 Simulator is written in C++ and utilizes CUDA to run in GPU. Therefore, it is possible to run a simulation within a short period of time provided that a good GPU presents. Simulator can detect all GPU cards, if there is more than one, and can distribute the task to run in parallel in multiple GPUs. This is helpful if you wan to run the simulator in HPC cluster with mutliple GPUs available in a node.
