MATLAB: Does the Job Manager running on a Windows client get started automatically when the machine is re-booted in MATLAB Distributed Computing Server 4.1 (R2009a)

MATLAB Parallel Serverrestartstart

My Job Manager is running on a Windows machine and has a few workers connected to it on a remote cluster. I need to know whether the Job Manager starts automatically when the machine re-boots or it needs to be re-started manually.

Best Answer

When the machine hosting the Job Manger is re-booted, the MDCE service along with the Job Manager is started automatically.

MATLAB: Is there a built-in function to automatically transfer the output files created by a worker to the client system as part of a job using Parallel Computing Toolbox 4.1 (R2009a)

The ability to transfer files automatically from the worker to the client system is not available in the Parallel Computing Toolbox.

To work around this issue, you can try the following:

1. Use the MOVE or COPY command as part of the FinishedFcn callback.

2. Create the files at a location which is accessible to both the workers and the client.

Below is a sample M-script for starting up 4 workers on a local machine with the MATLAB Distributed Computing Engine installed.

%%This document assumes you have successfully installed the MDCE Toolbox
%%Install the MDCE
cd([matlabroot '\toolbox\distcomp\bin'] or (matlabroot '\toolbox\parallel\bin')(R2019b & later)
!mdce install
%%Start the MDCE
!mdce start
%%Start the MDCE and prepare for Distributed processing
% If you would like to see the status of the workers as they run, please
% set this to true
STATUS = true;
% Start a Job Manager
% -name the name of the Job Manager
!startjobmanager -name my_jobmanager
% Start 4 workers using the previously defined Job Manager
% -name           name of the worker
% -jobmanager     name of the Job Manager
% -jobmanagerhost name of the machine the manager is running on
!startworker -name worker_1 -jobmanager my_jobmanager -jobmanagerhost localhost
!startworker -name worker_2 -jobmanager my_jobmanager -jobmanagerhost localhost
!startworker -name worker_3 -jobmanager my_jobmanager -jobmanagerhost localhost
!startworker -name worker_4 -jobmanager my_jobmanager -jobmanagerhost localhost
if STATUS
% Output the status of the workers as they are running
!nodestatus
end
%%Run your code
% After the above has been started, you can run your code
% When you are done running your code execute the below cells of code
% to cleanly shut down the Workers, Job Manager and MDCE
%%Stop all the Workers, Job Manager and the MDCE
cd([matlabroot '\toolbox\distcomp\bin'])
% Stop the 4 workers previously started
!stopworker -name worker_1 -jobmanager my_jobmanager
!stopworker -name worker_2 -jobmanager my_jobmanager
!stopworker -name worker_3 -jobmanager my_jobmanager
!stopworker -name worker_4 -jobmanager my_jobmanager
% Stop the Job Manager
!stopjobmanager -name my_jobmanager
%%Stop the MDCE
!mdce stop
%%Uninstall the MDCE
!mdce uninstall
