Student Systems

There are 2 different group of Student systems, they are part of iLab cluster and is described as follow:

1.General Student Systems 
Student systems a.k.a. iLab cluster are the main general computing resource for courses, student projects and faculty sponsored users. These systems are available to students, faculty, and staff.
  • If you are accessing the systems from home, please connect to ilab.cs.rutgers.edu. That will give you one of four large servers, iLab1, iLab2, iLab3 and iLab4. You can also access any iLab Desktops distributed in offices at Hill and CoRE especially when you need to run virtual machines.
  • As of Fall 2022 , we added 4  other GPUs servers (rLab1, rLab2, rLab3, rLab4) and iLabU.cs (running newest version of Ubuntu LTS for compatibility testing) to the iLab cluster.
  • The large servers known as iLab.cs have 32 Nvidia A4000 GPUs total, rLab1-rlab4 have a total of 32 GPUs (24 Nvidia 1080ti and 8 TitanX GPUs).  As of Fall 2022, these GPUs are accessible via  Job Scheduler only.
  • We also run Jupyterhub, a web programming interface for Python and Scala.
  • If you want to use a system in person, we have desktop systems, Instructional Labs Systems, in Hill 120, Hill 248 and Hill 252
  • For more details, see  specifications and status of these machines.
2. Graduate Systems

Graduate student offices are part of iLab cluster and primarily used as a desktop system for the office.

For significant work, grad students should probably use our machines named ilab.cs.rutgers.edu and rlab{1-4}.cs.rutgers.edu described above.

Ph.D. students may run/request VMs for special project, if necessary, this vm could last as long as they are enrolled in the program. We normally use Ubuntu. The VM is limited in CPU and Memory and not meant for computing. Send requests to help@cs.rutgers.edu.

Note that iLab desktops are workstations with monitor, but they are sometimes used by people connecting to them remotely. Please don’t turn them off or reboot them, since that will interfere with other people using them remotely.

IMPORTANT: You must have an account on CS Linux systems before you can use iLab machine. See Getting Started page for more details about using our resources.

Unless noted, our servers and desktop systems have the same basic software, the current Ubuntu Long Term Support (LTS)  Linux Operating Systems.

All our machines are accessible remotely via a web browser like Google Chrome, Firefox or Safari using WebLogin, SSH client like ssh command on MacOS and Linux or Bitvise Client on Windows. (See Video tutorial or SSH HowTo), X2GO and Windows Remote Desktop or come to one of the rooms in Hill48, Hill 252 or Hill 254.

For more details, see  specifications and status of these machines. Please be aware that these machines have preset limitations to prevent abuse and runaway processes. 

For specific instructions a variety of topics, including accounts on the system and how to use various programming languages there, see the

Account Cleanup

Your CS Linux account are normally deactivated when you are no longer have role with Computer Science or no longer taking any CS classes. Normally account deactivation is done about 4 months or a semester after. For graduated CS Major, we normally send a warning to your official university address NetID@rutgers.edu  to warn you about account deactivation.
