File Systems, Quotas and File Transfers

Global file space on Curie is shared with Ada cluster and is available on all compute, and login nodes. It is organized in the three file systems showing in the table below. Access to the allocated file space is through the indicated directories that are setup automatically for every user.

File System Directory Environment Variable Storage Hardware File Space Quota File Counts Quota Comments
Home /home/$USER $HOME GSS26 10 GB 10000 Upon login, you will be situated in /home/$USER. The use of this area is for small-to-modest amount of processing. Its space and file count limits are not extensible.
Scratch /scratch/user/$USER $SCRATCH GSS26 1 TB 50000 This is a high performance storage, intended to temporarily hold rather large files, and only for on-going processing that uses them. It is NOT backed up nor is it intended as long-term storage area. Please delete or move out of these area any files that are not frequently used.
Tiered /tiered/user/$USER $ARCHIVE GSS26 10 TB 50000 This is an archival file system intended to hold valuable data files that are not frequently used. Please delete or move elsewhere files that have been inactive for extended periods. Quotas will be in place, but space allocation is extensible upon justification and availability. /tiered is not accessible from the compute nodes.

Quotas & File Use: the showquota command

A user can run the showquota home-wrapper command to display file use on Ada. Future versions of the command will include use of the tiered file system. Below is a sample output of command showquota.

$ showquota
        Disk Usage and Limits    |     File Usage and Limits
Disk       Disk Usage      Limit    File Usage      Limit
/home        195.6M         10G        1464         10000
/scratch     1.394G         1T         2898         50000

Transferring Files

Data transfer utilites scp, sftp, and rsync are available Curie login nodes. All Curie login nodes have 1 Gigbit Ethernet connection to the intra-campus network. These are suitable for small-to-medium sized data transfers. For massive data transfer, use GridFTP or bbcp on the Ada's fast data transfer nodes: ada-ftn1.tamu.edu and ada-ftn2.tamu.edu to utilize 40 Gigabit Ethernet connection to Ineternet2.

For transferring files on Curie (or Ada) to/from a Windows machine, please use WinSCP.
