It is also available a temporary storage local on compute nodes generated when the job starts and accessible via environment variable $TMPDIR. For more details please see the dedicated section of UG2.5: Data storage and FileSystems. On LEONARDO the $TMPDIR local area has 1 TB of available space.
$DRES environment variable points to the shared repository where Data RESources are maintained. This is a data archive area available only on-request, shared with all CINECA HPC systems and among different projects. $DRES is not mounted on the compute nodes of the production partitions and can be accessed only from login nodes and from the nodes of the serial partition. This means that you cannot access it within a standard batch job: all data needed during the batch execution has to be moved to $CINECA_SCRATCH before the run starts, either from the login nodes or via a job submitted to the serial partition.
Since all the filesystems are based on Lustre, the usual unix command "quota" is not working. Use the local command cindata to query for disk usage and quota ("cindata -h" for help) that will be available soon.
