Ray-tracing is a classic example of an embarrassingly parallel algorithm; since each pixel is typically independent of the rest, theoretically every pixel can be done in parallel (given enough core
The N-Body problem is a classic example used frequently to demonstrate parallelization and how it improves performance.
Particle systems are an ideal candidate for multi-threading in games. Most games have particle systems and their general nature of independent entities lends well to parallelism.
