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

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

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.

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 is available here.

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
