Abstract : high - performance computer technique is one of the important signs of iudging a country ' s science and technical level and synthetical national power . now , some developed countries in world are positively investing huge funds for its development and study . pc cluster system is the cheappest one . the paper emphatically discusses some key technologies used for deploying a cluster system , such as scalability , availability , resource management , load balancing and parallel programming environment etc , and it also gives a mpi , parallel computing instance . at the same time , according to characteristics of a cluster system , it presents the practical significance of such a system in diverse fields 文摘:高性能计算机技术是衡量一个国家科技水平及综合国力的重要标志之一，目前世界上一些发达国家都在争相投入巨额资金对它进行开发和研究. pc集群计算机就是最廉价的高性能计算机.着重讨论了集群计算机系统构建中的一些关键技术，如可扩展性、可用性、资源管理、负载平衡和并行程序设计环境等,并给出了一个基于mpi环境的并行程序设计实例，同时,也根据集群系统的特点提出了它在不同领域中的实用意义
It is the primary concern what any such skeleton - oriented parallel computation model should confront . we , however , less than once find correspondent . give out the compare between of current skeleton - oriented parallel programming ; propose providing a unified parallel programming model without exacting unified parallel computation model 但我们至今还没有看到过有相应的探讨；对面向skeleton的并行程序设计方法进行了比较；倡导提供统一的并行程序设计模型，而不苛求统一的并行计算模型。
