Hello all:
I have a Franken-Puter (a PC assembled with various parts), running a dual core Intel Pentium D 2.66GHz processor. Here's my situation: I'm wanting to run two somewhat memory-heavy programs at the same time and was wondering if I should set the core affinity for one program to core 1, and the other program to core 0, or should I let them share cores, essentially letting them "battle out" what core concentrates on what program.

I hope this makes sense. I'm an intermediate computer user, so I'm not sure of my terminology.

Any help/suggestions/advice would be much appreciated.

Kind Regards,
Daniel in Tulsa

I'd suggest letting the programs negotiate for use of the processors. But, if you're in an experimental mood - try the program with and without setting the core affinities - that way you can tell which seems better to you. You don't need no fancy testing tools for this - just a bit of patience to try each one thoroughly before deciding. If you can't tell a difference, then it really doesn't matter! :thumbsup:

Hi siouxdax.

Task Manager has the ability to display core (aka CPU) usage for dual core PCs. Just click the Performance tab. Well, it works for my AM2 dual core.

Yes, I understand how to view core information as well as how to set affinity. I think you need to re-read my original post.
