In real-time simulation, the system being simulated should display the same timing behavior as the target system. The simulation accuracy is increased as the simulation time unit is decreased. Although there are several models for such a system, the TMO (Time-triggered Message-triggered Object) model is particularly appropriate due to its natural support for real-time distributed object-oriented programming. This paper discusses the results of the implementation of a real-time airplane-landing simulator on a distributed computing environment using the TMO model.

A real-time fault-tolerant multicast protocol is necessary for obtaining high performance in operating distributed real-time computing systems. This paper shows the efficiency of the RFRM (Release-time based Fault-tolerant Real-time Multicasting) protocol, which is based on the idea of attaching the official release time to each multicast message. As a part of this, a real-time simulation based on the TMO (Time-triggered Message-triggered Object) structuring scheme is conducted in order to evaluate the proposed approach. We experiment with a real-time multicast model which does not receive ACK messages, with the purpose of reducing the message traffic on the network by employing a fault detection mechanism. simulation results promise good efficiency for the proposed real-time multicast protocol.

The main aim of the paper is to present some preliminary results of the speedup of a distributed simulator for ground water dispersion systems. A sequential version simulator calculates the concentrations during the dispersion of an aquifer. Depending on the number of nodes used in the grid for the simulation, the simulation time can be prohibitive. Thus a distributed simulator (DGWSDS) was developed, and the preliminary results of it speedup are shown here. Basically, the numerical method used in this simulator is finite differences. The distributed groundwater simulator dispersion system proposed and implemented achieved speedups up to 3, for a network of 8 PCs.
