Intel Multi-Core Game Demo

[maroon1]

This is the binary and source of a demo we created to show how games can take advantage of multi-core processors. It's dead simple - you control a cannon facing down a terrifying, lethal... castle. Knock it down, put it back up and then knock it down again!

First shown at GDC 2006, we are continuing to improve the code to keep pace with our latest processors. Now you can download the demo and the source code to see techniques that you can use in your own game projects.

Cool find, cheers! There's a big difference between single and multi core.

 

[Kornowski]

I don't get what it does, does it just utilize both cores?

 

[PabloTeK]

Yep, I have noticed one thing, in multi core mode the building collapses slower but the FPS increases!

 

[Kornowski]

Is multi core mode, multi thread, I guess, so if you have it on singe-threaded it's using on core?

It's cool, but like GCR said, the building collapses rather slow...

What esle can you turn on to make it dual core... anything other than pressing 'T'?

Nice find maroon1 Thanks

EDIT: Just noticed the bugs are easier to squash in single thread mode and they don't in multi-thread...

 

[Kornowski]

I noticed something else, also, If you pause the AI, the cannon balls and the building go at the correct speed... How to do turn the AI thread thingy on, it's blue at the top?

Click "T" to switch between single-threaded and multi-threaded modes
Click "I" to cycle through allocating between 1 and 4 threads to AI processing

Note: Maximum use of a single-core system is achieved with multi-threading turned off (the default). Maximum use of a two-core system is made with multi-threading on and AI Data Decomposition off. Maximum use of a four-core system is made with multi-threading on and AI Data Decomposition set to 2 threads.
