Fair, responsive scheduling of engineering workflows on computing grids
This thesis considers scheduling in the context of a grid computing system used in engineering design. Users desire responsiveness and fairness in the treatment of the workflows they submit. Submissions outstrip the available computing capacity during the work day, and the queue is only caught up on overnight and at weekends. The execution times observed span a wide range of 100 to 107 core-min...
متن کاملJob Scheduling for Computational Grids
Grid computing is a method to execute computational jobs requiring a significant amount of computing resources and/or large sets of data. Contrary to large heterogeneous distributed systems, a Computational Grid has many independent resource providers with different access policies. In addition to the size of such a Grid, the diversity of those policies leads to a very complex allocation task t...
متن کاملA probabilistic scheduling heuristic for computational grids
1 A Probabilistic Scheduling Heuristic for Computational Grids Youcef Derbal School of Information Technology Management Ryerson University 350 Victoria Street, Toronto, ON, Canada M5B 2K3 Tel: 1(416) 979-5000 x7918 E-mail: [email protected] Abstract Computational grids are large scale distributed networks of peer clusters of computing resources bounded by a decentralized management framework ...
متن کاملSemantic Support for Meta-Scheduling in Grids
Co-ordinated usage of resources in a Grid environment is a challenging task impeded by the nature of resource usage and provision: Resources reside in different geographic locations, are managed by different organisations, and are by no means accessible via standardised interfaces, protocols or commands. These prerequisites have to be taken into account in order to provide solutions in the area...
متن کاملMulti-objective and Scalable Heuristic Algorithm for Workflow Task Scheduling in Utility Grids
To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...
