Abstract

Grids are facing the challenge of seamless integration of the Grid power into everyday use One critical component for this integration is responsiveness the capacity to support ondemand computing and interactivity Grid sched uling is involved at two levels in order to provide responsiveness the policy level and the implementation level The main contributions of this paper are as follows First we present a detailed analysis of the performance of the EGEE Grid with respect to responsiveness Second we examine two userlevel schedulers located between the general scheduling layer and the application layer These are the DIANE distributed analysis environment framework a generalpurpose overlay system and a specialized embedded scheduler for gPTM3D an interactive medical image analysis application Finally we define and demonstrate a virtualization scheme which achieves guaranteed turnaround time schedulability analysis and provides the basis for differentiated services Both methods target a brokeringbased system organized as a federation of batchscheduled clusters and an EGEE implementation is described
