Simulation systems using an inverse interest list

A distributed simulation system for performing a simulation of a simulated world, wherein the simulation is performed by simulating values of a plurality of components representing a state of the simulated world, the system comprising:

• multiple servers, wherein a component-server deployment defines which server is tasked with processing each component of the simulation to compute a value thereof;
• a database for storing values of components and delivering the values or portion thereof to one or more servers based on interest definitions, wherein the interest definitions establish which values are needed by which server for processing values of respective tasked components, wherein the database is configured to deliver simulated values computed during the simulation by one server to a second server to allow the second server to compute other simulated values for determining the state of the simulated world;
• wherein a server of the multiple servers is authoritative over a target component of the plurality of components of the simulation;
• wherein said database is configured to determine an inverse interest list for said server of the multiple servers, wherein the inverse interest list identifies all servers requiring the target component to compute their components tasked thereto;
• and
• wherein said server of the multiple servers is configured to selectively transmit updates of the target component to the database based on the inverse interest list.

• processing of a target component by the server, whereby setting a new value to the target component, wherein the target component is comprised by the plurality of components of the simulation, wherein the server is comprised by the multiple servers;
• and
• determining, based on interest definitions of other components that are processed by other servers, to avoid providing an immediate update of the new value to the database, whereby reducing bandwidth utilization between the server and the database, wherein said determining is based on an inverse interest list, wherein the inverse interest list comprises an identification of components whose values are calculated based on the target component, wherein said determining is further based on a determination whether a value of any of the components in the inverse interest list is computed by another server other than the server.
