MATLAB: Issue with Simulink Model Simulation inside Parfor

Parallel Computing Toolboxparforsimulink

Hi,
I am trying to run multiple simulations with different data set on model 'ModelTest.slx' using parfor.
my code goes like this,
parfor
 simout=sim(bdroot,<options>)
 ..
 ..
 ..
end
Parfor executes one simulation (sometime it runs two simulations). It geerates 'slprj' folder after first simulation.
Then it gets aborted with following error message.
"C:\Users\…\parllelTest\slprj\_jitprj\jitEngineAccessInfo.mat.
Not a binary MAT-file. Try LOAD -ASCII to read as text."
Below are the details of matlab version and model settings,
Matalb 2015b,
parpool with local profile.
Simulation Mode : Normal;
Solver :Fixed Step, discrete
Does anyone have any idea about this error. ?

As @Sean says, parsim is the way to go if you can. However, as a workaround, you might get away with doing something like this:
parfor idx = ...
    oldFolder = cd(getAttachedFilesFolder());
    sim(..);
    cd(oldFolder);
end
This puts each worker into a unique working directory, which might well get around the problems with the Stateflow compilation results overwriting each other.
