The home file system

The home file system

The home file system contains the files you normally use to run your jobs such as programmes, scripts, job files. There is only limited space available for each user which is why you should never store the data that you want to process or that your jobs will produce in your home.

By default, you have 15 GB disk space available. Your current usage is shown when you type in the command:

quota -s

The home file system is a network file system (NFS) that is available on all login and compute nodes. Thus, your jobs can access the home file system from all nodes. The downside is that the home file system is not particularly fast, especially with the handling of metadata: creating and destroying of files; opening and closing of files; many small updates to files and so on.

For newly created accounts, the home directory only contains a link to your directory on scratch-shared.
