Parallel Computing in Optimization Toolbox

I want to use the GA toolbox for optimization but with the parallel option ('UseParallel', true).
options = optimoptions(@ga,'Display', 'iter', ...
'OutputFcn',@GA_OUTPUT ,...
'PlotFcn', {@gaplotbestf, @PLOT_FUNCTION},...
'MaxGenerations', 60, ...
'PopulationSize', POPULATION_SIZE, ...
'FunctionTolerance',1e-6, ...
'CrossoverFraction', 0.95, ...
'EliteCount', 0.1*30,...
'UseParallel', true) ;
[x,fval,exitflag,output,population,scores] = ...
ga(@OBJECTIVE_FUNCTION,nvars,A,b,Aeq,beq,lb,ub,@POWER_CONSTRAINT,IntCon,options) ;
My question is how can I attach my working directory (/home/user/workidir) with the files to be used by the algorithm in each Worker.
Thanks.

Hi Yrobel,
A couple of quick questions first:
  1. Are you calling parpool or batch to run your code?
  2. Are you running MATLAB on the machine that's going to run the parallel code? That is, are you running MATLAB on the machine that already has /home/user/workidir mounted on it? Or are you running MATLAB on a different machine?

Hi, thanks for your reply,
  1. No, Matlab starts the parallel calculation automatically.
  2. Yes, it is the PC that I use and that is the directory where I am running the code.
Thanks.
