Abstract:
1. A distributed simulation system comprising: a plurality of nodes, wherein each node of the plurality of nodes comprises a simulator and is configured to simulate a different component of a system under test using the simulator, and wherein each node is configured to perform a simulation as a series of timesteps, wherein a timestep is a granule of simulation time by which the simulator evaluates events and advances the simulation of the component, and wherein a simulation of the system under test comprises the plurality of nodes simulating the components, and wherein each node is configured to transmit a first command indicating that the node has completed simulation for a first timestep and thus that the node is capable of completing the first timestep; wherein a synchronized transition from the first timestep to a second timestep that follows the first timestep in the plurality of nodes is performed responsive to receiving the first command from each node of the plurality of nodes.
