ABSTRACT
This chapter explores an energy-efficient and high-performance solution to simulation of confrontation operations involving large crowds. Crowd modeling and simulation (M & S) has recently been gaining tremendous momentum The chapter introduces the approach to M & S of a large crowd in a confrontation operation using general-purpose computing on the graphics processing unit. It provides some background knowledge and redefines notations borrowed from other disciplines. The chapter examines the overhead distribution of the simulation program. A human crowd is a fascinating social phenomenon in nature. A crowd of people may show a well-organized structure and become disordered animals at another point. The chapter explores a quantitative analysis of the evolution of the simulated crowds entropy in terms of degree of panic. The collective behavior of a crowd in a confrontation operation is determined by both unanticipated external stimuli and the common features of the crowd itself.
