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.
- Hartree-Fock
- Density functional theory (LDA, GGA and Hybrid-GGA functionals)
- Grimme type dispersion corrections
- Restricted closed-shell and unrestricted open-shell wavefunctions
- Gradient and geometry optimization calculations (in-house and DL-FIND optimizers available)
- Includes a wide range of popular Gaussian basis sets
- Mulliken charge analysis
- Exports Molden format for visualization of geometry and orbital data
- Supports QM/MM calculations with Amber22 and later
- Fortran API to use QUICK as QM energy and force engine
- MPI parallelization for CPU platforms
- Massively parallel GPU implementation via CUDA/HIP for Nvidia/AMD GPUs (HIP available in QUICK-23.08, currently disabled)
- Multi-GPU support via MPI + CUDA/HIP, also across multiple compute nodes
- Supports energy/gradient calculations with basis functions up to f
- GPU f function code is not highly optimized, requires large amount of RAM (may fail on consumer GPUs)
- No open shell gradients with f functions on GPUs
- Supports only Cartesian basis functions (no spherical harmonics)
- Effective core potentials (ECPs) are not supported
- DFT calculations are performed exclusively using the SG1 grid system
- No meta-GGA functionals, no range-separated hybrid functionals
- HIP (AMD GPU support) is currently disabled (available in QUICK-23.08 but not QUICK-24.03)
Supported platforms: Linux (x86 and ARM), macOS (x86 and ARM)
A list of installation and runtime issues can be found here.

Although QUICK is tested on a range of hardware with different compiler versions, we cannot guarantee that it will work flawlessly in all your applications. But we are working hard to detect and fix any issues. If you experience any compile or runtime issues, please report to us through the issues section of this repository. We appreciate any feedback and contributions to the code.
