为什么Visual Studio无法在多个内核上运行? CPU 25％ [英] Why can't Visual Studio run on more than one core? CPU at 25%

问题描述

我正在运行带有噩梦般的MS测试框架的Visual Studio 2008.麻烦的是它正在将我的CPU发送到100％(四核上是25％).

I'm running Visual Studio 2008 with the stuff-of-nightmares awful MS test framework. Trouble is that it's sending my CPU to 100% (well 25% on a quad-core).

我的问题是为什么Visual Studio无法在多个内核上运行? M $当然必须在线程上有足够的处理能力才能使它起作用.

My question is why can't Visual Studio run on more than one core? Surely M$ must have a sufficient handle on threading to get this to work.

推荐答案

我在所有4个CPU上都运行了VS2008.只需设置此环境变量/项目标志即可.

I have VS2008 running on all 4 CPUs. Just set this environment variable / project flag.

/MP

(可以在"C/C ++设置"的高级"中设置.在项目设置中)

(It can be set in C/C++ Settings, Advanced. In project settings)

MP标志还可以接受数字，例如/MP2，这意味着它将仅在2个内核上运行.将其保留为/MP意味着它将在最大数量的内核上运行.

The MP flag can also accept a number, e.g. /MP2 which means it will only run on 2 cores. Leaving it as just /MP means it will run on the maximum amount of cores.

Edit2:MP标志可能仅适用于编译器.

The MP flag is probably for the compiler only.
