/home/$USER (environment variable $HOME);Each supercomputer user has a private home directory HOME=/home/$USER for a long-term storage of small amount of data. Only files needed for current computations should be stored there. Storing large files is not recommended.
Short-term backup copies of user data are created in the $HOME directories using the snapshot mechanism. Users have access to snapshots in their home directory under the .snapshot subdirectory.
The $HOME directory is not intended for temporary files used during computations!
For such temporary files a dedicated directoryTMPDIR = /lustre/tmp/slurm/$SLURM_JOB_IDis created for the duration of the computational job (see Section Temporary disk space for computations).
You can check the used space, remaining free space, and file limits using the quota command.
abcd@ui: ~ $ quota -s -f ~

The
quotacommand uses binary prefix bases, i.e., k=210, M=220, G=230, and T=240, not the decimal ones, i.e., k=103, M=106, G=109 oraz T=1012.
