[Algorithms] Concurrency

[Ron H. <rh...@cy...>]

I asked this on the DirectX list, but I figured this might be a 
better place for a more general discussion.

What are some good ways to make a game more concurrent as far as
the CPU and graphics card are concerned?  Is it better to send over
the primitives all in a single bunch, or to split them up into batches
and do calculations interspersed between them?  

Thanks!
