Interactive Application Scheduling with GridRPC

Abstract

GridRPC is known as an effective programming model to develop Grid applications. However, it is still difficult for non-expert users to apply it efficiently. For example, a GridRPC application user needs to select computational resources, monitor the resources and estimate the application performance on the resources. In this paper, we propose InterS, an interactive scheduling system for GridRPC applications. First, the automatic scheduling mechanism provides resource allocation plans, from which the user can choose the most suitable one. Second, the execution advice mechanism helps the user to improve the performance of the application at run time while overload or failure on the resource(s) is(are) detected. Third, the scheduling policy mechanism provides the user with an interface in ClassAd format to define the scheduling policy applied in InterS. This paper also presents experimental results to show the advantage of interactive scheduling and how they can be performed at run time.
