We briefly describe the performance and accuracy of the Marseille GRAPE-3 systems. We first give the description of the configurations. We then outline the modifications necessary to optimize the tree code for use on a GRAPE system, and discuss performance and accuracy issues. We summarize the results of several science projects executed with our hardware and software.
