Interest-based distributed simulation system

A distributed simulation system for performing a simulation comprising a plurality of components, the system comprising:

• multiple servers, wherein a component-server deployment defines which server is tasked with processing each component of the simulation;
• a central 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 a server of the multiple servers is authoritative over a target component of the plurality of components of the simulation;
• wherein said central 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 central database based on the inverse interest list.

A non-transitory computer readable medium retaining program instructions for implementing a method in a distributed simulation system for performing a simulation composed of a plurality of components, wherein the distributed simulation system comprising multiple servers and a central database, wherein each server of the multiple servers is tasked with processing a portion of the plurality of components of the simulation, wherein the central database is tasked with storing values of components and delivering the values or portion thereof to one or more servers based on interest definitions, wherein the program instructions are configured, when read, to cause a processor to perform:

• 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 central database, whereby reducing bandwidth utilization between the server and the central 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.
