Network-Aware Grid Scheduling

چکیده
Network links, as the communication media for Grid transmissions, should be considered as a parameter to decide about the convenience of using other different resources, such as CPU. This is achieved by means of a scheduling algorithm, which decides which computing resource will execute each users’ jobs. This task (the scheduling of jobs to computing resources) is done by taking into account the quality of the network links and their level of utilization. The purpose of this paper is to present an scheduling algorithm aimed at improving the network Quality of Service (QoS) in a Grid system, and demonstrate its usefulness by means of realistic Grid network simulations.

A JOINT DUTY CYCLE SCHEDULING AND ENERGY AWARE ROUTING APPROACH BASED ON EVOLUTIONARY GAME FOR WIRELESS SENSOR NETWORKS
Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...
متن کاملGame-based Models of Grid Users’ Decisions in Security Aware Scheduling
This chapter summarizes our recent research on game-theoretical models of grid users’ behavior in security aware scheduling. The main scheduling attributes, generic model of security aware management in local grid clusters and several scenarios of users’ games are presented. Four GA-based hybrid schedulers have been implemented for the approximation of the equilibrium states of exemplary simple...
متن کاملBNQM: A Bayesian Network based QoS Model for Grid service composition
The QoS attributes of Grid services play important roles in several tasks in Grid computing such as QoS-aware service composition, service negotiation, resource management, service discovery and scheduling. By considering the dynamic aspects of the Grid environments and also the uncertainty related to Grid services, in this paper, we present BNQM, a Bayesian network based probabilistic QoS Mode...
متن کاملA New Job Scheduling in Data Grid Environment Based on Data and Computational Resource Availability
Data Grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. The heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. Most existing scheduling algorithms in Grids only focus on one kind of Grid jobs which can be data...
متن کاملScheduling in Data Intensive and Network Aware (DIANA) Grid Environments
In Grids scheduling decisions are often made on the basis of jobs being either data or computation intensive: in data intensive situations jobs may be pushed to the data and in computation intensive situations data may be pulled to the jobs. This kind of scheduling, in which there is no consideration of network characteristics, can lead to performance degradation in a Grid environment and may r...
