Java Versus MPI in a Distributed Environment
نویسندگان
چکیده
Networked unix workstations as well as workstations running Windows 95 or Windows NT are fast becoming the standard computing environments at many universities and research sites. Researchers and educators seek simple methods to harness the potential for parallelism implicit in these computing networks. This paper investigates the ease and efficiency of Java sockets, Java remote method invocation (RMI), and Message Passing Interface (MPI) to address these needs. We look at the ease of programming in each of the environments and efficiency considerations using sequential programs as a base mark. For certain applications, Java may not be the best choice, but in other cases, Java provides a simple, robust distributed programming environment.

Wrapping MPI-based legacy codes as Java/CORBA components
Techniques for wrapping an MPI-based molecular dynamics (MD) simulation code as Java/CORBA components, for use within a distributed component based problem solving environment (CB-PSE), is presented. A legacy code for simulating a Lennard–Jones fluid is first wrapped as a single CORBA object, followed by division of the code into computational sub-units, where each sub-unit is wrapped as a CORB...
متن کاملAn Overview of Portable Distributed Techniques
In this paper, we reviewed of several portable parallel programming paradigms for use in a distributed programming environment. The Techniques reviewed here are portable. These are mainly distributing computing using MPI pure java based, MPI native java based (JNI) and PVM. We will discuss architecture and utilities of each technique based on our literature review. We explored these portable di...

MPI is a de facto standard for message passing for high performance parallel, as well as, for distributed computing environment. The static and homogenous model of MPI is not compatible with the dynamic and heterogeneous Grid environment. There are not many implementations which offer message passing over Internet and Grids. P2P-MPI and A-JUMP are MPI implementations, which provide both point-t...
متن کاملDistributed multiscale computing with MUSCLE 2, the Multiscale Coupling Library and Environment
We present the Multiscale Coupling Library and Environment: MUSCLE 2. This multiscale componentbased execution environment has a simple to use Java, C++, C, Python and Fortran API, compatible with MPI, OpenMP and threading codes. We demonstrate its local and distributed computing capabilities and compare its performance to MUSCLE 1, file copy, MPI, MPWide, and GridFTP. The local throughput of M...
