Windows Multi-core Curiosity

[lilshatespug217]

From my research on the subject so far (I was bored and decided to learn about how different oses handle programs) it looks like windows, unlike mac and linux which spread the OS and program loads across all cores more or less evenly, puts the os on only one core, and assignes each program to it's own core, if possible. If this is the case, how do multi-core optimised applications work on windows? (This is purely based off of curiosity.)

You shure windows puts OS on only one core? It seems like it spreads it evenly.

I think it runs on more than 1 core. That part was easy to test. Flying though pictures used 4/8 cores. Multicore programs work they way you would think they do.....run on however many cores it was programmed to do.

 

Each program is not assigned its own core. They are assigned to different cores with programs sometimes running on the same core. If what you said was the case, then you can only run as many programs as you have cores which makes no sense. 

 

Part of what you said makes me question too why some programs aren't programmed to use all cores. Mostly games. I know part of it is that if you use less you can get more power from those fewer cores. I read that somewhere a long time ago.

Its more towards, multithreaded applications, not assigning each program to its own core. The PS3 processor had the os assigned to the PPE(Power Processing Elements) which then distributed the processes to its other 7 cores.
