In this paper, a simulation model for incorporation within a performance-oriented parallel software development environment is presented. This development environment is composed of a graphical design tool, a simulation facility, and a visualisation tool. Simulation allows parallel program performance to be predicted and design alternatives to be compared. The target parallel system models a virtual machine composed of a cluster of workstations interconnected by a local area network. The simulation model architecture is modular and extensible which allows re-configuration of the platform, The model description and the validation experiments which have been conducted to assess the correctness and the accuracy of the model are also presented.
In this paper two research projects are overviewd. The first intended to explore the possibility of implementing Prolog on a typical SIMD machine, called Distributed Array Processor (DAP). The second project focusses ...

This paper describes an integrated graphical toolset for performance-oriented design of portable parallel software. The toolset consists of a graphical design tool based on the PVM communications library for building parallel algorithms, a simulation engine and a visualisation tool for animation of program execution and visualisation of platform and network performance measures and statistics. The toolset is used to model a virtual machine composed of a cluster of workstations interconnected by a local area network. The simulation model used is modular and its components are interchangeable which allows easy reconfiguration of the platform. The model is validated using experiments on the COMMS1 Benchmark from the Parkbench suite, and a standard image processing algorithm with accuracy to within 10%.
With the latest advances in the area of advanced computer architectures we are seeing already large scale machines at petascale level and we are discussing exascale computing. All these require efficient scalable algo...

For an agent-based system that aims to simulate a large number of agents under different scenarios, a proper partitioning mechanism is an essential factor to the performance of the system. However, there is still an issue on selecting/ developing an appropriate partitioning mechanism for a specific agent-based simulation system. One way is to implement distributed agent-based systems using multiple partitioning mechanisms and to compare their performance. However this is in general not feasible. In this paper, we propose a generic framework and a simple evaluation process to address the issue of selecting an appreciate partitioning mechanism by simulating the effect of the partitioning mechanism to predict its performance for an agent-based simulation system.
A formal, representation-independent form of a memetic algorithm-a genetic algorithm incorporating local search-is introduced. A generalised form of N-point crossover is defined together with representation-independen...

This paper presents a tool for the visualization and simulation of automated stowage plan generation for large containership. The stowage plan is generated automatically based on a heuristic algorithm. The allocation algorithm generates different stowage plan in three main stages which includes basic allocation, special container allocation and various stages of stability adjustments. The purpose of this study is to describe how visualization of stowage plan and simulation of allocation sequences can help in the formulation of new and better stowage allocation algorithm.
