The /capstor/store mount point of the Lustre file system capstor  is meant to replace the GPFS /project and /store for project storage. The mount point is accessible from the User Access Nodes (UANs) of Alps vClusters (except for Eiger, for the time being).

The mount point features subfolders named after tenants and customers: on daint.alps, the only tenant currently available is CSCS, therefore all customer folders are located under the folder /capstor/store/cscs 

  • UserLab customers can access their project folder on daint.alps  with the $PROJECT environment variable, that targets the personal folder /capstor/store/cscs/userlab/group_id>/$USER.
    Please note that users need to create their own sub-folders under the project folder, as they are not created automatically.
  • Contractual partners will find their project folder under the corresponding contractual name listed in /capstor/store/cscs. For instance, EMPA users will have their projects listed under the empa folder, and so on 

Data on /capstor/store is backed up with no cleaning policy: it provides intermediate storage space for datasets, shared code or configuration scripts that need to be accessed from different vClusters. The performance of the Lustre file system (read and write) increases using larger files, therefore you should consider to archive small files with the tar utility.

Quota

Access to /capstor/store is granted to all users with a production or large development project upon request at the time of proposal submission: please note that applicants should justify the requested storage as well as they do for compute resources. Each group folder has a quota space allocated that allows maximum 1 M files and 150 TB of disk space at present.

Expiration 

All data will be deleted 3 months after the end of the project without further warning!
