| IBM Cyclops64 (C64) is a petaflop supercomputer built on multi-core System-On-Chip (SOC) technology, which is attached to a host system through a number of Gigabit Ethernet links and provides familiar computing environment to application developers and end users.; This thesis presents a brief overview of the C64 crossbar switch and describes details about its performance simulation and analysis. The metrics for the performance analysis of the C64 crossbar switch that I am going to focus on are its latency and throughput. A C64 crossbar simulator, csim_crossbar, and a C64 chip simulator, LAST, are used to simulate the architecture and gather statistical data for the performance analysis. The performance analysis is done under certain constraints (Fixed channel width and node size as well as topology). Different parameters, such as type of workloads, traffic patterns, injection rate, packet size and arbitration algorithms, are implemented during the performance simulation.
