Molecular Dynamics (M.D.) simulation is a widely used computational te
chnique to study the properties of many-body (atom) systems. Because t
he number or particles in these simulations is large, and many time st
eps are required to cover the minimal time span on which biomolecular
processes take place, M.D. simulations or these systems are notoriousl
y CPU time consuming. For this reason, we designed and constructed a p
arallel computer suited for M.D. simulations. In this article we give
an overview of the architecture, the software and new M.D. techniques
used.
