NAMD is the result of an interdisciplinary collaboration between Prof. Kale, computer science Prof. Robert D. Skeel, and physics Prof. Klaus J. Schulten at the Theoretical and Computational Biophysics Group (TCBG) of Beckman Institute. NAMD is a parallel, object-oriented molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD is distributed free of charge and includes source code. Charm++, developed by Prof. Kale and co-workers, simplifies parallel programming and provides automatic load balancing, which was crucial to the performance of NAMD
