EE Instructional Computing Resources

There are multiple remote server nodes to login to, using the names caddy01.stanford.edu to caddy18.stanford.edu. A status page for these nodes is available. Please select an underutilized node to run any large exercise or project, consulting that status page. You can connect to the lowest utilized system by going to caddy.best.stanford.edu. However, please note the number of the node for reconnecting a long running session.

Provision your home directory on FarmShare before connecting with OnDemand and/or X2Go interfaces

 

• As with FarmShare, a full service sunetID is required to access either remote Linux servers or any physical computer workstations in EE. Please see https://uit.stanford.edu/service/accounts/sunetids#eligibility for further sunetID information.
• Activate your home directory by making a ssh connection to the farmshare servers using instructions for your platform found at SSH for FarmShare.  NOTE: this only needs to be done one time.
• Frequently Asked Questions for OnDemand.

Two ways to connect to the caddy cluster:

OnDemand interface

• Please view a 5 minute video tutorial showing how to access and setup OnDemand here.
• Access the cluster via a web browser at this web page https://ondemand.farmshare.stanford.edu.
• Note: You’ll need to run a job under “Job Composer” to activate your OnDemand account.  You’ll need to build your desktop environment which will remain active for 90 days or until the end of the quarter when it will be reset.
• If your desktop displays the error "no vnc", close the browser window. Delete the interactive desktop. Go to the cluster pull down menu and select "caddy shack shell access". Use your SUNETID password and delete your "ondemand" directory with the "rm -rf ./ondemand" command. You'll need to be in your home directory which can be accessed by using the "cd" command before running the "rm -rf ./ondemand" command.

X2Go interface

• These systems are available to connect to from on-campus or via Stanford's VPN service. You can connect via SSH utilties/terminal or for a graphical environment, use X2Go. Good instructions for using SSH for FarmShare apply here as well, as long as you use caddy01 to caddy18 as host names.
• For X2Go, please see this instructional site on downloading the clients. XQuartz (https://www.xquartz.org/) is needed and must be install for the Mac client. We recommend selecting "Mate" as the desktop environment to use, and only "Mate" and "XFCE" are supported on our servers when selecting among the options in X2Go. A good example (step by step) of setting up X2Go is found here. The server name would be one of caddy01.stanford.edu, caddy02.stanford.edu, up to caddy18.stanford.edu while the VPN is active.
• If you have a newer farmshare account you may in fact have a .tcshrc.alias file that will be automatically loaded by your .tcshrc file present in your home directory. This file will conflict with the module commands above. Either rename the file or comment out its loading in the .tcshrc to resolve the issue.
