CASLab Overview

CASLab is series of labs and computers hosted and maintained by the School of Computing, with a satellite lab in Jeffrey Hall managed by Queen’s ITS. The lab is made up of machines that dual-boot Windows and Linux. All systems make use of a shared network drive hosted by a main Linux server running Samba and NFS. This means you can save your work on Windows and continue working on it in Linux, or even at home.

File Storage

CASLab has a central storage server (Zeus) that you can save files to. This storage is available on Windows as the Z: drive. On Linux, it is your home directory (~) mounted as /cas/student/<your-netid>/. If you need to share files between Windows and Linux, save them in the directory called Zdrive (/cas/student/<your-netid>/Zdrive/), which is what gets mounted in Windows.

This storage space can be accessed from your own computer – on or off campus – by using SFTP. Instructions for how to use SFPT can be found in the How To section.

Labs

At this time, the main CASLab facilities are located in Goodwin Hall 230, 248 and Walter Light 310. In addition, students can log into CASLab in Jeffrey Hall room 155 and in most computers in Beamish-Munroe Hall.

Walter Light 310

This lab contains around 20 PCs. Each PC is equipped with a big beautiful 32″ 4K monitor and Thunderbolt, which can be connected to an external GPU (eGPU) if you require more graphics power. You may also want hook your laptop to one of the monitors using the extra HDMI cable attached to each.

WLH 310 also has ample table space for you to work on your own laptop independently or with a group. There’s a podium and a projector screen for presentations and a whiteboard for brainstorming.

Goodwin 248

This lab contains 5 group tables with 55″ TVs attached to them that you can hook your laptop up to. Each table has 4 A/C power outlets and 4 USB power outlets. These tables are perfect for working in groups on assignments or projects. There are also a few PCs (like the ones in WLH 31o) on height adjustable desks if you need to work independently.

Goodwin 230

This lab contains 6 tables for group/independent work with power outlets and a whiteboard. There is also a large TV at the front of the room that you can use.

Jeffrey 155

The lab is located in the basement of Jeffrey that is run by ITS. It can be accessed by anybody at Queen’s without an iButton. There are 2 rooms with over 50 PCs. Students log in with their Queen’s NetID and password on the AD domain (ie. not with their CASLab accounts). You can, however, still access your CASLab files from these machines by clicking the icon on the desktop.

CASLab Linux Servers

CASLab also has a number of Linux machines you can remotely log into. They are:

  • linux1.caslab.queensu.ca
  • linux2.caslab.queensu.ca
  • linux3.caslab.queensu.ca
  • linux4.caslab.queensu.ca
  • linux5.caslab.queensu.ca
  • linux6.caslab.queensu.ca

You can log into each of these machines using SSH on the command line, or get a graphical interface by using x2go. Instructions for how to connect are in the How To section.

If you are connecting via the command line, consider using the Linux Gateway at linux.caslab.queensu.ca (no number). Logging in to this machine will show you all the machines available, how many people are currently using them, and what load they are currently under.
