How To Connect To The Compute Cluster

Some things to know first:

Connect with SSH (command-line only)

    From Windows

    • Download and install PuTTY. NOTE: PuTTY is installed on the Windows computers in the ENS labs.
    • Open PuTTY from the Start Menu.
    • In the box labled "Host Name (or IP address)", type ens-hpc.engr.colostate.edu and click "Open" to connect.
    • Log in with your local compute cluster account.

    From Linux or Mac OSX

    • Open a terminal window and type:
      ssh <your_username>@ens-hpc.engr.colostate.edu
    • Log in with your local compute cluster account password.

Connect with SSH (Graphical Forwarding)

    Windows (method 1)

    • Download and install Xming
    • Download and install PuTTY
    • Start Xming (this will put a "X" icon in the taskbar).
    • Start PuTTY.
    • Under "Connection," expand SSH and click on X11. Check "Enable X11 forwarding."
    • In the box labled "Host Name (or IP address)", type ens-hpc.engr.colostate.edu
    • Go to the section Session at the top left and under saved sessions, click on "Default Settings" and click save. This will save the setting for next time.
    • Click "Open" to connect
    • Log in with your Engineering user name and password.
    • Once you are connected, check that applications will open on your computer by typing xclock. This should display a small analog clock.

    Linux

    • Open up a terminal window and type:
      ssh -XC machine_name.engr.colostate.edu
    • Log in with your Engineering user name and password.

    Mac OS X

    In order to run programs with X-forwarding on Macintosh OS X, you need SSH (which is installed by default) and X11 for Mac OS X, which is freely available.

    • Download and install Xquartz or X11.
    • Open a terminal window
    • At the prompt in the terminal window, connect to a compute server by typing:
      ssh -X username@machine_name.engr.colostate.edu
      or, if the -X gives you problems
      ssh -Y username@machine_name.engr.colostate.edu
      Note: The -X enables X-forwarding. Sometimes, you might need to use -Y instead, which enables trusted X-forwarding.
    • Run the application you wish to use from the command prompt.
