Handover techniques for simulation systems and methods
Methods, systems, computer-readable media, and apparatuses for performing, providing, managing, executing, and/or running a spatially-optimized simulation are presented. In one or more aspects, authority over one or more components may be changed from one worker to another worker during the simulation. The components may be configured to, for example, indicate behaviors of entities executing in the simulation. The system may determine to hand over authority over the one or more components to another worker, such as based on network and/or simulation conditions. The incumbent worker may be notified that authority will change to another worker, e.g., after a period of time. Authority over the one or more components may be assigned to the other worker, and the incumbent worker may be notified that it is no longer authoritative over the one or more components. The second worker may be notified that it is now authoritative over the one or more components.
