Why multiple instance of a component that has export function(client server interface) is not possible?

My client server interface uses sender receiver port in its calculation. These server functions can be called from different cores. Therefore I wanted to make these functions which uses sender receiver port as mulitple instance compatible. But this is not supported in simulink.

How to solve this?

Hi Jeevan,

I understand from your query that you want to use a function that is compatible with multiple instances in Simulink.

Simulink follows a single-threaded execution model. To work with multiple instances, MATLAB System block or Simulink Function block can be used along with Model Referencing. Model Referencing allows you to create reusable components and reference them multiple times. You can find more information about them in the documentation below:

• MATLAB System block - https://www.mathworks.com/help/releases/R2023a/simulink/slref/matlabsystem.html
• Simulink Function block - https://www.mathworks.com/help/releases/R2023a/simulink/slref/simulinkfunction.html
• Model References - https://www.mathworks.com/help/releases/R2023a/simulink/model-reference.html

Here is an example that shows how to use multiply instanced Simulink Functions:

If the components can be parallelized, MATLAB’s Parallel Computing Toolbox can also be used. You can learn more about it from the documentation below:

Hope this helps.
