HPC Vega uses and integrates technologies for data storage with different characteristics, which provides a variety of different file systems. These provide SLING and EuroHPC users with storage capacity and predefined directories at their disposal.
|exa5||High Performance Storage||Lustre|
|ceph||Large Capacity Storage||Ceph|
Available file system
The following file systems are available for users:
|tmp||/tmp||Local temporary directory for all users|
|home||/ceph/hpc/home/||Home directory for users|
Home Directory is the user's home directory after logging in. Home directories are for storing, input, output, codes, scripts, etc. and should never be used for runtime temporary/scratch files, as this causes undue traffic that slows the operation of this file system. All home directories are made available to each compute node. Quotas are set in /home. Detailed information for quotas is available at this link.
Scratch Directory is the user's working directory. Each compute node has the file system mounted as /exa5/scratch/user. The scratch file system should be used when running your jobs. Files in this file system are subject to being removed after each run, so please copy any data you wish to save back to your home directory. Quotas are set in scratch directory. Detailed information for quotas is available at this link.
If you need permanent storage of large amounts of data, please contact the support team: firstname.lastname@example.org
|home||100GB||Size of home directory for each user|
|scratch||20GB||Size of scratched directory for each user|
Users should regularly check their disk space quota by using the following commands:
df -h /ceph/hpc/home/$USER df -h /exa5/scratch/user/$USER
