User Home

Each user has a home directory ($HOME) that can contain up to 10 GB of data. It is intended to store user configuration files and personal data. You are NOT supposed to run jobs from your home directory.

The user home directory is purged once the user account expire.

Project Persistent Storage

The Project Persistent storage is intended to share data amongst the members of a project. You can see this workspace as the project home directory. Typically, this space can be used to share applications and libraries compiled for the project. Just like the user home directory you are NOT supposed to run jobs from your the project persistent space.

The project persistent storage is located at /projappl/project_<project-number>.

The project persistent directory is purged once the project expire.
