高性能计算机,通常是指10万元以上的服务器,其概念远非普通 PC 所能比较。由于蕴涵大量、高端的 IT 技术,可以看作是计算机行业实力的表现,对国民经济和社会的发展能够起到直接的推动作用。目前,其使用范围已经从单纯的科学计算扩展到国民经济的各个行业。世界各国如美国、日本、欧洲等都在积极实施高性能计算机的计划,研究以更快的运算速度为主要发展方向,这同时也是衡量高性能计算机的一个重要指标。近年来,高性能计算机的发展呈现出两个主要趋势:首先,现在逐渐在数据仓库、数据挖掘、在线分析处理、决策支持等商业智能化和网络信息服务等领域加大力度;其次,高性能计算 High-performance computers, usually refers to more than 100,000 yuan server, the concept is far from ordinary PC can compare. Due to implication of a large number of high-end IT technology, can be seen as the performance of the computer industry, the development of the national economy and society can play a direct role in promoting. At present, the scope of its use has been extended from a simple scientific calculation to various sectors of the national economy. Countries all over the world, such as the United States, Japan and Europe, are actively implementing plans for high-performance computers and studying for faster computing speed as the main direction of development. This is also an important indicator for evaluating high-performance computers. In recent years, there are two major trends in the development of high-performance computers: firstly, efforts are being made in the fields of business intelligence such as data warehousing, data mining, on-line analysis and processing, decision support, and network information services; secondly, Calculate
