    "abstract": "We report the results of intensive numerical calculations for four atomic\nH2+H2 energy transfer collision. A parallel computing technique based on\nLAM/MPI functions is used. In this algorithm, the data is distributed to the\nprocessors according to the value of the momentum quantum number J and its\nprojection M. Most of the work is local to each processor. The topology of the\ndata communication is a simple star. Timings are given and the scaling of the\nalgorithm is discussed. Two different recently published potential energy\nsurfaces for the H2-H2 system are applied. New results obtained for the state\nresolved excitation-deexcitation cross sections and rates valuable for\nastrophysical applications are presented. Finally, more sophisticated\nextensions of the parallel code are discussed.",
