The research on the binary translation and the related optimization has signality not only for legacy code migration but also for the program performance improvement and other aspect 二进制翻译及相关优化技术的研究,不仅在遗产代码移植而且在程序性能提高等其它方面都有重要的意义。
They also give you a more comprehensive view of program performance because they gather timing information for every method call , not just a particular section of the code 它们还为程序性能提供了更全面的观察,因为它们收集每个方法调用的计时信息,而不仅仅是某个具体代码段的计时信息。
Dynamically allocated linked lists can reduce program performance because when you search for an item or when you traverse a list to the end , each skipped link could miss the cache or cause a page fault 动态分配的链接表可以降低程序性能,因为当搜索项或者在表中遍历到末尾时,每个跳过的链接都可能未命中缓存或导致页错误。
If the drug manufacturer is using such a program to control or monitor a significant process , determine what steps the firm has taken to assure itself that such program blind spots do not compromise the program performance 如果制药商通过这一程序来监控重要的工艺,就要确定公司要采取的方法,以确保程序盲点不会影响程序的执行。
Atmosphere : this meeting was about 35 people attended , basically everyone involving in the program performances , and members felt of the central performances , watching members of the department also actively involving 氛围:这次会有大概35人参加,基本上所有人都参与了节目的表演,表演中部员尽情发挥,观看的部员也积极参与进来!
However , the oop method is provided with very powerful expansibility and maintainability . it is not difficult to include more functional modules or class modules , to extend the program performance 然而,由于oop方法具有极强的可扩充性和可维护性,因此,不难在此基础上将其它功能模块或类模块包含进来,从而使程序功能不断得到加强。
Compilers can automatically transform such methods into loops and thereby improve program performance , but this transformation is not required by the java language specification , so not all jvms will perform it 编译器会自动把这种方法转换成循环,以提高程序的性能。但在java语言规范中,并没有要求一定要作这种转换,因此,并不是所有的java虚拟机( jvm )都会做这种转换。
Program performance measurement - as the first step of program performance optimization , recognizes the bottleneck of the program performance to find out the utilization ratio of software / hardware resources and the machine ' s performance by understanding program behaviors 它的第一步工作? ?程序性能测试通过理解程序行为,来识别程序性能瓶颈,以了解软/硬件资源利用情况和程序对机器性能的发挥程度。
A parallel program performance analysis system based on the frame model is developed to analyze performance of parallel programs . the system is used to analyze parallel programs that use mpi as the parallel support environment . it has good portability and is easy to use 基于这个系统框架设计并实现了相应的并行程序性能分析系统,该性能分析系统主要针对基于mpi的并行应用程序,其可移植性较好,简单易用。
This thesis mainly focuses on the multi - level parallelism development and performance optimization of scientific programs on this architecture , and our works are summarized as follows . ( 1 ) we put forward the multi - level parallel computing time model , which is suitable for smp cluster to analyze program performance from the micro - aspect . we also provide a multi - level parallel optimization speedup model based on the single - processor speedup factor , which can evaluate program performance from three parallel levels and guide us to improve the programs 本文围绕这种多级并行体系结构中的超节点级、节点级和单机指令级三个层次的并行性开发与优化,在科学计算程序的综合优化技术研究方面做了以下的工作与创新: ( 1 )针对smp集群体系结构提出了多级并行计算时间模型,用于程序性能的微观分析;将单机处理速度与加速比统一起来,提出了基于单机优化加速因子的多级并行优化加速比评价模型,该模型分别从三个并行层次的角度出发对程序性能进行评价,并指导对程序的改进与优化。
