Set CPU Affinity prior to app launch?

I would also appreciate the answer to this! Great question.

Until now, I didn't know you could set affinity of any program from Task Manager.

I'd love an answer to this as well. It would be nice to have all processes run on one core and your games on the other without having to manually set the affinity each time.

LMAO. Well now I don't feel like such a noob. I guess if ya gotta ask a question, better make it a good one, eh?

Ya, you can set affinity from Process in Task Manager, but it's WHILE the app is running.

Someone, somewhere, at sometime.....told me how to do it, but I've long since forgotten

LOL.

Can we get a 6th???

As far as I know, there are no way to preset affinities with Task manager.

I think this is the application to set affinity that you're mentioning.

I'm linking to the official source here:

Also a google caché of the same page because AMD forums were under repair at the moment...

I read in that site that now you don't need to modify the exe to make it work. I sincerely didn't test it so don't complain if that program misteriously wipes out all your pr0n. I can't find mine, thats for certain. (??)

Hope it helps and as usual, sry for my english!

here's one way to do so...if you're interested you can get the source code (on the left and check how they do it) else just download the binary

I always used "Firedaemon" myself for this specific purpose, well at least for starting my game server on specific cores. Never tried it with any regular applications.

hmmm...I'm kinda tempted to write a little tray app that lets you add processes to a list and auto changes their affinity and priority. Really should be doing my own work tho!

That imagecfg link is interesting. Not sure how it works, I can't remmeber if there is a var for affinity in the PE headers or not.

Yea. The THG Task Assignment Program is very usefull. I have used it often recently, as long as TaskAssign.exe is running in memory (Assuming you have already Set Processor Affinity) it will run the Specified Application(s) in it's App List, using the processor you have specified.

If you dont't want people to help in this forum, just say it; and in order to prevent other users, first check if you are right or not with that kind of affirmations. I'm offering for free a software of my property, and I think I deserve a little of respect. So, if you don't trust, the answer is easy: don't click.
One more thing, I just registered to post this link to give people a solution that I made for myself, and I wanted to share it. Perhaps, Scotteq, you're not as smart as you pretend to. No more to say.

I know this is an old thread, but here's the easy answer that didn't come up. WinXP (and also Vista, I believe) has a utility included called start. This utility can be used to run a program with a specified cpu affinity. the command would look like this:

start /affinity xx myprogram.exe

Use the actual name of the program you want to run, of course, and substitute xx for a hex number representing the affinity you want as follows:

01 - 1st CPU
02 - 2nd CPU
03 - 1st and 2nd CPU
04 - 3rd CPU
05 - 1st and 3rd CPU
...
etc
