What is the best way to exploit multicores when making multithread games?

Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses…

When does a parallel-tasks engine becomes a good solution?

I'm often tempted to break the game I'm working on to try a parallel-tasks based architecture, but that don't seem a big requirement for my project so I avoid this for the moment. I'm planning to just try it in a toy project first, to "play with the…

I have been reading a lot about this, but still not sure about a proper way to implement an independent render thread, using a variable time step and running in parallel to a physics thread, which uses a smaller, fixed time step. I'm familiar with…

Implementations of task-based parallelism in game engines_

I'm looking for implementations of this because I'm having an especially hard time understanding how data is usually handled. As I understand it, simply using critical sections and locking code regions where modification of shared resources happens…
