HOME

Every user gets a HOME directory. Its path is always stored in the environmental variable HOME and most shells will expand ~ into it. The directory will be HOME_BASE/ACADEMIC_CLOUD_USERNAME/USER for members of projects in the HPC Project Portal and HOME_BASE/USER otherwise (e.g. legacy NHR/HLRN accounts), where HOME_BASE is one of the base directories for home directories (there is more than one and they may change in the future). The HOME directory is for a user’s

• configuration files
• source code
• self-built software

The HOME storage systems have the following characteristics:

• Optimized for a high number of files rather than capacity
• Optimized for robustness rather than performance
• Has limited disk space per user
• Backed up (some also have snapshots found at HOME_BASE/.snapshots)
• Has a quota

The HOME filesystems have slow-medium to medium performance. The HOME directories for each kind of user are given in the table below.
