speeding up optimization problems with parallel computing

when I run the optimization example of portfolioProblem (DemoGAwPCT.m), the ".m" file is taken from "Speeding Up Optimization Problems with Parallel Computing" downloaded from http://www.mathworks.com/matlabcentral/fileexchange/, I get the following error when he arrive to the part ("%% Run on 4 Cores"):

??? Error using ==> matlabpool at 122

'speedy-4core' is not a valid configuration name.

Use [conf, allConf] = defaultParallelConfig to see all your configurations.

    %%Run on 4 Cores
    files = dir;
    files = {files(3:end).name};
    matlabpool('open','speedy-4core',4,'FileDependencies',files)
    tic;

    [portSubStd, portSubRet, portSubWts, portSubIndx] = ...
        computebestportfolioPCT(expRet,expCov,portSize,targetRet);

    garuntime = toc;

    % Report results
    fprintf('GA Run Time is: %f seconds\n',garuntime);
    matlabpool close

I have a computer with (Pentium® Dual-Core CPU T4500 @2.30GH 2.30GH). Is it for this reason I continue to get this error (I have a dual-core CPU, but I try to run the optimization problem on 4 core).
