As above, can a compiled MATLAB standalone application (.exe) coded with parfor loop, make use of MATLAB Distributed Computing Server workers?

If yes, how do i configure the application to do so? Thanks!

在 MATLAB Online 中打开

Since R2008b applications deployed using the MATLAB compiler can access a cluster running MATLAB Distributed Computing Server.

The documentation has information and examples: http://www.mathworks.com/help/toolbox/compiler/f12-999353.html#br2jauc-47, but a quick example might look like this

function my_compiled_app
    % Open a matlabpool on the cluster defined
    % by the 'my_cluster' configuration
    matlabpool('open', 4, 'my_cluster');
    % Run a parfor loop on the cluster
    parfor i = 1:10
       disp(i)
    end
    % Close the pool   
    matlabpool('close');
  end

Compile the application using mcc

>> mcc -m my_compiled_app

And the run it - this should open a matlabpool on the cluster, and show the parfor running

C:\Work> my_compiled_app.exe

I know of customers that somehow distribute MATLAB Compiler generated EXEs on their clusters. However, I do not think this can be done using MATLAB Distributed Computing Server. The question is why would somebody who has MATLAB and MDCS available go the detour of first creating an EXE?

The short answer to your question is code protection.

We developed models for clients who has MDCS cluster and the concern tha i have is the processing speed. If we distribute the application in exe to client and if the exe do not use the MDCS workers that the client has, then my company will be penalized.
