Running Multiple Digital Twins at the Same Time

The DTaaS platform allows for executing multiple Digital Twins in tandem with one another. This can save hours of time when dealing with intensive Digital Twins or when you want to deploy them across different resources.

⏯️ Running Digital Twins

When you want to deploy a Digital Twin you can do this from the Execution tab on the Digital Twin Preview page. You can find this by clicking on the Workbench icon in the sidebar on the left hand side and locating Digital Twins Preview among the other links. Click to open the Digital Twin Preview page in a new tab.

In the newly opened tab you will see a series of cards with a name, short description of the Digital Twins and START and HISTORY buttons. The START button sends a job to the backend, telling it to run the simulation associated with that Digital Twin, which is defined by its Life Cycle files. You can inspect and change these in the Edit tab.

Running Multiple Twins

Pressing the START button multiple times queues multiple simulations. You can also queue different kinds of Digital Twins.

The deployment service (e.g. GitLab) automatically load balances across available runners, so you can set it and forget it.

🗃️ The Execution Log

Pushing the HISTORY button provides an overview of all current and past simulation trials, distinguished by time of execution and status (Running, Failed, Succeeded or Timed Out). To check how a simulation went, you can click on an entry (or the arrow on the right of the entry) to expand it. Each step in the Life Cycle will then be presented.

If you want to delete an entry, click the trash icon. A verification box will reassure you that you are deleting the right one. You can also delete all entries of a Digital Twin with the CLEAR ALL button.

Click the stop symbol in the log to stop an execution:

🔧 Changing Runners

You can change which runners pick up the jobs in the settings. Read more about this and other settings that are available.

💭 Summary

You have now learned how to navigate the DevOps Execution page: execute multiple Digital Twins at the same time and inspect and delete their logs.
