The documentation for the ProgramControl object states that some portions of EnergyPlus are able to use more than one processor. So firstly, which portions of the code are able to take advantage of this?

And secondly, what types of models are likely to run faster when the Number of Threads Allowed field is set to 0 to use all threads rather set to run on a single thread? Do models with more or less complex geometry benefit? More or less complex HVAC systems? Specific objects or combinations of objects?
