Storage System Configuration

The storage system disk space (total disk capacity: 5.07 PB) is divided into the user home directory area /home and /work, which is used for temporary storage of program output and intermediate files.

A usage limit (quota) is set for each user in /home, with a default value of 500 GB. If this limit is exceeded, you will not be able to write files. In that case, please delete unnecessary files or apply for a quota extension.

/work can be used as a program execution area and temporary storage area for output files. Please create your own directory and set appropriate access permissions before using it.

For details, please refer to Storage configuration and usage.
