A Performance Evaluation of Distributed Algorithms on Shared Memory and Message Passing Middleware Platforms (Javaspaces, CORBA‪)‬

The fundamental characteristics of a distributed computing environment are heterogeneity, partial failure, latency and difficulty of "gluing together" multiple, independent processes into a robust, scalable application. JavaSpaces, which is a shared memory paradigm, provides high-level coordination mechanism for Java easing the burden of creating distributed applications. A large class of distributed problems can be approached using JavaSpaces simple framework. JavaSpaces allows processes to communicate even if each was wholly ignorant of the others. Common Object Request Broker Architecture (CORBA), on the other hand, is a standard developed by the Object Management Group (OMG), which allows communication between objects that are written in different programming languages. It provides common message passing mechanism for interchanging data and discovering services. In this project, we compare these two platforms for distributed computing both quantitatively and qualitatively.
