We implement the data decomposition algorithms towards the calculation of three-body interactions in the Stillinger-Weber potential for a system of water molecules. The performance is studied in terms of load balance and speedup from the MPI implementations of the two algorithms. We are also currently working on a performance study of the disc decomposition algorithm on graphics processing units (GPUs).
