Loading Model on Parallel Workers

I am trying to run a parsim of my Simulink model, varying the value of a resistor. The script seems to get the stage "Loading Model on Parallel Workers" however does not progress any further. My code is shown below.

model = 'ElectricalModel';
open_system(model,'loadonly');

resistances = linspace(100,110,2);
numSims = length(resistances);
simIn(1:numSims) = Simulink.SimulationInput(model);


for i = 1:numSims   
   simIn(i) = simIn(i).setBlockParameter([model '/Resistor'],'R',num2str(resistances(i)));
end

out = parsim(simIn, 'ShowProgress', 'on','ShowSimulationManager','on');

The script seems to be stuck in this while loop which is part of the JavaBackedFuture.m file.

while ~predicate(obj) && ~deadlineExpired
    millisToWait    = min(waitGranularity, iGetMillisRemaining(deadline));
    deadlineExpired = (millisToWait == 0);
    javaTask.await(millisToWait, millisUnit);
    if ~predicate(obj)
        iJavaLog(4, 'parallel.Future waiting for ID: %d', obj.ID);
        % Ensure wait() is re-entrant by incorporating a drawnow.
        drawnow();
    end
end

Any suggestions would be greatly appreciated.

Hi Rob,

Can you please confirm if your system has enough memory for all the parallel workers? The only thing I can think of is that the system is running low on memory and has started to page the memory which can make processing extremely slow.
