Gravity Pipe

Gravity Pipe (abbreviated GRAPE) is a project which uses hardware acceleration to perform gravitational computations. Integrated with Beowulf-style commodity computers, the GRAPE system calculates the force of gravity that a given mass, such as a star, exerts on others. The project resides at Tokyo University.

"GRAPE-3" redirects here. For the similarly named astronomy experiment, see GRAPES-3.
For the graphics processing system, see GRAPE.
Not to be confused with Gravity bong.

The GRAPE hardware acceleration component "pipes" the force computation to the general-purpose computer serving as a node in a parallelized cluster as the innermost loop of the gravitational model.

Its shortened name, GRAPE, was chosen as an intentional reference to the Apple Inc. line of computers.
