Graduate Labs

This page provides information about the graduate computing labs in Math 401N and Math 225/227.

Policy for use

The policy is set by the computer committee.

  • Food and drink: Food/drink can be harmful to computers! We provide large center tables for food. Please keep food/drink away from computers. We have no janitorial service in labs. Clean up after yourself, and put all food remains in the hallway.
  • Whiteboard usage: Clean it after you are done. Please don't let the marker ink dry on the whiteboard.
  • Printing: Do not waste! Recycle unwanted printouts.
  • Rebooting computers: Do not do so! There may be important background jobs you are unaware of. If a computer hangs or otherwise acts strangely, please contact the computer support staff.
  • Locking your terminal screen: You may lock the screen to briefly leave the lab.If you will be gone for more than 5 minutes, you must log out.
  • Noise level: Please know that some students may prefer a quiet environment.
  • Keep the computer support staff informed: contact them on the status of the computers, printers, accessories, room tidiness, special needs, etc.

Lab systems running Ubuntu GNU/Linux

There are six Ubuntu computers in each room.

Any grad student in our department with a network account can log into these systems. Other than chivo1 through chivo4 (see below), these machines are not suited for cpu-intensive jobs.

Occasionally, grad students may run jobs on lab machines. Before you ever attempt to run jobs on another machine or in the background of a lab machine, learn how to do this properly.

Windows Computers

There is one Windows computer in each room.


There is a scanner attached to the Windows computer in M224.


There is a Brother HL5370 laser printer in M227, but it will be replaced by the Konica in 401 in the future.

Other systems available to grad students

High Performance Computing


Gateway systems

These systems are not for performing computations. Use them to access your files, create ssh tunnels, print things, maintain your website, and so on.

  • (for SSH: Intel Pentium 4, 2.8 GHz, 1 GiB RAM)
  • (for VNC: Intel Pentium D, 2.8 GHz, 4 GiB RAM)
