Parallel programs are typically written in an explicitly parallel fashion using either message passing or shared memory primitives. Message passing is attractive for performance and portability since shared memory machines can eeciently execute message passing programs, however message passing machines cannot in general eeectively execute shared memory programs. In order to write a parallel pro...

We present a small, extensible interface for the transparent communication between vendor speci c and standard message-passing environments. With only four new commands, existing parallel applications can make use of our PLUS communication interface, thereby allowing inter-process communication with other programming environments. Much e ort has been spent in optimizing the communication speed ...

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.

MPI is the new standard which deenes a set of message passing operations for multicomputers and clustered systems. In comparison to other popular message passing systems, MPI provides a richer collection of functions, allowing eecient implementations , portability and excellent support for the development of parallel libraries. In this paper, we describe the implementation and performance of MP...

The Message Passing Interface (MPI) is widely used to write parallel programs using message passing, but it does not guarantee portability between different MPI implementations. When an application runs without any problems on one platform but crashes or gives wrong results on another platform, developers tend to blame the compiler/architecture/MPI implementation. In many cases the problem is a...

Users of parallel machines need to have a good grasp for how different communication patterns and styles affect the performance of message-passing applications. LogGP is a simple performance model that reflects the most important parameters required to estimate the communication performance of parallel computers. The message passing interface (MPI) standard provides new opportunities for develo...

Multicomputer Operating System for Unix (MOSIX) is a cluster-computing enhancement of Linux kernel that supports preemptive process migration. It consists of adaptive resource sharing algorithms for high performance scalability by migrating processes across a cluster. Message passing Interface (MPI) is a library standard for writing message passing programs, which has the advantage of portabili...

This paper reports on design issues involved in combining two public-domain paradigms to create a parallel software environment for DSP programming. MPI (Message-Passing Interface), a message passing system, is an evolving standard for parallel computing. Khoros is an integrated software environment for DSP. The goal of this work is to describe and demonstrate a software design that exploits Kh...
