AMD 64 X2 Processor: Any what to tell what program/process is assigned to processor?
Or does the core logic split some programs/processes between two processor?

Canuck For single threaded programs under Windows XP pro for example the OS balances the work load between the 2 cores unless the cpu affinity is set to CPU0 or CPU1. In windows xp pro task manager, select a running exe like "notepad.exe", right click , select affinity. EdG Yeah, I rarely have to touch affinity even on my older dual-CPU board. XP does a decent enough job of handling the scheduling. I just wrote a small program to auto set the affinity, like madden 05 doesn't like a dual core, but I didn't install any of the dual core hot-fixes or patches either, so who knows. ;p You should never have to set a processor affinity, the OS should be able to handle that. Install the OS patches and then see if you still have any problems. |

You rarely have any "need" to set processor affinity, but you can sometimes increase performance by doing so with specific applications. -- "Gee, Bill what do you want to do tonight?"

wrote: If you choose the affinity for an intensive app, will it result in higher overall cpu temps? Short answer, no. Ultimately, regardless of affinity, the same amount of work needs to be done and that will generate the same amount of heat. Windows will tend to load processors roughly evenly, give or take, so this will tend to keep the temperatures roughly even. If you for processes to one or the other CPU (or core), you may result in one or the other working harder and generating more heat, but the other will generate less heat. From a case cooling point of view, it's all the same. From a CPU cooling point of view, if your cooling isn't adequate to handle 100% load for an extended period of time, you've got bigger problems. -- "Gee, Bill what do you want to do tonight?"

"The Frozen Canuck" writes:

How to determine what is running on a given CPU is operating system specific, and you didn't specify your OS. If a program/process is multithreaded, two threads may execute simultaneously. scott |
