RE: [EnergyPlus_Support] Multi-threading EnergyPlus

["Crawley, Drury" <Drury.Crawley@xxxxxxxxxx>]

EnergyPlus only runs a single thread--no multithreading (yet).
 
But I recently went from a single core 1.8 GHz machine (with 1 GB
memory) to a dual-core 1.2 GHz PC (with 2 GB memory).  The set of
example files ran almost twice as fast on the new dual-core PC.  Two
reasons--the extra memory and the unloaded second core.

I believe that NREL is running E+ on clusters.
