JCL: A High Performance Computing Java Middleware.

Java Cá&Lá or just JCL is a distributed shared memory reflective lightweight middleware for Java developers whose main goals are: i) provide a simple deployment strategy, where automatic code registration occurs, ii) support a collaborative multi-developer cluster environment where applications can interact without explicit dependencies, iii) execute existing sequential Java code over both multi-core machines and cluster of multi-core machines without refactorings, enabling the separation of business logic from distribution issues in the development process, iv) provide a multi-core/multi-computer portable code. This paper describes JCL’s features and architecture; compares and contrasts JCL to other Java based middleware systems, and reports performance measurements of JCL applications.
