使用Windows脚本更改进程的相似性 [英] Change affinity of process with windows script

问题描述

在Windows中，

 START /node 1 /affinity ff cmd /C "app.exe"

我可以设置app.exe的相似性（app.exe使用的内核数）。

I can set the affinity of app.exe (number of cores used by app.exe).

使用Windows脚本，如何更改正在运行的进程的相似性？

With a windows script, How I can change the affinity of a running process ?

推荐答案

PowerShell可以为您完成此任务

获取关联性：

PowerShell can do this task for you

Get Affinity:

PowerShell "Get-Process app | Select-Object ProcessorAffinity"

设置相似性：

Set Affinity:

PowerShell "$Process = Get-Process app; $Process.ProcessorAffinity=255"

示例：（8核处理器）

• 核心编号 = 值 = BitMask


• 核心1 = 1 = 00000001


• 核心2 = 2 = 00000010


• 核心3 = 4 = 00000100


• 核心4 = 8 = 00001000


• 核心5 = 16 = 00010000


• 核心6 = 32 = 00100000


• 核心7 = 64 = 01000000


• 核心8 = 128 = 10000000



Example: (8 Core Processor)

• Core # = Value = BitMask
• Core 1 = 1 = 00000001
• Core 2 = 2 = 00000010
• Core 3 = 4 = 00000100
• Core 4 = 8 = 00001000
• Core 5 = 16 = 00010000
• Core 6 = 32 = 00100000
• Core 7 = 64 = 01000000
• Core 8 = 128 = 10000000

只需将十进制值加到要使用的内核上。 255 =所有8个内核。

Just add the decimal values together for which core you want to use. 255 = All 8 cores.



• 所有内核= 255 = 11111111



C:\>PowerShell "Get-Process notepad++ | Select-Object ProcessorAffinity"
