Abstract

Grid computing is moving into two ways. TheComputational Grid focuses on reducing execution timeof applications that require a great number of computerprocessing cycles. The Data Grid provides the way tosolve large scale data management problems. Dataintensive applications such as High Energy Physics andBioinformatics require both Computational and DataGrid features. Job scheduling in Grid has been mostlydiscussed from the perspective of computational Grid.However, scheduling on Data Grid is just a recent focusof Grid computing activities. In Data Grid environment,effective scheduling mechanism considering bothcomputational and data storage resources must beprovided for large scale data intensive applications.In this paper, we describe new scheduling model thatconsiders both amount of computational resources anddata availability in Data Grid environment. Weimplemented a scheduler, called Chameleon, based onthe proposed application scheduling model. Chameleonshows performance improvements in data intensiveapplications that require both large number ofprocessors and data replication mechanisms. Theresults achieved from Chameleon are presented.
