, GPU enabled, ab initio and density functional theory program developed by Götz lab at University of California San Diego and Merz lab at Michigan State University.
Features
- Hartree-Fock energy calculations
- Density functional theory calculations (LDA, GGA and Hybrid-GGA functionals available)
- Gradient and geometry optimization calculations (in-house and DL-FIND optimizers available)
- Mulliken charge analysis
- Exports Molden format for visualization of geometry and orbital data
- Supports QM/MM calculations with Amber22
- Fortran API to use QUICK as QM energy and force engine
- MPI parallelization for CPU platforms
- Massively parallel GPU implementation via CUDA for Nvidia GPUs
- Multi-GPU support via MPI + CUDA, also across multiple compute nodes
Limitations
- Supports energy/gradient calculations with basis functions up to d
- Supports only Cartesian basis functions (no spherical harmonics)
- Effective core potentials (ECPs) are not supported
- DFT calculations are performed exclusively using SG1 grid system
Installation
Supported platforms: Linux
