BookSim is a cycle-accurate interconnection network simulator. Originally developed for and introduced with the Principles and Practices of Interconnection Networks book, its functionality has since been continuously extended. The current major release, BookSim 2.0, supports a wide range of topologies such as mesh, torus and flattened butterfly networks, provides diverse routing algorithms and includes numerous options for customizing the network's router microarchitecture.
