Create a Function for Checking Multiple Systems in Parallel

If you have a Parallel Computing Toolbox license and a multicore host machine, you can

create the following function to check multiple systems in parallel:

Create the run_configuration function as described in “Create a Function for

Checking Multiple Systems” on page 23-4.

Save the function as run_fast_configuration.m.

In the Editor, change the name of the function to run_fast_configuration.

Add another input to the run_fast_configuration function so that the inputs are

now:

SysList, numParallel

In the ModelAdvisor.run function, set 'ParallelMode' to 'On' . When you use

ModelAdvisor.run with ‘ParallelMode’ set to ‘On’, MATLAB automatically

creates a parallel pool.

SysResultObjArray = ModelAdvisor.run(SysList,'Configuration',fileName,...

'ParallelMode','On');

The function should now look like this:

function [fail, warn] = run_fast_configuration(SysList, numParallel)

%RUN_FAST_CONFIGURATION Check systems in parallel with Model Advisor

% Check systems given as input in parallel on the number of cores

% specified as input. Return number of warnings and failures.

fileName = 'slvnvdemo_mdladv_config.mat';

fail=0;

warn=0;

SysResultObjArray = ModelAdvisor.run(SysList,'Configuration',fileName,...

'ParallelMode','On');

for i=1:length(SysResultObjArray)

fail = fail + SysResultObjArray{i}.numFail;

warn = warn + SysResultObjArray{i}.numWarn;

end

Save the function.

Test the function. In the MATLAB Command Window, create a list of systems:

SysList={'sldemo_auto_climatecontrol/Heater Control',...

'sldemo_auto_climatecontrol/AC Control', 'rtwdemo_iec61508'};
