-===== Connect to the HPC system: =====+====== Orientation ======
  
  
-There are two methods of connecting to the HPC system. Clients that are connected to the Grinnell College network can SSH to the cluster. Clients that are off-campus can connect to the cluster in a web browser by visiting https://hpc.grinnell.edu+If you've not had much exposure to running computational workloads on an HPC cluster, this video is a brief but very helpful introduction to an HPC cluster. It is recommended that you watch this video before proceeding with the tutorials linked below.
  
-1. SSH: Use a command line application (Terminal, Powershell, etc) to connect to the cluster. You'll be prompted for your Grinnell College account password. 
  
-    ssh [username]@hpc.grinnell.edu+{{ youtube>AiTUXhmDcZ0?large }}
  
 +====== Tutorials ======
  
-2. Web-based access: Direct your browser to https://hpc.grinnell.edu. You'll be ushered through Single Sign On (including Duo MFA) and will be logged into Open On Demand where various applications and functions are available.

-===== Moving files to/from the HPC system: ===== +[[tutorials/scheduler|Submitting Jobs]]
- +
-1. There are command line options for moving files between your client (laptop/office computer) and the cluster. One such option is ''scp'' or //secure copy//. For example, to copy a file named example.txt from your local computer to your home directory on the HPC system: +
- +
-    scp ~/example.txt [username]@hpc.grinnell.edu:~/ +
- +
-More information on ''scp'' [[https://man7.org/linux/man-pages/man1/scp.1.html|is available here]]. Because this option relies on SSH, this option only works from a computer connected to an on-campus network. +
- +
- +
-2. Another command line option is ''rsync''. ''rsync'' will synchronize files and directories between a source and destination (i.e. your local computer and the HPC system). +
- +
-    rsync /local/directory [username]@hpc.grinnell.edu:/remote/directory +
- +
-More information on ''rsync'' [[https://www.tecmint.com/rsync-local-remote-file-synchronization-commands/|can be found here]]. Because this option relies on SSH, this option only works from a computer connected to an on-campus network. +
- +
- +
-3. If you prefer a graphical user interface, you can use SFTP clients such as [[https://filezilla-project.org/download.php|FileZilla]] or [[https://cyberduck.io/download/|Cyberduck]] +
-The connection details for these applications will be: +
-  - Protocol: SFTP +
-  - Server: hpc.grinnell.edu +
-  - Port: 22 +
-  - User: [username] +
-Because this option relies on SSH, this option only works from a computer connected to an on-campus network. +
