MATLAB: Parfor error after compiled

compilerparallel computingparfor

I am testing parfor using a simple code as below

— matlabpool open 2; parfor i = 1:10 display(i); end matlabpool close;

It does not work after compiled and gives the following error. Does anyone have an idea on this? Thanks for your help

— Starting matlabpool using the 'local' configuration … connected to 2 labs. ??? The class "distcomp.remoteparfor" is undefined. Perhaps Java is not running.

Error in ==> parallel_function at 430

Error in ==> Untitled at 3

MATLAB:subscripting:undefinedClass

What is the command line you are using to launch the application?

Can you validate the local configuration successfully (Parallel > Manage Configurations > select local > validate)

If you run the code in MATLAB, does it work?

MATLAB: Parfor errors when file is compiled

This type of error occurs if you are attempting to compile a script instead of a function. Try changing your code to:

function myParforTest
  try
    if(isdeployed)
        matfile = 'local.mat'; % can also use uigetfile to let
        setmcruserdata('ParallelConfigurationFile',matfile);
    end
  if (matlabpool('size') > 0)==1 %cerrar matlabpool si está abierto
    matlabpool close
  end
  matlabpool open 2;
  parfor i=1:10
  end
  matlabpool close;
  uiwait(msgbox('Success'))
  catch ME
    uiwait(msgbox(ME.message))
  end
end

Also, make sure that the local.mat file is included in the CTF archive (-a option if using mcc).

MATLAB: Trying to get executable to use other computer’s multiple cores with matlabpool, but getting error

Solved the problem. Turns out I needed to make my code a function before compiling it into an executable. I simply added

function testcode
at the top of my code.

This got rid of the

Error in ==> parallel_function at 430

Hope this helps out.
