Abstract
The Social Distances (SD) model for massive evacuation is based on a Cellular Automata and agent-based representation of pedestrians. When parallel processors are used, this approach creates a high performance simulation. In this paper, we present a new algorithm for Social Distance that is highly optimized for GPU computations. The original algorithms were redesigned in order to efficiently exploit the power of graphics processors. The performance of the SD model executed on a GPU is several times greater than the performance of the same algorithm executed on a normal CPU. It is now possible to simulate at least \(10^{6}\) pedestrians in real time.
