{HVY-E}Jinxx Wrote:Well, I finally finished testing that program today...

While it's made for server administrators to run programs remotely, it is capable of running programs locally and assigning processors to each program through a command line interface.

All that is required is to alter the shortcut for a particular program to reference the PsExec program and then the arguments after it to select the appropriate program and core.

S!

Thanks, Jinxx, that's great news! Big Grin

Re: Processor Affinity Explained - {HVY-E}Jinxx - 18.08.2010

Rad,

Can you pls post the RTS section of your Conf.ini so I can see it?

What type of processor are you using?
How many cores does it have?

S!

Re: Processor Affinity Explained - 8FS_Bulau - 18.08.2010

Sometimes, it makes no difference. Sometimes, even if it makes a difference, it is so small that you could only see it by careful testing with FPS counter. It all depends on the particulars of your computer.

Re: Processor Affinity Explained - {HVY-E}Jinxx - 18.08.2010

NP.

Going through your Conf.ini file now.
I need to know what video card you're running.
Also need to know if you are trying to run in DX mode or OpenGL.
S!

i'm no tech guy but i think it's chipset thing or something... and i'm using DX because OpenGL looked weird

Re: Processor Affinity Explained - {HVY-E}Jinxx - 18.08.2010

What video card are you using though?

Nvidia or ATI?

i thinks it's neither i think it's Mobile Intel 965 Express Chipset Family, it's a laptop

Re: Processor Affinity Explained - Porksmuggler - 02.09.2010

Does anyone have any benchmarks comparing the affinity settings?

Porksmuggler Wrote:Does anyone have any benchmarks comparing the affinity settings?

Hi,

A top FPS increase of about 15 or more was seen in my system just by switching the Process Affinity from the first core to the second core. I have a Dual Core system.

Re: Processor Affinity Explained - Porksmuggler - 03.09.2010

I do a lot of benchmarking, and the reason I ask is that this affinity is counter logical to thread management of the operating system. For instance, on a new i5 or i7 series CPU, the turbo mode kicks into higher multipliers for single threaded applications. The scheduler in Windows 7 or Vista will move the single thread around to balance load and temp on the 4 cores, all the while the CPU maintains the higher CPU clock. This processor affinity would interfere with this process. This all can be tested very simply with cpu-z and prime95 running a single thread. I understand your logic for moving the IL-2 thread off a core that the operating system is using for other apps, but this is not how current Intel CPUs with Windows 7 or Vista work in practice.

Hi, Porksmuggler

Isn't it true that the system can always over ride the Process Affinity as the system decides that it is needed? Factors such as those written by you can cause the system to place processing where needed. From what I have read, the re-allocation of processing as needed is the case in every system.

Porksmuggler,

Try D/Ling this program http://technet.microsoft.com/en-us/sysi ... 97553.aspx. It will allow you to allocate cores at the startup of the program. You can setup every program that you use to run on a specific core.

S!

Re: Processor Affinity Explained - Fireskull - 04.09.2010

Thank you, Jinxx Smile

Can you post the link to the core program in the first post and a brief explanation?
