What is the Storage Quota Limit in HPCC?

By default, each user is allocated a Home directory (/icto/user/$USER) and a Data directory (/data/home/$USER) for data storage. Additionally, three scratch directories (/scratch, /scratch2, /scratch3) are available for temporary storage during job execution. For FHS users, the Data directory is located at (/home/$USER). Faculty members and PIs have the option to purchase additional disk storage to expand their working space.

The Home directory (/icto/user/$USER) is designated for storing your program code, important files, and result data that require enhanced protection.

The Data directory (/data/home/$USER, /home/$USER) can be accessed through your home directory’s “data-home” folder (/icto/user/$USER/data-home). Please note that there is no data backup for this directory, so it’s advisable not to store any important data here without a backup copy.

The three scratch directories (/scratch, /scratch2, /scratch3) can be used as temporary storage directories for your programs. These directories are equipped with Solid State Drives (SSD), ensuring fast access times and superior data transfer rates for your running programs. However, please note that there is no backup for these scratch directories, and files that haven’t been accessed in the past 7 days will be automatically cleaned up by the system.
