[EnergyPlus_Support] Re: Multiple instances of EnergyPlus Running at the same time.
Would Energy+ be eligible to run under CUDA, or any other parallel architecture?
Stating Wikipedia, "CUDA (an acronym for Compute Unified Device Architecture) is a parallel computing architecture developed by NVIDIA. CUDA is the computing engine in NVIDIA graphics processing units or GPUs that is accessible to software developers through industry standard programming languages."
I read about numerous projects, especially CFD calcs which seems to gain much from this on processing time. Also, some libraries "Fortran like" exist, so that Fortran users can easily migrate their code.

I have an 8-core computer and want to take advantage of it. I'll post the first part of it if anybody is interested.
