      abstract     = {We investigate the performance gains from hyper-systolic
                      implementations of n2-loop problems on the massively
                      parallel computer Quadrics, exploiting its three-dimensional
                      interprocessor connectivity. For illustration we study the
                      communication aspects of an exact molecular dynamics
                      simulation of n particles with Coulomb (or gravitational)
                      interactions.We compare the interprocessor communication
                      costs of the standard-systolic and the hyper-systolic
                      approaches for various granularities. We predict gain
                      factors as large as three on the Q4 and eight on the QH4 and
                      measure actual performances on these machine configurations.
                      We conclude that it appears feasible to investigate the
                      thermodynamics of a full gravitating n-body problem with
                      O(16.000) particles using the new method on a QH4 system.},
