| Abstract: | The communication technology has made possible the cluster and grid computing. PVM (Parallel virtual Machine) a layer on linux operating system, provides cluster computing environment in a Local Area network. The scheduling used by PVM does not make use of any state information of individual participating nodes and as a result its performance is sub-optimal. The work envisages devising a dynamic scheduling strategy that improves the performance in terms of turnaround time and speedup. The influence of various static and dynamic parameters is studied through experiments and a goodness value is derived to measure the load at the participating nodes. The goodness value computed is used to schedule the tasks on the nodes. The performance measured in terms of turnaround time and speedup is compared with the existing PVM scheduler. |
