simulation performance but GPUs are also a promising technology with
an attractive performance/cost ratio.

+Conceptually a MAS\index{multi-agent system} is a distributed system
as it favors the definition and description of large sets of
individuals, the agents, that can be run in parallel. As a large set
of agents could have the same behavior, a Single Instruction Multiple
algorithm which illustrates the case of agents with a simple behavior
and few synchronization problems.
