Taking advantage of dual core processors!!!

Teletubby · 08-17-2006, 09:14 PM

Is it possible to make a program utilize BOTH processor cores on a dual core processor???

Here is my processor:

CPU 1/1
Intel(R) Pentium(R) D CPU 2.80GHz
Manufacturer Intel
Family Intel(R) Pentium(R) D CPU 2.80GHz
Architecture 64-bit
Internal Clock 2.8 GHz
Internal Clock Maximum 3.8 GHz
External Clock 200.0 MHz
Socket Designation Socket 775
Upgrade ZIF Socket
HyperThreadingTechnology Available - 2 Logical Processors
Capabilities MMX, CMov, RDTSC, SSE, SSE2, PAE, NX
Version Intel(R) Pentium(R) D CPU 2.80GHz
Caches
Level 1 16 KB
Level 1 16 KB
Level 2 2 MB

and btw I got 2 gigs of RAM

I know how to change the affinity thing on the windows task manager, but I dont know if the program actually USES the two cores, cuz changing the affinity only ALLOWS it to use both cores. Is there any way to make a program use both processing cores, or some program that makes other programs use both cores?!?! thanks! I also was wondering if you could just simply change some coding in a program to do this. Thanks!!!!

It really isnt something you can do. You just need to find a program that can utilize both. Intel might have a driver on their site to allow for the utilization of both cores better.

I know Adobe Photoshop CS2 utilizes both cores.

cool thanks! Ill check for drivers at Intel.

You need to find multithreaded software. More of it will be coming out in the next few years

Can't you also assign different programs to different cores?

You can't assign a program to run on both unless it is multithreaded. Core affinity can be set in code but that only does so much, it's usually better to let the OS to handle load balancing.

that kinda sux...I hope they come up with a driver that will utilize both processors. That will make 5.6 ghz

or maybe even 6.4 if I overclock this baby

It's not about a driver. It is how the software is written...

If AMD's reverse hyper threading exsisted, then you could make your cpu run as a super fast single core.

That's a big if. It's insanely complicated to manage that, and assuming someone could make a design that could, I doubt it would have much performance bonus. The management overhead would be tremendous.
