Abstract: Disclosed herein are a node search apparatus and method. The apparatus includes a communication unit, a node search execution unit, and publish-subscribe communication middleware. The communication unit receives information about a child node of a root node in a node tree and a target node from a task distribution unit. The node search execution unit performs a search for the target node on the child node and the lower nodes of the child node. The publish-subscribe communication middleware publishes information about a visited node, which belongs to the child node and the lower nodes of the child node and which is determined not to correspond to the target node by the node search execution unit, to a global database.

Abstract: Disclosed herein are an apparatus and method of performing distributed simulation. In the method of performing distributed simulation, a simulation time provision apparatus sets global simulation times synchronized with real times based on the real times. The simulation time provision apparatus distributes the set global simulation times over distributed simulators. Each of the distributed simulators adjusts the interval between local simulation times, during which the continuous or discrete elements of an allocated one of subsystem models that model subsystems forming a hybrid system will be analyzed, based on the global simulation times. The distributed simulator performs simulation to analyze the continuous or discrete elements of the subsystem model during a period corresponding to the adjusted interval between the local simulation times.
