PyCOOL (Cosmological Object-Oriented Lattice code) is a fast GPU accelerated program that solves the evolution of interacting scalar fields in an expanding universe with symplectic algorithms. The program has been written with the intention to hit a sweet spot of speed, accuracy and user friendliness. This is achieved by using the Python language with the¬*¬*PyCUDA (http://mathema.tician.de/software/pycuda)¬*interface to make a program that is very easy to adapt to different scalar field models. ¬*The program is publicly available (https://github.com/jtksai/PyCOOL) under GNU General Public License at. See the PyCOOL website (http://www.physics.utu.fi/tiedostot/theory/particlecosmology/pycool/) for more information.
