Is it possible to run a complied simulink model with "rtwbuild" in parallel?

I have a complex simulink model that is complied with rtwbuild to reduce run time. I need to run optimizations and parameter sweeps. Is it possible to do so in parallel?

% RTW Build 
rtwbuild(mdlName)

% Get RTP Structure for Parameter Alteration
rtpstruct = rsimgetrtp(mdlName,'AddTunableParamInfo','on');

% Save Tunable Parameter Structure 
save('Rsim_Params','rtpstruct')

% Execution Command
runname = ['.',filesep,mdlName,...
    ' -p Rsim_Params.mat -i Rsim_Input.mat -tf ',...
    num2str(Tend),' -v '];

% System Command - Run Model 
[~,~] = system(runname);

If you have Parallel Computing Toolbox, the function parsim lets you run simulations in parallel, including in rapid accelerator mode: https://uk.mathworks.com/help/simulink/slref/parallel-simulations-using-parsim-parameter-sweep-in-rapid-accelerator-mode.html.

If you want to stay with MATLAB and Simulink, you can call system multiple times in the background by adding "&" at the end of your command. You'll want to make sure you write to different output files!

"To execute the operating system command in the background, include the trailing character, &, in the command argument."
