多核CPU上的单线程应用程序 [英] Single thread application on a multi core CPU

问题描述

我的初学者问题是这个.

假设我们有一台装有i5 cpu的计算机，并且制作了一个单线程应用程序.

多余的内核是否对应用程序无用，仅使用1个cpu?

操作系统是否会将应用程序进程划分为多个cpu?

单核cpu和多核cpu的速度会有所不同吗?

谢谢.

My beginner question is this.

Let''s say we have a computer with an i5 cpu and we made a single threaded application.

Will the the extra cores be useless for the application, and will it just use only 1 cpu?

Will the operating system split the application process in more than one cpu?

Will speed be any different between a single core cpu and a multi one?

Thanks.
