VeloxChem

A science- and education-enabling software platform for quantum molecular modelling on contemporary and future HPC systems

What is VeloxChem

VeloxChem is a Python-based open-source quantum chemistry software developed for the calculation of molecular properties and simulation of a variety of spectroscopies. It features interactive program access through Jupyter notebooks as well as large-scale calculations in contemporary high-performance computing (HPC) environments. With a layered Python/C++ language design, it achieves excellent parallel scaling for spectrum simulations of complex molecular systems.

VeloxChem development partners

VeloxChem is primarily developed by research software engineers at PDC and researchers at KTH Royal Institute of Technology, with contributions from researchers at other universities.

Current developments

Recently, the VeloxChem team at KTH and PDC implemented the evaluation of electron repulsion integrals (ERIs) and Fock matrix formation on GPUs to push the limit of the sizes of the systems that can be routinely studied with VeloxChem. The performance of the Fock matrix formation and ERI evaluation in VeloxChem was tested by running Hartree-Fock calculations for a series of water clusters on Dardel. For more information about this, see VeloxChem: Electron Repulsion Integrals and Fock Matrix Formation on GPUs .
