Access Matlab on the DECS Compute Servers via SSH from OSX

The following are instructions for running Matlab on one of the DECS compute servers using OSX.  This enables Matlab to be available wherever you have Internet access.  Older versions of Mac OSX will have an X11 client installed.  Newer versions will need to download and install XQuartz to use Matlab with a GUI interface.

You may also want to consider using  Remote Desktop Services.

  1. Open a terminal window.  The terminal app is located in the utilities folder (Macintosh HD > Applications > Utilities).  You can also drag the application to the dock.
  2. In the command window enter ssh -Y (replace "username" with your engineering username).
  3. Press the Enter key on your keyboard and you will be prompted to enter your engineering password.  As you enter your password, it may appear as if no text is being entered, this is intentional, type your EGR password and hit Enter.
  4. After logging into scully, enter computeuse and hit Enter.  This will give you a list of DECS available compute servers, such as brock, byron, deus, helper, etc.
  5. Pick a compute server (typically you want the server with the lowest LOAD)
    Type in the following command:
    ssh username@computeserver -Y (replace username with your engineering username and computeserver with the hostname of a compute server)
    For example: ssh Sparty@helper -Y or Sparty@byron -Y

  6. If you've never logged into a particular compute server you may see the following message type yes and press Enter.

  7. Type matlab into the terminal and press Enter to launch Matlab.
