Can Simulink Models Be Ran On A GPU?

I'm part of a group trying to speed up our code. We send out inputs to the simulink model with

simIn(i) = simIn(i).setVariable('Amplitude', pops(i, 1));

simIn(i) = simIn(i).setVariable('Freq', pops(i, 2));

simIn(i) = simIn(i).setVariable('PW', pops(i, 3));

simIn(i) = simIn(i).setVariable('Ramp_Toggle', pops(i, 4));

simIn(i) = simIn(i).setVariable('Ramp_Slope', pops(i, 5));

simIn(i) = simIn(i).setVariable('Ramp_Flat', pops(i, 6));

simIn(i) = simIn(i).setVariable('Intraburst_Toggle', pops(i, 7));

simIn(i) = simIn(i).setVariable('Intraburst_Period', pops(i, 8));

simIn(i) = simIn(i).setVariable('Intraburst_Packet', pops(i, 9));

simIn(i) = simIn(i).setVariable('Phasic', pops(i, 10));

and take back outputs with

simOut = parsim(simIn, 'ShowSimulationManager', 'off');

Using tic toc it seems that the simulink model takes about 90% of our runtime. Is there a way to run this on the GPU or other ways to speed it up? Any help will be greatly appreciated.

Thank you

Hi,

You can use GPU Coder to speed up the execution of your Simulink model by using NVIDIA GPUs:

Please note that not all functions are supported by GPU Coder.

It is currently not possible to run a simulation on a GPU. The developers are aware of this enhancement request and might add this feature in a future release.

Hope it helps!

hello

is it possible to run a simulation on a gpu now?
