Performance Evaluation of a Highly Concurrent Computer by Deterministic Simulation.
Abstract
Simulation is presented as a practical technique for performance evaluation of alternative configurations of a complex, highly concurrent computer system. A technique is described for constructing a detailed, deterministic model of the system. In the model, a control stream replaces the instruction and data streams of the real system. Simulation of the system model yields the timing and resource usage statistics needed for performance evaluation, without the necessity of performing the actual system computation. As an example, the implementation of a simulator of a model of the CPU-memory subsystem of the IBM 360/91 is described. The results of evaluating some alternative system designs are discussed. It appears that many of the sophisticated architectural features of the IBM 360/91 CPU would be of little value if high-speed (cache) memory is used, as in the 360/195. (Author)
