MPQC is the Massively Parallel Quantum Chemistry Program.
It computes properties of atoms and molecules from first
principles using the time independent Schroedinger equation.
It runs on a wide range of architectures ranging from single
many-core computers to massively parallel computers. Its design
is object oriented, using the C++ programming language.
Capabilities
* Closed shell, unrestricted and general restricted open shell
Hartree-Fock energies and gradients
* Closed shell, unrestricted and general restricted open shell
density functional theory energies and gradients
* Second order open shell perturbation theory (OPT2[2]) and
Z-averaged perturbation theory (ZAPT2) energies.
* Second order closed shell Moller-Plesset perturbation
theory energies and gradients.
* Second order Moller-Plesset perturbation theory
including an R12/F12 correlation factor. Energies of closed-
and open-shell systems are supported.
* Explicitly-correlated R12/F12 coupled-cluster methods via
interface to Psi3 code and via native (experimental)
implementation.
* Explicitly-correlated multireference methods (MRCI, CASPT2)
via interfaces to GAMESS and MOLCAS codes.
* Robust internal coordinate geometry optimizer that efficiently
optimizes molecules with many degrees of freedom. Nearly
arbitrary internal coordinate constraints can be handled.
