MPI及其Java实现

MPI and Its Implementation with Java

随着科学技术的发展 ,对计算机的并行计算技术的要求越来越高。消息传递接口MPI提供了一种很好的方法。MPIAPI可以高效地在异构环境中使用 ,并可以在众多厂商的平台上实现 ,底层的通信和系统不会有大的改变。Java语言是伴随着网络计算技术而诞生的编程语言 ,它对网络有较好的支持 ,在网络计算技术中 ,有着举足轻重的地位。许多分布式应用程序都是由Java开发的。开发一个Java版的MPI很有必要。但MPI论坛未定义MPI的Java接口。本文从MPI的基本概念入手 ,说明了如何用Java语言实现MPI。

With the development of the science and technology, the demand for the parallel computation technology of the computer is getting more and more. For which, the appearance of the Message-Passing Interface (MPI) has provided a very good method. The MPI API can run efficiently in the heterogeneous environment, and be implemented above the platforms of many vendors, almost without changing the bottom communication and system. In the field of computation upon networks, Java is very important. Many distributed application programs are developed with Java. But, MPI Forum does not define the interface for Java.This paper begins with the MPI basic concepts, and demonstrates how to implement MPI with Java.
