High level architecture (simulation) DefenseSpaceAir Traffic ManagementEnergyOff-shoreRailway and car industryManufacturingHealth care A high-level architecture consists of the following components: Federate: an HLA compliant simulation entity.Federation: multiple simulation entities connected via the RTI using a common OMT.Object: a collection of related data sent between simulations.Attribute: data field of an object.Interaction: event sent between simulation entities.Parameter: data field of an interaction.
Much of the interactions between federates involve objects and interactions which work in a publish-subscribe model. A federate can register an instance of an object and then change the attributes. Other federates that are subscribed to the object receive attribute value updates. The interface specification is divided into service groups: The object model template (OMT) provides a common framework for the communication between HLA simulations. Federation object model (FOM). HLA is defined under IEEE Standard 1516: Distributed Interactive Simulation.
Distributed Interactive Simulation (DIS) is an IEEE standard for conducting real-time platform-level wargaming across multiple host computers and is used worldwide, especially by military organizations but also by other agencies such as those involved in space exploration and medicine.
History[edit] The standard was developed over a series of "DIS Workshops" at the Interactive Networked Simulation for Training symposium, held by the University of Central Florida's Institute for Simulation and Training (IST). The standard itself is very closely patterned after the original SIMNET distributed interactive simulation protocol, developed by Bolt, Beranek and Newman (BBN) for Defense Advanced Research Project Agency (DARPA) in the early through late 1980s.
BBN introduced the concept of dead reckoning to efficiently transmit the state of battle field entities. The DIS family of standards[edit] DIS is defined under IEEE Standard 1278: Current status[edit] Application protocol[edit] Umbra Software - Umbra 3 performance optimization middleware. Telemetry Performance Visualization System. Telemetry 2, the new version of RAD Game Tools' performance visualization system, is shipping now!
Telemetry helps you optimize and understand your application's performance—unlike other traditional profilers it emphasizes performance characteristics in relationship to time and program state, whole-team participation of optimization, always-on profiling, cross-platform support, and ultrafast integration. Telemetry is a performance visualizer, so all your performance information is presented graphically—why wade through rows of numbers trying to find patterns when Telemetry can show you those patterns?! In addition to this Web page you can learn more about Telemetry by: reading what our customers think, checking out Telemetry's features, FAQ, and version history; reading the Telemetry blog; and following the Telemetry Twitter feed. Application State vs. Performance All good profilers can tell you that something took too long. What else was going on in the application? When did it happen?
