Original Kurzfassung:
Understanding the dynamics of urban evacuation systems -due to
catastrophic disasters induced by forces of nature like flooding
or tsunamis, terrorism or nuclear power plant accidents- has
elicited massive interest over the past years. While discrete
event simulations of evacuation models become prohibitively
complex dealing with the time, space and individual behavior,
multiagent based models have revealed to be a potentially more
effective. This paper introduces models of configurations of
social agents at a massive scale, which, together with the most
recent supercomputing technology allows for a simulation analysis
of realistic evacuation models at the level of large cities
(10^6-10^8). Agent based models of demographics and the
morphology of cities together with population densities, mobility
patterns, individual decision making and agent interactions are
implemented into a tool chain which ultimately generates Repast
HPC code, which is then executed on 2048 node shared memory
multiprocessor (SGI Altix Ultra Violet 1000).
We demonstrate how
different evacuation strategies can be assessed based on costly,
yet feasible simulation runs - thus evidencing, that a whole
class of demanding, very complex simulation problems has found a
convincing solution.
