PassingSystems : Experiences with PVM - RPC ?
نویسنده
چکیده
The relationship between client-server distributed computing and message-passing parallel processing is explored in this work through an experimental RPC framework for the PVM system. The project investigates the potential for RPC to complement asynchronous message passing in PVM { both to expand the domain of applications, and to evaluate the eeectiveness of client-server computing for traditional scientiic and numerical problem solving. Our design is intuitive and straightforward, and enables servers and clients to be developed with a minimum of additional eeort in terms of programming and logistics. Our experiences with early implementations of PVM-RPC indicate that the client-server model is reasonably compatible with message passing and scientiic algorithms, and furthermore, that the RPC layer introduces little if any performance overhead into message passing systems. Furthermore, support for simple versions of useful features such as transparent failure resilience and automatic load balancing are facilitated in this model.

متن کاملA Performance Evaluation of Rpc, Java Rmi, Mpi and Pvm
This paper presents performance comparison of Remote Procedure Calls (RPC), Java Remote Machine Invocation (RMI), Message Passing Interface (MPI) and Parallel Virtual Machine (PVM). The Bandwidth, latency and parallel processing time are measured using standard benchmarks. The results show that the MPI performance is much closer to RPC performance.

Due to their ever-growing success in the development of distributed applications , today's multithreaded environments have to be highly portable and ee-cient on a large variety of hardware. Most of these environments have an implementation built on top of standard communication interfaces such as PVM or MPI, which are widely available on existing architectures. Obviously, this approach ensures ...
