We describe the software system used for GRAPE processors, special-purpose computers for gravitational N-body simulations. In gravitational N-body simulations, almost all of the calculation time is spent to calculate the gravitational force between particles. The GRAPE hardware calculates the gravitational force between particles using hardwired pipelines with a speed in the range of 100 Mflops to 10 Gflops, depending on the model. All GRAPE hardware systems are connected to general-purpose workstations, on which the user program runs. In order to use the GRAPE hardware, a user program calls several library subroutines that actually control GRAPE. In this paper, we present an overview of the user interface of GRAPE software libraries and describe how they work. We also describe how the GRAPE system is used with sophisticated algorithms, such as the tree algorithm or the individual time step algorithm.
