performance n. 1.執(zhí)行,實(shí)行,履行;完成;實(shí)現(xiàn);償還。 2.行為,動(dòng)作,行動(dòng);工作。 3.性能;特性。 4.功績;成績。 5.演奏;彈奏;演出;(馴獸等的)表演;把戲。 6.【物理學(xué)】演績。 a performance test 【機(jī)械工程】性能試驗(yàn)。 high performance 高度準(zhǔn)確,性能優(yōu)良。 an afternoon performance 午后的演出,日戲。 two performances a day 一天演兩場。 a fine [wretched] performance 成績好[壞]。 put a monkey through its performances 使猴子玩種種把戲。 performance in [of] horse-manship 馬戲;馬術(shù)表演。
To make final small changes to improve hardware or software performance ; to fine - tune a nearly complete product 為改進(jìn)軟件或硬件性能,對產(chǎn)品進(jìn)行最后定型之前的修飾和潤色。
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 這些性能數(shù)據(jù)從系統(tǒng)運(yùn)行的最底層反映了cpu的性能表現(xiàn)和當(dāng)前的性能狀態(tài)。另一方面, cpu的運(yùn)行狀態(tài)也就決定了軟件運(yùn)行的性能和狀態(tài)。
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 介紹了兩個(gè)大型的虛擬現(xiàn)實(shí)開發(fā)工具multigen和opengvs ,詳細(xì)敘述了兩個(gè)工具軟件的性能、模塊功能等主體內(nèi)容,分析比較了它們的優(yōu)缺點(diǎn),為后期的系統(tǒng)開發(fā)奠定了堅(jiān)實(shí)的基礎(chǔ)。
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 為了能更好的實(shí)現(xiàn)磁盤備份恢復(fù)操作,論文列示了很多在研究過程中通過實(shí)驗(yàn)積累的測試數(shù)據(jù),力求能用詳實(shí)的數(shù)據(jù),對這些數(shù)據(jù)進(jìn)行的綜合分析,來獲得較佳的讀寫數(shù)據(jù)內(nèi)存塊大小,較快的數(shù)據(jù)讀寫速度,較正確的讀寫分區(qū)表數(shù)據(jù)的方法,從而提高應(yīng)用軟件的整體性能。
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 現(xiàn)在的軟件性能分析及其相關(guān)的性能優(yōu)化,除了程序本身算法之外,幾乎所有的分析和優(yōu)化都是在這樣一個(gè)多級的存儲(chǔ)體系結(jié)構(gòu)上進(jìn)行的,試圖盡可能地利用近端的存儲(chǔ),期望達(dá)到一個(gè)接近線速的計(jì)算性能,即計(jì)算的性能僅由cpu的處理速度決定,與其他外設(shè)和數(shù)據(jù)存儲(chǔ)無關(guān)。
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 介紹了三維建模軟件multigen和三維視景管理軟件包opengvs組成的虛擬仿真開發(fā)平臺(tái),詳細(xì)敘述了兩個(gè)工具軟件的性能、模塊功能等主體內(nèi)容,為后期的系統(tǒng)開發(fā)奠定了堅(jiān)實(shí)的基礎(chǔ)。
