Simulation Baking Questions

I’m new to baking simulations and currently working on a tutorial that I have questions about:

  1. What part of the computer is doing the actual baking? Rather, what in my computer could I upgrade to make the baking process go faster? (ie RAM, CPU, Video Card, etc)

  2. Is it possible to bake a simulation across multiple computers, like the network renderer? Or any other tricks to make the baking process go faster?

  3. Are you able to stop a bake, close or shutdown the computer, reopen the computer and Blender, and continue where you left off?

Thanks for any advice. I’m currently using Blender 2.57b with Ubuntu 11.04.
