Accessing Files on Mercury

Home Directories

All users of the Mercury computing cluster are given file storage space in their home directory (100GB for faculty, 100GB for PhD students, 5GB for MBA students, and 14GB for staff). Your home directory is private and cannot be shared.

  • /home/<BoothID>: user’s private home directory

Project Shares

Dedicated shared research space can be requested by faculty members. These directories are much larger than home directories (Terabytes) and are meant for storing large files associated with research projects. Faculty members can add/remove collaborators to these project shares as necessary. Project shares are the primary way that RP’s in particular can access meaningful disk space.

  • /project/<project-name>: network group share directory

Command line utilities

A common way of transferring files to and from a remote cluster is to use the scp command.

# copy a file to a local dir; use the same name for the file
$ scp <BoothID>@mercury.chicagobooth.edu:<src_dir>/myfile.txt <dst_dir>/.

# copy a file to a local dir; use a different name for the file
$ scp <BoothID>@mercury.chicagobooth.edu:<src_dir>/myfile.txt <dst_dir>/renamed.txt

# copy a directory using the recursive flag (-r)
$ scp -r <BoothID>@mercury.chicagobooth.edu:<src_dir> <dst_dir>

If you need to check the space available in your home directory or project share, you can use the df -h command.

# Check home directory space
$ df -h /home/<BoothID>/
Filesystem                                                     Size  Used Avail Use% Mounted on
sisyphus-n.chicagobooth.edu:/ifs/home/<affiliation>/<BoothID>  14G   7G   7G    50% /home/<BoothID>

# Check project share space
$ df -h /project/<name_of_project>

sftp

Another common way of transferring files is via sftp. One software package that provides cross-platform support for sftp transfers is Filezilla. Filezilla is an easy to use sftp client with a graphical user interface. The split window shows your local machine’s directory tree on one side, and the remote files in the other. Filezilla’s GUI allows simple drag-and-drop for transferring files.

Password

<BoothPassword>

Snapshots

Snapshots on Mercury are performed nightly for user home directories as well as project shares. Nightly snapshots are available for 30 days and provides users with a short-term file versioning system. Files older than 30 days are not recoverable. Note that “.snapshot” is a hidden folder not visible by directory listing commands. Here are some example commands for using snapshots.

# Navigate to the hidden ".snapshot" folder
$ cd ~/.snapshot

# View available snapshots taken in last 30 days
$ ls
gridhome_30day_2021-12-20_01-00
gridhome_30day_2021-12-21_01-00
gridhome_30day_2022-12-22_01-00
gridhome_30day_2022-12-23_01-00

# Restore a single file
cp ~/.snapshot/gridhome_30day_2021-12-20_01-00/file ~/target/folder/.

Mounting home directory on a Desktop

Users who are connected to the Chicago Booth network (either through a wired ethernet connection or through the Booth VPN) can access files on Mercury by mapping to their home directory. To map your home directory:
