  • Starting Fall 2018, all users should be using a machine named: which will randomly pick ilab1.cs, ilab2.cs or ilab3.cs. See iLab Machine Status to find status of all iLab servers and iLab desktop machines.
  • If you are using python, please follow Using Python on CS Linux machines instruction or many modules wont load properly.
  • If you are doing big data with Hadoop, Please see CS Hadoop Cluster information page.
  • Announcing a new 100GB disk space available for every user and can be accessed at /common/users/your_netid. See  Storage and Technology Options for more info. (July 30, 2018)
  • Please logout after using. If you don't logout, your X2Go or Remote Desktop session will be terminated and all unsaved work will be lost. If you would like to resume with the same session at a later time, open a terminal and  type
        in bash : echo 5 > /var/run/user/$UID/KeepSession 
        in csh: echo 5 > /var/run/user/$uid/KeepSession 

    Number 5 means you get 5 hours to get back to it. The maximum time you can set is 36 hours.  You need to redo the above command to extend the time. (July 26,2018)
