Simulation Modelling of Parallel Systems in the Edpepps Project
نویسنده
چکیده
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 a re-connguration of the platform such as the hardware layer. The model description and the validation experiments which have been conducted to assess the correctness and the accuracy of the model are presented.

Reliability Modelling of the Redundancy Allocation Problem in the Series-parallel Systems and Determining the System Optimal Parameters
Considering the increasingly high attention to quality, promoting the reliability of products during designing process has gained significant importance. In this study, we consider one of the current models of the reliability science and propose a non-linear programming model for redundancy allocation in the series-parallel systems according to the redundancy strategy and considering the assump...
متن کاملPrototype - Oriented Development of High - performance Systems 1
In this paper, we discuss the problem of developing performance-oriented software and the need for methodologies. We then present the EDPEPPS (Environment for Design and Performance Evaluation of Portable Parallel Software) approach to the problem of designing and evaluating high-performance (parallel) applications. The EDPEPPS toolset is based on a rapid prototyping philosophy, where the desig...
متن کامل3-RPS Parallel Manipulator Dynamical Modelling and Control Based on SMC and FL Methods
In this paper, a dynamical model-based SMC (Sliding Mode Control) is proposed fortrajectory tracking of a 3-RPS (Revolute, Prismatic, Spherical) parallel manipulator. With ignoring smallinertial effects of all legs and joints compared with those of the end-effector of 3-RPS, the dynamical model ofthe manipulator is developed based on Lagrange method. By removing the unknown Lagrange multipliers...

The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...
متن کاملAn Optimization via Simulation approach for the preemptive and non-preemptive multi-mode resource-constrained project scheduling problems
In this paper a novel modelling and solving method has been developed to address the so-called resource constrained project scheduling problem (RCPSP) where project tasks have multiple modes and also the preemption of activities are allowed. To solve this NP-hard problem, a new general optimization via simulation (OvS) approach has been developed which is the main contribution of the current re...
