Facility and Resources: Grad Labs

This page provides information about the graduate computing labs in Math 224 and Math 225/227.

Policy for use

The policy is set by the computer committee.

  • Food and drink: Obviously food/drink can be harmful to computers; yet, the labs also serve as a place for students to work together on lengthy research or homework projects. It is therefore unreasonable to expect grad students to stick to a hardline “absolutely no food/drink allowed” policy. Instead, the department has provided large center tables—away from equipment—so that you can work in a manner convenient to you, yet keep food/drink away from the equipment. Note that campus janitorial staff does not enter the labs, and our computer support staff enters the labs only occasionally. You must clean up after yourself, and you must put all perishable food items/remains in the hallway. (The receptables inside the lab are emptied only occasionally.) Concerning this policy, one rotten apple can truly ruin the whole barrel: it could take as little as one person who abuses the open nature of this policy, unintentionally has a food-related accident that leads to damage of expensive equipment, and we will switch to a hardline policy.
  • Whiteboard usage: Use it freely but 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 (using a different computer, or ask someone to contact the staff on your behalf).
  • Locking your terminal screen: You may lock the screen to briefly leave the lab, for example in order to go to the restroom or to get a book from your office. But if you will be gone for more than 5 minutes, you must log out. (Even if the lab is rather empty, it can fill up unexpectedly in your absence.) If someone discovers a locked terminal and the owner has not appeared for 5 minutes, please contact the computer system staff and specify which machine should be unlocked by the system administrator.
  • Noise level: Students may work together on projects, which obviously requires talking, but please keep in mind that other people in the lab may prefer a quiet environment. You may listen to music at reasonable volumes using your own headphones.
  • Graduate Computer Lab Library and policy.
  • 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

These systems have all software that comes standard with Ubuntu, and in addition have various locally-installed software. 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 background jobs or for heavy-duty foreground jobs.

Nonetheless, grad students sometimes need to run stuff in the background on machines that people sit in front of. Before you ever attempt to put stuff on another machine or in the background of a lab machine, learn how to do this properly.

Other systems available to grad students

Heavy-duty computing

The following systems have Intel Pentium 4 with Hyper-threading, 3.0 GHz, 4096 MiB RAM. Before using these machines, be sure to learn how to run jobs remotely and in the background.

  • chivo1.math.arizona.edu
  • chivo2.math.arizona.edu
  • chivo3.math.arizona.edu
  • chivo4.math.arizona.edu

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.

  • gila.math.arizona.edu (for SSH: Intel Pentium 4, 2.8 GHz, 512 MiB RAM)
  • iguana.math.arizona.edu (for VNC: Intel Pentium 4, 2.8 GHz, 2048 MiB RAM)
