Table of Contents
Storage on Aurora
Storage in the Aurora cluster is organized as detailed by Lunarc. Read the following: http://lunarc-documentation.readthedocs.io/en/latest/quick_reference/#file-systems
The home folders are maintained and backed up by Lunarc, and they are in a special storage machine dedicated to users.
Nuclear, Particle and Theorerical Physics
Dedicated Shared storage server on Aurora
In particular, the HEP nodes dedicated storage usable by members of all divisions is accessible on hep nodes au[193-216] at this path:
/projects/hep/nobackup/
The organization of data in the above folder is as follows, and users are encouraged to enforce it:
| Folder name | Folder purpose | Description | Subfolders |
|---|---|---|---|
| software | Application software | This folder hosts software that is not accessible via cvmfs (see later). This usually includes user/project specific libraries and frameworks. | /np for Nuclear Physics users |
/pp for Particle Physics users |
|||
/tp for Theoretical Physics users |
|||
| shared | Data that will stay for long term | This folder should be used for long-term stored data. For example, long-term data sets or data needed for the whole duration of a phd project or shared among people belonging to the same research group. | /np for Nuclear Physics users |
/pp for Particle Physics users |
|||
/tp for Theoretical Physics users |
|||
| scratch | Data that will stay for short term | This folder should be used for short-term stored data. For example, data needed for a week long calculation or temporary calculation. This folder should be considered unreliable as its contents will be purged from time to time. The cleanup interval is yet to be decided | /np for Nuclear Physics users |
/pp for Particle Physics users |
|||
/tp for Theoretical Physics users |
|||
| users | Copy of Iridium User homes | This folder contains a copy of each user's private home folder on Iridium. DO NOT use this on Aurora. This folder will be used as a backup until we plan some other Iridium backup. | /<username> each user her own folder |
/npguests/<username> for Nuclear Physics guests |
|||
/ppguests/<username> for Particle Physics guests |
Other special folders:
/cvmfs | Special folder containing CERN maintained software | user cannot write | This special folder is dedicated to software provided by CERN. This folder is read-only. Usually the content of this folder are managed via specific scripts that a user can run. If you need to add some software that you cannot find, contact the administrators. | /geant4.cern.ch for Nuclear Physics users |
|---|---|---|---|---|
/atlas.cern.ch for Particle Physics users |
Dedicated storage for Particle Physics
Description yet to come.
Storage on Iridium
The Iridium storage is still accessible at
/projects/hep/iridium/
Please refer to the documentation at basic_information for it.
Additional dedicated storage
There are two storage servers installed for the exclusive use of particle physics. The recommendation is to use these instead of /project/hep/nobackup so to give space to the other users of it.
'/project/hep/fs2' is a symbolic link to '/project/hep/nobackup'
| Storage path | Folders | Intended usage | Size |
|---|---|---|---|
| '/project/hep/fs3' | 'share' | data that is meant to stay | 35TB |
| '/project/hep/fs4' | 'scratch' | temporary data | 35TB |
Mathematical Physics
At the moment, only the user folders are available. We are negotiating a 10TB common storage with Lunarc. More information is soon to come.
