To make final small changes to improve hardware or software performance ; to fine - tune a nearly complete product 为改进软件或硬件性能,对产品进行最后定型之前的修饰和润色。
Because hpm events can record performance data such as level 1 cache which revealing software performance , from year of 2000 to now , many performance analysis models and tools using hpm events be introduced 这些性能数据从系统运行的最底层反映了cpu的性能表现和当前的性能状态。另一方面, cpu的运行状态也就决定了软件运行的性能和状态。
The paper introduced two large vr development software : multigen and opengvs , and depictioned the software performance , module function and so on , analysed and compared strong points and weak points . all these has provided a strong foundation for the future development 介绍了两个大型的虚拟现实开发工具multigen和opengvs ,详细叙述了两个工具软件的性能、模块功能等主体内容,分析比较了它们的优缺点,为后期的系统开发奠定了坚实的基础。
Such as , booting successfully after restoring the partition data , recognizing the volume characters , compressing data and checking data integrity , etc . to make the backuping and restoring operation better , the paper presents much test datas , and want to use the reliable data and the analyse on these data to get the best i / o memory size , the fastest i / o speed and the correct partition table modifying method . they will improve the software performance wholly 为了能更好的实现磁盘备份恢复操作,论文列示了很多在研究过程中通过实验积累的测试数据,力求能用详实的数据,对这些数据进行的综合分析,来获得较佳的读写数据内存块大小,较快的数据读写速度,较正确的读写分区表数据的方法,从而提高应用软件的整体性能。
Excepting algorithms self , the software performance analysis and optimization always relate to the multi - hiberarchy storage archtechture , trying to utilize the nearside storage media such as register or level 1 cache and reduce actions on farside storage , and try to reach a linear performance , i . e . the computing performance only relate to the speed of cpu clock 现在的软件性能分析及其相关的性能优化,除了程序本身算法之外,几乎所有的分析和优化都是在这样一个多级的存储体系结构上进行的,试图尽可能地利用近端的存储,期望达到一个接近线速的计算性能,即计算的性能仅由cpu的处理速度决定,与其他外设和数据存储无关。
This paper introduces two great development software which are multigen and opengvs and depicts the software performance , module function and so on . it has provided a strong foundation for the future development . the downhole operation simulation system is realized , which based on the desktop operating system using the software performance of multigen and opengvs 介绍了三维建模软件multigen和三维视景管理软件包opengvs组成的虚拟仿真开发平台,详细叙述了两个工具软件的性能、模块功能等主体内容,为后期的系统开发奠定了坚实的基础。
