Object Clustering for High Performance Parallel Computing

In this article we present a new parallel programming environment, called distributed object-oriented virtual computing environment (DOVE), for clustered computers based on distributed object model. In DOVE, a parallel program is built as a collection of concurrent objects each of which has its own computing power and which interacts with one another by remote method invocation. The parallelism is encapsulated within distributed objects, which can be handled the same way as local objects. The main goal of DOVE is to provide users with an easy-to-use transparent parallel programming environment while supporting efficient parallelism encapsulated and distributed among objects. For the experiment and evaluation of DOVE, two parallel application programs have been developed both on DOVE and PVM.
