The CPMD code is a plane wave/pseudopotential implementation of Density Functional Theory, particularly designed for ab-initio molecular dynamics. Its first version was developed by Jurg Hutter at IBM Zurich Research Laboratory starting from the original Car-Parrinello codes. During the years many people from diverse organizations contributed to the development of the code and of its pseudopotential library:
M. Parrinello, J. Hutter, D. Marx, P. Focher, M. Tuckerman, W. Andreoni, A. Curioni, M. Boero, E. Fois, U. Roetlisberger, P. Giannozzi, T. Deutsch, A. Alavi, D. Sebastiani, A. Laio, J. VandeVondele, I. Tavernelli, A. Seitsonen, S. Billeter, V. Weber, T. Laino, I. Fedulova and others.
The current version, 4.1, is copyrighted jointly by IBM Corp and by Max Planck Institute, Stuttgart, and is distributed free of charge to non-profit organizations ( see download ). Profit organizations interested at the code should contact us . Users from non-profit organizations must apply for a license from http://cpmd.org/download/cpmd-download-1/accept-license.
CPMD runs on many different computer architectures and it is well parallelized (MPI and Mixed MPI/SMP).
