Setting Program Affinity...Permanently

[12twelve12]

I have a X2 4800 Dual Core and I know how to set the CPU affinity of different programs using Task Manager but those settings don't stay after a restart. Is there a way...a program that will allow me to set the affinity of programs and keep those settings permanently?

XP Pro

Thank you.

Correct me if I'm wrong, but currently, aren't ALL applications/services etc split equally...And that if you were to set one app to one proc you'd want to move some apps to only run off the other?

Here's a tweak you might want to look at:

Launch apps with desired priority setting

This tweak will launch most executables with the priority setting you want it to have.

Let's say you have a game installed called HIGH NEEDS and the executable is called HN.exe

Here's what to do:

-Create a new textfile in the game-app wathever-directory (let's say C:\HN), but instead of giving it the .txt extension you name it HN.bat
-Right-click this file and choose 'Edit', you'll see it'll open notepad. Put this line in:
cmd /c start /High HN.exe
-Save (make sure you save it as .bat, not as .txt) and close.

Now create a shortcut to this file and place it on your desktop. Every time you doubleclick this shortcut HIGH NEEDS will open with priority set to 'high'. (ofcourse you can also create a batchfile on your desktop, containing the full path of the app you want to start but the nice thing of creating a shortcut is you can give it an icon).

These are all the settings: Realtime, High, AboveNormal, Normal, BelowNormal, Low.

*Realtime is not recommended unless you have a dual-CPU system!

Processor priority is not the same as processor affinity. Prior to WinXP (with Win2k Reskit) there used to be a tool called imagecfg.exe that allowed you to set processor affinity automatically. If you can lay your hands on imagecfg.exe you could try to see if it works w/XP. The syntax is:
imagecfg -a 0xp C:\path\program.exe
where p is a number from 0-31 representing your processor # (0 being the first, 1 being the second etc etc)

I checked, imagecfg.exe is not available in the XP Reskit.
