What is Actor Framework in LabVIEW?

The Actor Framework is a software library that supports the writing of applications in which multiple VIs run independently while communicating with each other. Presented by Stephen Mercer, Senior Software Engineer for LabVIEW R&D and Allen Smith, Senior Systems Engineer.

What are Actor Frameworks?

The actor model originated in 1973. It has been used both as a framework for a theoretical understanding of computation and as the theoretical basis for several practical implementations of concurrent systems. The relationship of the model to other work is discussed in actor model and process calculi.

Why Use Actor Framework LabVIEW?

Many techniques exist for creating such applications in LabVIEW. The Actor Framework focuses on being easy to learn (relative to other possibly-more-powerful tools) while mitigating risk of deadlocks/race conditions and maximizing code reuse.

Is Akka a good framework?

As a conclusion: The actor model itself is what you should adopt first and Akka is a very reliable framework helping you to implement it with a lot of benefits you will receive along the way.

Does Google use Akka?

As an added bonus, Akka Serverless itself is built on Google Cloud. To deliver this stateful serverless cloud service on Google Cloud, Cloudstate needs a distributed durable store for messages. With the open-source Cloudstate you can use PostgreSQL or Apache Cassandra.

Does Flink use Akka?

The Flink project decided to use Akka for its underlying RPC service implementation because Akka can do most of the heavy lifting for you. Akka allows to easily implement asynchronous RPCs, supports enterprise features such as encryption and reaches a decent message throughput.

When did the actor framework come out in LabVIEW?

The Actor Framework is an Actor Model implementation that has been distributed with LabVIEW since LabVIEW 2012. To learn more about the Actor Model click here for the Wikipedia article . To learn about other community created Actor implementations see the”Other Actor Implementation Designs” section on the Actor Oriented Design Patterns page.

Which is the main VI in LabVIEW framework?

Actor Core will be the main vi that is run. This is where your Actor’s functionality happens. Save these vi’s and add them to the Framework Overrides folder in the project. Follow the following steps to be able to stop the Child Actor when Actor Core is closed.

How to create a child actor in LabVIEW?

Add the Set Get state from Parent vi to the event case. This will put the Boolean control state onto the queue of the Child Actor. The Do vi will then be called which will then run the method from within the Child Actor Class. This will then update the front panel indicator of the Child Actor. Save your project and run the Launcher vi.

Which is the latest version of actor framework?
