Threading Successes of Popular PC Games and

Engines

22

What did we cover?

•Thread for performance– Supreme Commander– Gamebryo Element Engine

•Thread for features– Hellgate: London– Intel’s n-core experiment

•Use threaded middleware– Allegorithmic’s Substance

33

What should I avoid?

•Don’t– Get seduced by terminology– Use complexity rather than concurrency as your

measure of success– Design for specific numbers of cores, or rely upon

symmetry of cores– Freak out; nobody has cracked the problem yet

and forgotten to tell you

44

What should I do?

•Do– Use threaded middleware to ease your design

efforts– Use a multi-threaded memory management

scheme– Put task parallel and data parallel tasks into the

same thread pool– Tell us about your progress and any problems

you’re having
