The Grad Lab

The Graduate Physics Computer Lab is located in RLM 9.326. It is available 24 hours a day, 7 days a week (as long as the University and RLM are open, anyway).

You can log into any of the Grad Lab Linux machines (all of the machines in the Lab except for the Windows workstation) using your physics account login. (The Windows machine is managed by the PMCL. Contact them for information on getting an account on that machine.)
Public Machines

There are several Linux machines in the Grad Lab. For these machines, you can log in directly at the console. All of these systems are running the X Windows graphical interface. (You can choose from several window managers, including KDE, Gnome, and others. You can also log in using the standard text console.) You can also log into any of these machines, as well as the other public machines, via SSH. We support both SSH1 and SSH2; if you have a choice (and you usually do), we recommend using SSH2. If you absolutely have to use TELNET, you can do so only from within RLM. However, you should always use SSH unless there is an extremely good reason not to (and there usually isn't).

The 15 general-purpose Linux machines are named linux1.ph.utexas.edu through linux15.ph.utexas.edu. All of these except for linux2 and linux15 are located in RLM 9.326 (the Grad Lab). There is also a remote computational Linux machine named twist.ph.utexas.edu.
Performance Information

The Linux machine specifications are as follows:
  • linux1, linux3-linux15: 3.0 GHz Pentium 4 with 1 GB of RAM
  • linux2: Dual 450 MHz Pentium III with 1 GB RAM
  • twist: Dual 3.2 GHz XEON with hyperthreading and 3 GB RAM
Removable Media and CD Burning

All machines in the Grad Lab in RLM 9.326 have a floppy drive and a DVD Reader with CD-R/RW burner. CD-ROMs should work automatically work (just insert the disk and Linux should auto-detect and mount it). The easist way to use floppy disks is via the mtools package. For more information on using removable media, see the Linux FAQ. For information on using the CD recorder to burn a CD-R or CD-RW, see the CD burner instructions.
