    2 On the DEEP-EST system, three different groups of filesystems are available:
    34
    4  * the [http://www.fz-juelich.de/ias/jsc/EN/Expertise/Datamanagement/OnlineStorage/JUST/Filesystems/JUST_filesystems_node.html JSC GPFS filesystems], provided via [http://www.fz-juelich.de/ias/jsc/EN/Expertise/Datamanagement/OnlineStorage/JUST/JUST_node.html JUST] and mounted on all JSC systems;

     6On the DEEP-EST system, three different groups of file systems are available:
    57
    6  * the DEEP-EST (and SDV) parallel BeeGFS filesystems, available on all the nodes of the DEEP-EST system;
     8 * the [http://www.fz-juelich.de/ias/jsc/EN/Expertise/Datamanagement/OnlineStorage/JUST/Filesystems/JUST_filesystems_node.html JSC GPFS file systems], provided via [http://www.fz-juelich.de/ias/jsc/EN/Expertise/Datamanagement/OnlineStorage/JUST/JUST_node.html JUST] and mounted on all JSC systems;
    79
    8  * the filesystems local to each node.
     10 * the DEEP-EST (and SDV) parallel BeeGFS file systems, available on all the nodes of the DEEP-EST system;

    10 The users home folders are placed on the shared GPFS filesystems.  With the advent of the new user model at JSC ([http://www.fz-juelich.de/ias/jsc/EN/Expertise/Supercomputers/NewUsageModel/NewUsageModel_node.html JUMO]), the shared filesystems are structured as follows:
     12 * the file systems local to each node.

     14The users home folders are placed on the shared GPFS file systems.  With the advent of the new user model at JSC ([http://www.fz-juelich.de/ias/jsc/EN/Expertise/Supercomputers/NewUsageModel/NewUsageModel_node.html JUMO]), the shared file systems are structured as follows:
    1115
    1216 * $HOME: each JSC user has a folder under `/p/home/jusers/`, in which different home folders are available, one per system he/she has access to.  These home folders have a low space quota and are reserved for configuration files, ssh keys, etc.
    … …  
    1418 * $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 has a folder within each of the projects he/she is part of. For the DEEP project, such 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.

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