We present here a performance model which simulates different versions of the hierarchical treecode on different computer architectures, including hybrid architectures, where a parallel distributed general purpose host is connected to special purpose devices that accelerate specific compute-intense tasks. We focus on the inverse square force computation task, and study the interaction of the treecode with hybrid architectures including the GRAPE boards specialised in the gravity force computation. We validate the accuracy and versatility of our model by simulating existing configurations reported in the literature, and use it to forecast the performance of other architectures, in order to assess the optimal hardware-software configuration. © 2002 Springer-Verlag Berlin Heidelberg.
