The ilab includes

  • Three Linux Centos 7 servers, each with 1 TB of memory, 80 cores, and 8 Nvidia 1080Ti GPUs. 
  • 47 desktop systems, in several rooms on the secord floor of Hill Center
  • An instructional Hadoop cluster

See Student systems for more information on how to use these systems.

Announcements

  • Attention CS416 students. Please be aware that fuse mount point must be set in /tmp/ or /freespace/local/ or your program will hang. The reason: root has no access to home dir and fuse is run setuid root.
     
  • Please be aware that iLab machines have a new CPU Limit policy enforced limitation to prevent abuse and runaway processes. 
     
  • For students learning to program with fork,  see  Preventing Fork Bomb on Linux 
     
  • Dropbox  No longer works due to new requirement of glibc 2.19 or higher and ext4 file system as of Oct 15 2018. Use Scarletmail Google Drive. You have unlimited space there instead of 2GB from Dropbox.
     
  • For users who still have issues with logging in or access, please go to Core 211 between 10:30a-5pm to resolve your issues. If you own it, please bring your laptop (Sept 18, 2018)
     
  • If you have issue connecting to CS machines, make sure to check if your IP is blocked and how to get around the block.
     
  • Starting Fall 2018, all users should be using a machine named: ilab.cs.rutgers.edu 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)
     
  • For those users who use emacs on x2go, please use: emacs-23.1 to avoid compatibility issue.
     
  • All iLab machines have been updated to the most recent security update (Jan 15, 2018).
     
  • There are reports that some people have Keyring issue. Try to use your NetID password to unlock it. If you continue to have problem,  follow this QuickFix to Gnome Keyring Password instruction.
     
  • If you are new to CS Resources, see Beginners info

 

Finding a Computer to Use

  • We recommend remote users to use machine named: ilab.cs.rutgers.edu which will randomly pick ilab1.cs, ilab2.cs or ilab3.cs. If you prefer other machines, please  look at the usage graphs to find other iLab machines.
     
  • If you have issue with specific iLab machine, report it to help@cs.rutgers.edu, check  Status of iLab Machines and pick a different machine.
