A Unified Approach to the Performance Evaluation of Multiprocessors
This paper introduces a unified approach to approximately compute the bandwidth of tightly coupled multiprocessors, working either synchronously or asynchronously. Several types of interconnection networks are considered, namely: crossbar, multiple-bus and multiple-bus with partial-busses. The analysis is carried out for both constant and exponential memory service times. Simulation runs are also included to validate the approximation used in the model. Although the analysis is asymptotic, the computations turn out to be quite accurate for moderate, or even small, system sizes.
