Using Parallel Toolbox, Matlab Exit Status: 0x00000001

[Vahila]

Hello,

i have several Unittests and at least one of them checks if everything works properly using the parallel toolbox. The test is not failing after all, but Jenkins returns "ERROR: MATLAB error Exit Status: 0x00000001". The reports itself tell me that the test went sucessfull, so it must happen somehow after the test. I could also narrow down the problem to this one test, because i started to deactivate all other tests until only the ones with the parallel toolbox were left.

I assume that Jenkins just kills the process, because the window of the simulation manager closes on it's own, maybe this has to do with the problem. Do you have an idea how to solve this problem? I'm shutting down the pool within the script, so i'm not sure what exactly the problem is.

Thanks!
Adrian

Starting parallel pool (parpool) using the 'local' profile ...
Preserving jobs with IDs: 1 2 3 4 5 6 7 because they contain crash dump files.
You can use 'delete(myCluster.Jobs)' to remove all jobs created with profile local. To create 'myCluster' use 'myCluster = parcluster('local')'.
Connected to the parallel pool (number of workers: 6).

The error happens when the Simulation Manager window opens during the unit test, passing to the parsim "'ShowSimulationManager', 'off'" solves the problem.

Is this a problem that is known when doing unit tests that include GUI elements or is it a problem exclusively with the Simulation Manager?
