We have the same issue as https://www.mathworks.com/matlabcentral/answers/2128851-why-is-the-mathworks-service-host-causing-issues-with-my-cluster-and-or-hpc and I see there that "For R2024a and newer, regardless of your licensing, the MathWorks Service Host is required"

When running in a cluster, this process is repeated every time MATLAB is started on a new node.

This not only causes uneccessary delays but it also piles up lots of data on the users' HOME space.

If we have 300 nodes, at ~640MB per node under $HOME/.MathWorks/ServiceHost a user would require more than 180GB just to host this data. This makes version 2024 not suitable for cluster environments.

How do we fix this issue?

Hi @Raffaele Potami MSH 2024.6 merges the data to a single node, removing the redundancy. MSH automatically updates the next time it runs. The amount of data recorded has also decreased.

We have the same issue here at JSC. It is not only the size of the data (users have a quota of 20GB for $HOME), but also the inodes (users have a quota of 82k for $HOME) in ~/.MathWorks which give us trouble.

For each node MATLAB adds another 10.000 files to `$HOME/.MathWorks/ServiceHost/<hostname>`.

If MSH 2024.6 fixes this issue where can we get it from?
