How do I program a game for multicores?

[KPC84]

Is there a website or something where you can download a patch to make a game run with 2 or 4 cores? If most games right now don't come from the factory with that already built in, then getting a quadcore is a waste of money right now. I'm so confused. And for that matter, what about running in SLI config....Does a game have to be "told" to run in SLI or does it just happen?

Thanks.

has to be told

the programming needs to be split into multiple processes at it's source, the only multi-core processor that's available to date that can automatically teach itself how to run a single-process program on multiple cores is the cell processor.

Ok, so how do I "tell" a game to run in multicore fashion?

You can't. It's like trying to tell a car to split in half, have half drive in the first lane and the other half in the 3rd lane. A game needs to be coded from the bottom up to work on multiple cores. Only the coder/programmer is able to do it.

A waste of money ? it depends on how you look at it . your game can run in " one core " and say TS/Vent, IE or other applications in another so you will gain some performance.
