Box2D Forums

I was wondering how much box2d would benefit from parallel computing, especially after I ran into this http://code.google.com/p/javacl/. (click on the Particle Test Demo to see a web applet manage 1Million particles. You need a fairly new GPU).
Just wondering...

The way this engine is set up, it would be a little bit tricky to turn it into a multi-thread machine. Sometime in the future a multithreaded version of JBox2d might be made, I know ewjordan was thinking about it, but nothing (that i know of) was ever tried.

short answer, I don't see box2d doing too much with parallel computing as it was built as a single threaded engine, and all that parallel computing would do is add a whole bunch of synchronization issues.

But definitely cool, and something to ponder about.....maybe one could split up the collision detection and the solver....or do something with having a thread specifically for island and contact point resolution...hmm
