SIMULATOR INTERFACE FOR A WIDE-AREA GRID SYSTEM

Abstract

Super scheduling, a scheduling process involving resources of multiple administrative domains, is one of the main challenges of Grid Computing. An efficient job scheduler utilizes systems more efficiently while enabling higher throughput for the user. As it is very time-consuming to perform experiments, doing simulation enables the user to evaluate the performance of algorithms under different Grid environments. The work here revolves around the creation of a Graphical User Interface for the Super Scheduler simulator that enables a user to create a dynamic Grid of many administrative domains by using drag-and-drop, and thereafter to run a simulation of this Grid environment using several different algorithms and parameters. Using these different scenarios, the user can evaluate how bandwidth variation, computation duration, dataset size and job arrival interval can impact the average response time, average stretch and data transfer times.
