Why P scales as C*V^2*f is so obvious (pt 2)

THE GORY DETAILS

Let’s continue from where we left off last time. Let’s figure out the why of the equation,

P = C * V^2 * (a * f)

在Intel®平台上优化多媒体应用程序功耗

经过多年的硬件平台优化,硬件平台功耗逐年降低。CPU有了新的低功耗状态,显示功耗也大幅下降。然而,运行在平台上的软件所产生的功耗问题却越来越明显。在软件方面,多媒体应用程序对功耗的影响更加引人关注。事实上,研究表明优化过的多媒体应用程序播放时间是未优化过的媒体程序的两倍多。

诊断信息 15532: 循环无法进行矢量化处理:编译时间不足妨碍了循环进行优化

产品版本: Intel(R) Visual Fortran 编译器 XE 15.0.0.070

原因:

使用 Visual Fortran 编译器的优化选项 ( -O2  -Qopt-report:2 )  时出现矢量化报告,表示编译时间不足妨碍了优化。
