    1717 * $PROJECT: In JUMO, data and computational resources are assigned to projects: users can request access to a project and use the resources associated to it. As a consequence, each user can create folders within each of the projects he/she is part of (with either personal or permissions to share with other project members). For the DEEP project, the project folder is located under `/p/project/cdeep/`. Here is where the user should place data, and where the old files generated in the home folder before the JUMO transition can be found.

    19 The DEEP-EST system doesn't mount the $SCRATCH and $ARCHIVE file systems from GPFS, as it is expected to provide similar functionalities with its own parallel file systems.

    2121The following table summarizes the characteristics of the file systems available in the DEEP-EST and DEEP-ER (SDV) systems. '''Please beware that the `$project` (all lowercase) variable used in the table only represents any !JuDoor project the user might have access to, and that it is not really exported on the system environment.''' For a list of all projects a user belongs to, please refer to the user's [https://judoor.fz-juelich.de/login JuDoor page]. Alternatively, users can check the projects they are part of with the `jutil` application:
