Abstract: Grid is a type of parallel and distributed computing environment. Alchemi is one of the open source toolkit for implementing grid environment. In Alchemi, Grid manager provide services associated with managing the execution of grid applications and their constituent thread. When a client node sends request to the manager or entry portal node, which distributes jobs among the executor or worker node. Here the threads are scheduled on a priority and First Come First Served (FCFS) basis. Most previous research on job scheduling for heterogeneous system considers the scenario where each job or task is mapped into single processor. In this study, we address the scheduling of parallel jobs in grid environment, where each site has a homogeneous cluster of processor, but processor at different sites has different speed. Here, we use Highest Response Next scheduling scheme where jobs are allotted to number of processor based on job�s priority and processor�s capability. This scheme is adaptive for local jobs and remote jobs without any loss of performance and highly adaptive for grid environment.
