A considerable amount of research on parallel discrete event simulation has been conducted over the past few decades. However, most of this research has targeted the parallelsimulation infrastructure;focusing on data structures, algorithms, and synchronization methods for parallelsimulation kernels. Unfortunately, distributed environments often have high communication latencies that can reduce the potential performance of parallelsimulations. Effective partitioning of the concurrent simulation objects of the real world models can have a large impact on the amount of network traffic necessary in the simulation, and consequently the overall performance. This paper presents our studies on profiling the characteristics of simulationmodels and using the collected data to perform partitioning of the models for concurrent execution. Our benchmarks show that Profile Guided Partitioning can result in dramatic performance gains in the parallelsimulations. In some of the models, 5-fold improvements of the run time of the concurrently executed simulations were observed.

This paper presents a parallel processing network, a ""transputer network"", on which the dynamic real-time simulation of a single turbine generator to infinite bus power system can be realized. Based on a second-order predictor-corrector algorithm, using the features of the transputer network, a parallel simulation model of the turbine generator is proposed. The simulation program, which is written in OCCAM, has been implemented on a four-CPU transputer network. The real-time simulation results can be obtained with fifth-order generator models. Some simulation curves and discussions are given.
