ALPS — Algorithms and Libraries for Physics Simulations

The ALPS software package aims to provide a set of well tested, robust, and standardized components for numerical simulations of condensed matter systems, including bosonic, fermionic, and spin systems. They consist of a set of components that are used in state-of-the-art high performance codes.
