A Framework for Scheduling Image Processing Applications in MedioGRID

Abstract

This paper presents a scheduling framework that is configured for, and used in MedioGRID, a system for real-time processing of satellite images, operating in a grid environment. Our work addresses the problem of scheduling various computationally intensive and data intensive applications that are required for extracting information from satellite images. The proposed solution allows mapping of image processing applications onto available MedioGRID resources. The scheduling is done at the level of groups of concurrent applications. It demonstrates a very good behavior for scheduling and executing groups of applications, while also achieving a near-optimal utilization of the MedioGRID resources
