This paper presents a performance comparison of real-time system architectures. A discrete event-driven, task-based simulator is developed for evaluating the performance of parallel and distributed real-time systems. Real-time system components such as processor, network architectures, and scheduling policy are included in the simulator. simulation results show that priority-based communication and scheduling are more suitable for real-time systems than FIFO-based. The strategy of having a dedicated processor, which produces no effect on task execution by scheduling and packet/interrupt handling, is proven to enhance schedulability and predictability. This paper suggests a method for finding an appropriate real-time architecture for users having real-time requirements through the performance prediction of real-time systems.

In this paper, we present two new methods to simulate Petri Nets: a data parallelsimulation and a distributedsimulation. Both simulations use an equational representation of the net in the so called (min,+) algebra. The data parallelsimulation is based on the use of matrix representation of these equations, and the distributedsimulation on the decomposition of a Petri net into marked graph components.< >

The implementation of a distributed digital logic simulation algorithm on a network of workstations is presented. The simulation of digital circuits is done using a demand driven approach. The simulation is performed on a network of workstations using the parallel Virtual Machine (PVM) software. The use of the PVM as a platform for parallel and distributed applications is assessed in the light of the test results. The feasibility of running parallel logical simulation algorithms on such platform is considered.< >

A new partitioning method for synchronous PDES simulations is proposed. The method exploits characteristics of both the simulation method and of the application domain to arrive at efficient partitionings. A performance study shows that the method outperforms existing partitioning methods in terms of four different performance metrics.< >
