In the distributed computing based on message passing, mpi is a popular message passing interface library in parallel programming 在基于消息传递的分布式计算中,mpi(messagepassinginterface)是广受欢迎的消息传递接口函数库。
Among them, mpi ( message passing interface ) is the most important program paradigm . it has many advantages, such as portable, powerful and high efficient 其中mpi(消息传递接口)是目前最重要的编程工具,它具有可移植性好、功能强大、效率高等多种优点。
The open standard message passing interface and any of several variations are often included as part of the grid system for just this kind of communication 消息传递接口(messagepassinginterface,mpi)是一项开放标准,它及其若干变种经常作为网格系统的一部分来解决诸如此类的问题。
Mpibd ( message passing interface binding delphi ) presented in this paper is a distributed parallel computing environment constructed on the mpi-communication-library bound with delphi 我们开发的mpibd(messagepassinginterfacebindingdelphi)是在建立绑定delphi的mpi通信库基础上构架的一个分布式并行计算环境。
This paper uses the idea of hpec _ si ( high performance embedded computing software initiative ) for reference, basing on the message passing mechanism of mpi ( message passing interface ), envelops some typical parallel algorithms in image / signal processing domain as classes, and designs and finishes an object-oriented 、 image / signal processing standard parallel library to provide application software programmers an excellent development environment 本课题借鉴高性能嵌入式计算软件计划(highperformanceembeddedcomputingsoftwareinitiative,hpec_si)的解决方法,基于消息传递接口(messagepassinginterface,mpi)的消息传递机制,对图像/信号处理中的一些典型并行算法以类组件的方式进行封装,设计和实现了具有面向对象特征的、用于图像/信号处理的并行向量库,提供给应用软件开发人员一个良好的开发环境。
