Future-based RMI: Optimizing compositions of remote method calls on the grid

Abstract

We argue that the traditional RMI (remote method invocation) mechanism causes much unnecessary communication overhead in Grid applications, which run on clients and outsource time-intensive method calls to high-performance servers. We propose future-based RMI, an optimization to speed up compositions of remote methods, where one method uses the result of another method as an argument. We report experimental results that confirm the performance improvement due to the future-based RMI on a prototypical Grid system on top of Java. © Springer-Verlag 2003.
