Since the problem of scheduling independent jobs in heterogeneous computational resources is known as NP-complete, an approximation or heuristic algorithm is highly desirable. Grid is an example of the heterogeneous parallel computer system. Many researchers propose Continue reading

A Comparison among Grid Scheduling Algorithms for Independent Coarse-Grained Tasks
The most common objective function of task scheduling problems is makespan. However, on a computational grid, the 2nd optimal makespan may be much longer than the optimal makespan because the computing power of a grid varies over time. So, if the performance Continue reading
Workflow Scheduling Algorithms for Grid Computing
Workflow scheduling is one of the key issues in the management of workflow execution. Scheduling is a process that maps and manages execution of inter-dependent tasks on Continue reading
Ant Algorithm for Grid Scheduling Problem
Grid computing is a form of distributed computing that involves coordinating and sharing computing, application, data storage or network resources across dynamic and geographically dispersed Continue reading
A Task Scheduling Algorithm Based on PSO for Grid Computing
Grid computing is a high performance computing environment to solve larger scale computational demands. Grid computing contains resource management, task scheduling, security problems, information management and so on. Task scheduling is a Continue reading
A QoS Guided Scheduling Algorithm for Grid Computing
Task scheduling is an integrated component of computing. With the emergence of grid and ubiquitous computing, newer challenges have arisen in task scheduling. Unlike traditional parallel computing, grid is a shared enterprising environment where is no central control. The goal of grid task scheduling is to Continue reading
Scheduling in Grid Computing Systems
Grid computing involves employing multiple machines to solve complex computing problems. For my project I have simulated a grid computing system based on a cluster of machines located at the University of Calgary. Data was collected from this system over a period of Continue reading
