4 Interactive Parallel Computation with pmode

pmode Limitations and Unexpected Results
Using Graphics in pmode
Displaying a GUI
The workers that run the tasks of a communicating job are MATLAB sessions without
displays. As a result, these workers cannot display graphical tools and so you cannot do
things like plotting from within pmode. The general approach to accomplish something
graphical is to transfer the data into the workspace of the MATLAB client using
pmode lab2client var labindex
Then use the graphical tool on the MATLAB client.
Using Simulink Software
Because the workers running a pmode job do not have displays, you cannot use Simulink
software to edit diagrams or to perform interactive simulation from within pmode. If
you type simulink at the pmode prompt, the Simulink Library Browser opens in the
background on the workers and is not visible.
You can use the sim command to perform noninteractive simulations in parallel. If
you edit your model in the MATLAB client outside of pmode, you must save the model
before accessing it in the workers via pmode; also, if the workers had accessed the model
previously, they must close and open the model again to see the latest saved changes.
