Cleaning parallel workers messages appears just immediately after running simulations when using parsim

I am trying to run 100 parallel simulations using parsim. If I run 4 simulations (also in parallel), it runs perfectly. However, when I decided to run 100 simulations the parpool starts normally, but right after the "Running Simulations" message appears, it mentions that it is "Cleaning up parallel workers" as if it has already finished.

I had waited hours, and not even 1 simulation has conclude.

Have you tried using Simulation Manager? Sometimes that can make it easier to see what is going on.

I'm not a Simulink user, so bare with me in case I take you down the wrong path.
I'm guessing you are setting the parsim RunInBackground option to 'on', which will display the message. Take a look at
to see if it's required or if batchsim is a better option for your workflow.
