If I run separate instances of Simulink, will set_param affect all instances?

When I use set_param to change a parameter, is the change local to that instance of the model, or is the changed value in effect if I open another concurrent instance of the model? I run parameter studies from a Matlab script which loads the Simulink model with load_system, changes a gain with set_param, but doesn't subsequenly save the changed model. To speed up the study completion, I start 4 instances of Matlab on my 4-core machine and run a separate instance of the script in each Matlab session. I want to make sure that changes with set_param are local and would not affect the other concurrent instances of the model.

As long as you don't save the changes to the model, it shouldn't affect any concurrent sessions.

I can't say with any certainty, but I wouldn't expect it to. I highly recommend that you check it!
Open two ML sessions, run it with the exact same configuration you are planning on using, and check the parameters in both sessions after.
