Parallel programming has its own special place in computing ; part 2 of this series examines parallel programming platforms and examples 并行编程在计算中有自己特殊的地位：本系列文章的第2部分将介绍并行编程平台，并给出几个例子。
Parallel programming like all programming is as much art as science , always leaving room for major design improvements and performance enhancements 并行编程（与所有的编程技术一样）与其他科学一样，都是一门艺术，总会留下一定的空间来进行设计的改进和性能的提高。
The cluster system maybe consists of heterogeneous computer system , but the current parallel programming environment ca n ' t cross the different operate systems to execute parallel computing 机群系统具有异构性，现有的并行编程环境存在不能跨越异构操作系统的问题，不能跨平台进行并行计算。
A good thing about pvfs is that it allows binaries meant for regular filesystems to run on it without modification - this is somewhat of an exception in the parallel programming arena 有关pvfs有一件好的事情：不需做任何修改就可以在其上运行普通文件系统的二进制形式这在并行编程领域多少是个例外。
In this article , we study the key technologies of pems and focus on implementing of the multiprocessor communication mechanism , which make it possible for pems to support coarse - grained parallel programming pattern 本文对pems中的关键技术进行了研究,重点实现了pems中的基于共享内存的多处理器通信机制,为应用提供了粗粒度并行编程模型。
But , because of the particularity of the architecture of the cluster system , programmers have to face the heterogeneous of the cluster system , and should be familiar with the specialized knowledge of system operating and cluster managing 但由于机群系统结构的特殊性，在进行基于机群系统的并行编程时，程序员并不能真正地将机群系统当作一台计算机来使用。
The model of distributing threads over the grid using java distributed parallel programming environment to create a master programming models , so grid application developers can also chooses a number of distributed computing model based on grid applications 网格分布式线程设计模块利用java的分布式并行编程环境,建立一个集成编程模型,让网格应用程序开发者能同时选择多个基于网格应用程序所需要的分布式计算模型。
The main work is summarized as follows : ( 1 ) we analyze the situation of the parallel computing technology and it ' s influence on numerical forecasting models , and point out that the numerical models now are in serious demand for efficient parallel algorithms 本文的主要研究成果概括如下： ( 1 )讨论了数值并行计算技术的发展现状及其对数值预报模式的影响，深入研究了并行计算模型、并行编程模型和数值并行软件的软件工程等问题。
Based on above theoretical bases , in this paper an optimal control model of master / slave parallel genetic algorithm to solve dta problem is proposed . based on the drawing cluster with distributed storage and message passing system , this algorithm is implemented in the master / slave mode of the pvm parallel platform 在上述理论基础上，实现了最优控制动态交通分配的主从式并行遗传算法，并在基于分布式存储和消息传递体系结构的曙光机群系统下，应用并行编程环境pvm下master slave模式完成了上述算法。
