CPU affinity program...

[Bladen]

I remember a topic where some dude dumped all windows and background tasks to one core of a dual core system and ran a single threaded game on its own. He attained gains of up to 15% or 20% IIRC.

I, for the life of me cannot find that topic, but someone linked a program that sets and most importantly remembers what affinity a program is assigned too. Does anyone know where to get such a freeware program?

You can do that in the Windows Task Manager.

What I mean is a small program that can be run in the background that either starts at boot or is manually loaded that remembers what affinities you want assigned to what program, so you can dump most or all processes to one core.

IIRC, there's a program out there called ROPE that would fit the bill.

I think Toms Hardware had a small utility to do this as well

edit odd double post

i think he's talking about this thread

Can someone give me a link to a CPU Affinity program as well? I'm getting a new Dual-Core CPU and I'd like to know how to get better performance.

I'll search that out and compare it.

There is a couple listed in page 2 of that other thread, I don't know if they are still online. I will have to try them out.

well let us know what you find. this thread has piqued my interest on such a program.

Well the start affinity program I can't seem to get working.

The THG one I can, but it only allows you to change applications, not background tasks. However it does allow you to save profiles, but I am yet to use that function.

Windows task manager does allow you to change the affinity of some background tasks, but not all.

I really wanted to dump everything onto core 0 and run a game on core 1.

I just finished mading a program for me that will automatically Turn CoolAndQuiet On or Off in WinXP. Mainly it just changes the Power Profile to Desktp or to Minimal Power Management to Turn C&Q On and Off. Can be controled from the system tray.

I guess I could look into making something to change Program affinitys. Scan all open processes and you can choose the process you want to change the affinity to or something?? I may look more into this and see what features should be present and such.

I'm not sure if you can control all processes as even Windows Task Manager won't allow me to set the affinities of certain tasks - mainly Windows backgound tasks like svchost.

One copy of svchost running takes 17-21 megs of RAM and has 75 threads.

If the task manager can't do it then I don't know what can...
