High-Level architecture (HLA) is an architecture for distributed computer simulation systems. Using HLA, computer simulations can interact with other computer simulations in a cross-platform manner. The interaction between simulations is managed by a Run-Time Infrastructure (RTI). HLA is an IEEE interoperability standard for distributed simulation.

High-Level Architecture (HLA) is a general purpose architecture for distributed computer simulation systems.

Using HLA, computer simulations can interact with other computer simulations in a cross-platform manner.

The interaction between simulations is managed by a Run-Time Infrastructure (RTI).

HLA is an IEEE interoperability standard for distributed simulation used to support analysis, engineering and training in a number of different domains.

HLA - usage of timeAdvanceRequest()

I have HLA simulation in Java using pRTI with two federates. I want to advance time of my simulation. As far I know, following method is used for this purpose: _ambassador.timeAdvanceRequest(time); , where ambassador is an RTI ambassador. My…

Do I use provided time or user supplied tag when handling a reflect on a receive order attribute from a time managed federate?

In a simulation using RPR-FOM, if I get a reflectAttributeValues with a LogicalTime time stamp (simulation time) and the OrderType receive order in my FederateAmbassador. For dead reckoning algorithms do I use the time stamp supplied by the RTI or…

How to know if a federate has joined a federation in HLA

I am using HLA and the Portico RTI and I have a situation in which I have to know that if particular federates have joined the federation or not. Can someone help with this. This may be very basic but i am very new to HLA. Thanks in advance.

How can I correctly update an instance of a Federate?

I am using Pitch pRTI free and "World Map" simulator. I tried by looking at page 50 of "The HLA Tutorial.pdf" to set and update for a federate instance, but I am failing in it, I don't know why. In advance, the object in my code is instantiated and…

HLA: FOM vs SOM

I'm starting to study how to implement HLA in a project that I'm developing, and there's something that I can't understand very well. In a federation, the data that are exchanged are defined in the FOM (Federation Object Model), that contains all…
