چکیده

s In grid computing, the goals of task scheduling is to achieve high system optimization performance while matching multi-dimension Quiality of Service(QoS) requirement of applications. Considering of the autonomous, heterogeneous and distributed feature of the grid system, in this paper, we propose a flexible task scheduling algorithm for grid computing after researching on the existing QoS Guide Min-min scheduling algorithm intensively, which is called distance-weighted measurement methodology (DWMM). We evaluate our algorithm within a simulated Gridsim environment. Experimental results once again proved that this flexible algorithm improve the system performance and load balancing.

Scheduling of a flexible flow shop with multiprocessor task by a hybrid approach based on genetic and imperialist competitive algorithms

This paper presents a new mathematical model for a hybrid flow shop scheduling problem with multiprocessor tasks in which sequence dependent set up times and preemption are considered. The objective is to minimize the weighted sum of makespan and maximum tardiness. Three meta-heuristic methods based on genetic algorithm (GA), imperialist competitive algorithm (ICA) and a hybrid approach of GA a...

Multidimensional Qos Oriented Task Scheduling in Grid Environments

High availability of resources is the key requirement in grids where computational and network resources are highly dynamic and unpredictable. QoS (Quality of Service) based resource management and scheduling is an important issue in such dynamic and heterogeneous grid environments. The computational resources in the grid vary from dedicated clusters to non-dedicated desktops which are connecte...
