Título:  Grid Metascheduling Using Network Information: A Proof-of-Concept Implementation
Detalle: The aggregation of geographically distributed resources in the context of a particular application has been made possible thanks to the deployment of Grid technologies. As Grids are extremely distributed systems, requirements on the communication network should also be taken into account when performing usual tasks such as scheduling, migrating or monitoring of jobs. Note that users, services, and data need to communicate with each other over networks, thus the network should be used in an efficient and fault-tolerant way. However, most of the existing efforts to provide QoS in Grids do not take into account network issues, and focus instead on processor workload and disk access. The authors have previously proposed a framework for providing network-aware grid metascheduling. The usefulness of this approach was shown by means of simulation. In this work, a proof-of-concept implementation of a metascheduler, developed as an extension to the GridWay metascheduler, is presented and evaluated. This extension harnesses network information to perform job scheduling tasks. Results show that the response time perceived by Grid users is reduced when data on network performance are used when scheduling jobs.
