The optimal program execution time with rejuvenation 的程序執(zhí)行時(shí)間優(yōu)化算法
Program execution time 程序執(zhí)行時(shí)間
To benefit from these features , we will develope task scheduling techniques that take account of the hierarchical structure and design on - chip multiprocessing supporting mechanisms to further reduce the program execution time 為了發(fā)揮架構(gòu)特性以提升效能,我們將針對(duì)其階層特性,開發(fā)工作排程技術(shù),并開發(fā)多處理支援機(jī)構(gòu),以進(jìn)一步降低程式執(zhí)行時(shí)間。
It can lighten programmers ’ burden . the performance analysis and evaluation module analyzes speedup , efficiency and scalability and give the computation formula . this paper also brings forward a performance analysis celibrating method and a practical method to predict program execution time and communication time and analyze performance of parallel programs 性能分析與評(píng)測模塊對(duì)加速比、效率、可擴(kuò)展性等進(jìn)行分析,給出了它們的計(jì)算公式,以及性能分析的量化方法和實(shí)用的性能評(píng)價(jià)方法,預(yù)測程序通信、執(zhí)行時(shí)間,分析程序性能。
The algorithm inserts the dynamic voltage scaling code before the condition statements and after the loop statements , which affect the program execution time . the algorithm makes full use of the slack time for the running program and effectively reduces system power consumption 該算法在編譯器的幫助下,在條件語句,循環(huán)語句等影響程序?qū)嶋H執(zhí)行時(shí)間的控制語句結(jié)構(gòu)中設(shè)置電壓調(diào)節(jié)點(diǎn),插入電壓調(diào)節(jié)代碼,從而最大限度的利用了程序運(yùn)行時(shí)的空閑時(shí)間,達(dá)到了降低系統(tǒng)功耗的效果。
