JavaSymphony, a Programming Model for the Grid

摘要

In previous work, JavaSymphony has been introduced as a high level programming model for performance-oriented distributed and parallel Java programs. We have extended JavaSymphony to simplify the development of Grid applications written in Java, allowing the programmer to control parallelism, load balancing, and locality at a high level of abstraction. In this paper, we introduce new features to support the widely popular workflow paradigm. The overall idea is to provide a high level programming paradigm that shields the programmer from low level implementation details such as RMI, sockets, and threads. Experiments will be shown to demonstrate the usefulness of JavaSymphony as a programming paradigm for the Grid.
