How can I prevent MATLAB 2024a from creating large hidden sge(number) folders with unnecessary logs and outputs when running jobs via SSH?

I work with SSH in MATLAB for two versions: 2020a and 2024a. When running the same code on both versions, I noticed that MATLAB 2024a creates hidden folders named sge(number). Inside these folders, there are additional subfolders for logs and outputs that I don't need. These folders can quickly grow to over 50GB, which is problematic. I believe this behavior is due to the version difference, but I'm unsure how to prevent it. Can you help me resolve this issue

Where exactly are those folders created?

[roi]

They created in folders named ServiceHost that in hidden foldes named .mathWorks

Hi roi,

The logs and output that are generated in large hidden sge(number) folders when running the jobs via SSH. There are some ways to handle them :

• Adjust Logging Level: It generates verbose logs. You need to adjust the logging level to reduce the amount of log data.

cluster = parcluster();
cluster.LoggingLevel = 'off'; % Options: 'off', 'minimal', 'normal', 'detailed'

• Cleanup Jobs: After the jobs are executed successfully, ensure that you are cleaning up the job's data.

delete(cluster.Jobs);

• Check Job Storage Location: MATLAB stores job data in the default job storage location. You can change this location to a directory with more space or a temporary directory that gets cleaned up regularly.

cluster = parcluster();
cluster.JobStorageLocation = '/path/to/your/desired/directory';

What you are seeing is the result of the MathWorksServiceHost (MSH). I would recommend that you reach out to our Installation and Licensing team. They will be able to provide next steps on how to go about this issue.
