Use specific CPU for different application in Windows Vista

Tech Advice:1

This is one of the most amazing features of Windows Vista that allows you to use a specific CPU for an application. You can assign one cpu to one application and other cpu for other

application.

This feature is only accessible if you are using a Dual Core or Core2Duo or a Quad Core CPU.

In order to enable this feature, you will have to pass the affinity flag to the start utility in command prompt.

For example, if you want to use CPU0 to paint brush, then type the following command at the command prompt window:

c:\windows\system32\cmd.exe /C start /affinity 1 mspaint.exe

You will notice that CPU0 is assigned to paint brush application.

To assign the same application to another CPU, you can use the following command:

For CPU0

/affinity 1

For CPU 1, use this switch:

/affinity 2

You can assign different cpu’s to different application depending on the number of cores in your CPU.
