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.

This is working with sending files to workers. I have few other questions on batch program, maybe I will start a different thread for that.
Thanks for the help!

Great, glad this is working. Yes, it's best to keep different questions separate.

Have you looked at parsim? It's the new an improved means for simulating in parallel and takes care of the file management that was always a pain to do on your own.
