Surface transportation systems continue to be plagued by concerns regarding safety, excessive delays, and pollution. These problems will only become progressively worse in the future, particularly in developing nations as they modernize and become more mobile. The widespread deployment of smart vehicles that include unprecedented computation, wireless communication, and sensing capabilities wil...

this article describes “SPREAD”, a simulation tool kit and its use in building “Virtual Robots”, a simulation of multiple mobile robot vehicles used in the teaching of Computer Science at university level. A novel aspect of the simulator is the use of PVM [1] to achieve high performance at low cost by using spare CPU cycles on large numbers of networked workstations.

The information technology (IT) world has changed fundamentally and drastically from running software applications on a single computer with a single CPU to now running software as services in distributed and parallel computing environment. Power system operation has been also shifted from being solely based on off-line planning study to more and more real-time market-driven. Facing these chall...

This paper outlines the implementation of a distributed billiard ball simulation in C++ using the MPI message passing interface. The implementation is heavily modelled after the discussions and algorithms found in [Lubachevsky 1991] and [MacKenzie and Tropper 1996]. [Lubachevsky 1991] outlines an efficient but non-distributed simple rigid disc simulator that assumes no friction, spin, et cetera...

The performance of logical process based distributed simulation (DS) protocols like Time Warp and Chandy/Misra/Bryant is influenced by a variety of factors such as the event structure underlying the simulation model, the partitioning into submodels, the performance characteristics of the execution platform, the implementation of the simulation engine and optimizations related to the protocols. ...

We propose a method for emulating the behavior of your favorite MIMD computer on a network of workstations, so that programs written for the MIMD target can run on the distributed emulated version with just a recompilation. This is achieved by executing the computational parts as in the native run, with the message passing being simulated. The hardware of the target machine is simulated so that...

Decentralised, event-driven distributed simulation is particularly suitable for modelling systems with inherent asynchronous parallelism, such as agentbased systems. However the efficient simulation of multi-agent systems presents particular challenges which are not addressed by standard parallel discrete event simulation (PDES) models and techniques. PDES approaches based on the logical proces...

We propose a new practical technique for the distributed execution-driven simulation of parallel computers. Our simulation methodology allows complete virtualization of the design at all levels and achieves good performance by preserving and exploiting the parallelism of the parallel program being simulated. With our technique it is possible to decouple the simulation of the execution of a para...

Queuing systems are an important building block for performance evaluation in various application areas, due to their powerful, yet simple nature. Although it is often possible to perform an analytical evaluation of a queuing model, simulation of queuing systems remains an important technique in the context of performance evaluation. In order to speed up queuing simulation executions, parallel ...

Traditional discrete-event simulations employ an inherently sequential algorithm and are run on a single computer. However, the demands of many real-world problems exceed the capabilities of sequential simulation systems. Often the capacity of a computer’s primary memory limits the size of the models that can be handled, and in some cases parallel execution on multiple processors could signific...
