High-Level Architecture (HLA) is a general purpose architecture for distributed computer simulation systems.
Rather than have the entire simulation within a single executable, the simulation is split into different Federates, which interact with each other by a Run-Time Infrastructure (RTI).
There are three big advantages to this over a monolithic simulation (e.g. FlightGear V3.6):
- It provides a robust environment to make the simulator multi-threaded, taking advantage of computers with multiple cores, or indeed running different parts of the simulation on different computers.
- It allows us to split out parts of the simulator such as the FDM and Renderer from each other and less time-critical sub-systems such as weather so that we can get consistent (and perhaps higher) frame-rates.
- It provides a very good framework to allow anyone to create components that interact with FlightGear.
Stuart has started work on re-architecting FlightGear to use HLA, though this is expected to be a multi-year project. Anyone interested in the current status of development should subscribe to the Flightgear -devel mailing list.
