QMC@Home
QMC@Home was a volunteer computing project for the BOINC client aimed at further developing and testing Quantum Monte Carlo (QMC) for use in quantum chemistry. It is hosted by the University of Münster with participation by the Cavendish Laboratory. QMC@Home allows volunteers from around the world to donate idle computer cycles to help calculate molecular geometry using Diffusion Monte Carlo.

Post-Hartree–Fock
In computational chemistry, post–Hartree–Fock (post–HF) methods are the set of methods developed to improve on the Hartree–Fock (HF), or self-consistent field (SCF), method. They add electron correlation which is a more accurate way of including the repulsions between electrons than in the Hartree–Fock method where repulsions are only averaged.
