The BWI Lab Machines are managed in-lab, and are not part of the cs main network. As such, your CS lab machine credentials will not work on the BWI lab machines. Please see Requesting Credentials. Once you have credentials, they will work on all BWI Lab Machines.

If you are looking for how to access the LARG compute cluster learning nodes, those machines are managed by CS Help and accessible to LARG lab students. Contact [email protected] to gain access to LARG learning nodes on the CS managed compute cluster.

Who manages lab machines:

  • Corrie Van Sice
  • Keith Fritz
  • Justin Hart

~~ IMPORTANT NOTES ~~

  1. The Lab Machines are NOT to be rebooted or shutdown. They are all encrypted and a password is required to boot the machines. This password must be entered in-person. So, if a machine is shut down, expect delays, since access will be cut off until a lab member is on-site.

  2. Do not make global changes to packages. This means changes to common (i.e. all users depend or use them) packages such as opencv cuda drivers of any kind python, etc. If you need to make these changes for your own use, the correct way to do it is to make the change for your-user only. This can be done by installing new packages to ~/.local and adding them to your $PATH manually.

Lab Machine Description

We have several 'classes' of Lab Machine. There are all accessible as public hostnames at HOSTNAME.csres.utexas.edu

Deep Learning Nodes

dr-perceptron, dr-light, commander-sigma

Remote Access

Access the lab machines remotely via a secure shell. You will need a LARG/BWI username and password - if you do not already have one, please request one from your lab admin.

SSH

You can ssh into any of the lab machines by using it's public address, e.g.

ssh [email protected]

SSH access is restricted to those on the UT network or those that have their private keys installed on the host. In either case, you will need to get onto the UT VPN (either for access, or to initially install your keys). You can read more about this here.

TeamViewer

You can also access these machines via TeamViewer. The password is at http://stache.utexas.edu under the entry "BWI Teamviewer." If you do not have this entry in your account, please email/slack a lab admin. The IDs for each machine are listed below:

Machine Name ID
drperceptron 1 043 218 977
commander-sigma
dr-light 1 056 996 134

Requesting Credentials

Please reach out to your immediate mentor/instructor/advisor to get credentials on the BWI lab machines.
