an efficient implementation of java s Remote Method Invocation
ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming, 1999Co-Authors: Jason Maassen, Henri E Bal, Rob V Van Nieuwpoort, Ronald Veldema, Aske PlaatAbstract:Java offers interesting opportunities for parallel computing. In particular, Java Remote Method Invocation provides an unusually flexible kind of Remote Procedure Call. Unlike RPC, RMI supports polymorphism, which requires the system to be able to download Remote classes into a running application. Sun's RMI implementation achieves this kind of flexibility by passing around object type information and processing it at run time, which causes a major run time overhead. Using Sun's JDK 1.1.4 on a Pentium Pro/Myri.net cluster, for example, the latency for a null RMI (without parameters or a return value) is 1228 μsec, which is about a factor of 40 higher than that of a user-level RPC. In this paper, we study an alternative approach for implementing RMI, based on native compilation. This approach allows for better optimization, eliminates the need for processing of type information at run time, and makes a light weight communication protocol possible. We have built a Java system based on a native compiler, which supports both compile time and run time generation of marshallers. We find that almost all of the run time overhead of RMI can be pushed to compile time. With this approach, the latency of a null RMI is reduced to 34 μsec, while still supporting polymorphic RMIs (and allowing interoperability with other JVMs).

wide area parallel programming using the Remote Method Invocation model
Concurrency and Computation: Practice and Experience, 2000Co-Authors: Rob V Van Nieuwpoort, Jason Maassen, Thilo Kielmann, Henri E Bal, Ronald VeldemaAbstract:Java’s support for parallel and distributed processing makes the language attractive for metacomputing applications, such as parallel applications that run on geographically distributed (wide-area) systems. To obtain actual experience with a Java-centric approach to metacomputing, we have built and used a high-performance wide-area Java system, called Manta. Manta implements the Java Remote Method Invocation (RMI) model using different communication protocols (active messages and TCP/IP) for different networks. The paper shows how widearea parallel applications can be expressed and optimized using Java RMI. Also, it presents performance results of several applications on a wide-area system consisting of four Myrinetbased clusters connected by ATM WANs. We finally discuss alternative programming models, namely object replication, JavaSpaces, and MPI for Java.

MobileRMI: upgrading Java Remote Method Invocation towards mobility: Research Articles
Software - Practice and Experience, 2005Co-Authors: Marco Avvenuti, Alessio VecchioAbstract:Code mobility is recognized as a promising design technique, able to improve flexibility, adaptability and bandwidth utilization in mobile computing applications. To promote and facilitate its use, researchers argue that code mobility should be made available to programmers in combination with, and not as an alternative to, more traditional programming models. This paper describes the design and implementation of the MobileRMI toolkit which, unlike agent-based systems, enables mobility-based programming within a widely accepted middleware platform, Java Remote Method Invocation (RMI). Our toolkit provides a set of mobility primitives that allow programmers to create, clone and move Remote objects across a network. To preserve location transparency we implemented a novel, efficient scheme for automatically updating Remote references by exploiting the distributed garbage collector. Programming examples are given and a case study where an adaptive application uses logical mobility to minimize communication over a mobile ad hoc network is presented. Experience from using MobileRMI confirmed the benefit of designing both static and mobile applications within the same programming framework. Copyright © 2005 John Wiley & Sons, Ltd.
