Matlab/Simulink: run batch of simulations in parallel?

I have to run a series of simulations and save the results. Since by default Matlab only uses one core, I wonder if it is possible to open multiple worker tasks and assign different simulation runs to them?

I aso have the same problem but I did not manage to really understand how to make it in MatLab. The documentation in matlab is too advanced to get to know how to make it.

Since I am working with Ubuntu I find a way to do the work calling the unix command from MatLab and using the parallel GNU command

So I mange to run my simulation in parallel with 4 cores.

unix('parallel --progress -j4 flow > /dev/null :::: Pool.txt','-echo')

you can find more info in the link Shell, run four processes parallel

Details of the syntaxis can be found at https://www.gnu.org/software/parallel/ but breifly I can tell you

--progress shows a status of the progress

-j4 tells the amount or jobs in parallel you want to have

flow is the name of my simulator

/dev/null was just to avoid the screen run output of the simulator to show up

Pool.txt is a file I made with the required simulator input that is basically the path and the main simulator file.

echo I do not remember now what was it for :D

You could run each simulation in a separate MATLAB instance and let the OS handle the process to core assignment.

One master MATLAB could synchronize each child instances checking for example if simulation results file are existing.
