Application to set CPU Affinity

[wayliff]

Is there a way or a piece of software that can set the CPU affinity and keep it?

Wondering...I got a x2 3800+ and I just dont want to deal with this change every time I reboot.

Also is there a preferred settings for the CPU affinity that brings some efficiency?

Thanks

You could create a shortcut that uses the "start" command to run it with a specific affinity, plenty more information about app affinity here:

Unless you're running into problems with most apps it's best to leave it alone and let the OS manage.

What apps are you working with that you're trying to set the affinity on? What's your hardware configuration?

I only set the affinity on the Distributed Computing application...just thinking it will run better on a single core.

AMD athlon 64 x2 3800+
2 x 512 of ram
Epox Nforce 4 board
ATI Radeon x800xl

really dont have any problems at the time...

I remember games that I had to set affinity to keep their silly cd checkers from crashing, *kicks EA in the balls

If your goal is to keep DC disruption to a minimal than yeah running it on a single CPU/Core would probably be best; if your goal is highest output than I would leave it as-is (especially if your DC app is SMP capable).

If you're really interested in persuing you might consider a post in the DC forums regarding stratagy.

Yeah there are some apps out there (generally poorly written) that have issues; this is generally the only time that I'd bother with setting processor affinity for an app.

cool thanks for the info

I did this, here is my Target:

C:\WINDOWS\system32\cmd.exe /C start /AFFINITY 1 D:\Games\Oblivion\OblivionLauncher.exe

When I click the game icon nothing happens, all it looks like it's trying to do is just lauch the cmd prompt.

THANKS

Ok I'm using Launch n Set:

seems like a cool little app, I wrote to the devloper to make some changes to it, I hope he'll consider.

THANKS

Sure you have your paths right?
cmd.exe /C start /AFFINITY 1 c:\Windows\System32\notepad.exe
works fine for me (I dont have oblivion)

 

[DasFox]

Yes I have the paths correct, again all I see in the upper left hand of the desktop is the cmd prompt flash on and off.

THANKS

Same thing happens for me.

What could the problem be?

If the paths are incorrect, it will display an error message. So I know for sure the paths I have are correct.

If your game is in program files, or any folder with spaces add the qoutes so that windows will interpret the string correctly.
for example...
C:\WINDOWS\system32\cmd.exe /C start /AFFINITY 1 "D:\Program Files\Oblivion\OblivionLauncher.exe"
