General ARCC Troubleshooting

For general issues please see our Known Issues page to see if the problem could be caused by something that we already are aware of and recommended solutions or work arounds.

General FAQs:

 My home directory is full, can I get more space?

My home directory is full (I’m getting a quota limit warning). Can I get more space?

  • Rarely do we increase /home directory space and ask that you please clean up any unnecessary files first.

  • To determine what is taking up space in your home directory, you can cd to our home directory, then run a du -h --max-depth=1 command to determine what’s taking up space in your home folder.

  • You may want to move files from your /home directory to your /project directory, or if your data isn’t needed long term or is backed up elsewhere, you may move it to your /gscratch directory.

  • If the problem persists, email arcc-help@uwyo.edu to describe your issue.

 Can I have sudo access?

May I have sudo access on Beartooth?

Users are not permitted to have sudo access. Email arcc-help@uwyo.edu to request anything you need installed or changed on the cluster.

 I can’t access my Alcova storage

I can’t access my Alcova storage

This can happen for a number of reasons.

If you’re trying to access Alcova from off campus, you will need to use the UWyo VPN to get onto the UWyo network.

If this doesn’t help, please contact ARCC at arcc-help@uwyo.edu so we may troubleshoot your issue.

 My UWYO account is locked/disabled

My UWyo user account is locked/disabled, can ARCC restore it so I can use ARCC resources?

  • No, ARCC does not manage UWyo accounts, but to start troubleshooting, go here: Password Resets and Account Lock Outs

    • If you are an external collaborator, you will need to contact the UWIT Accounts Office to reset your password

    • Otherwise, call UW IT Helpdesk to have it unlocked at 766-HELP ( on campus: 6-4357)

    • For further information on UWyo accounts see UW Accounts FAQ

 Do I need a smart phone to use two-factor for ARCC Services?

Do I need a smart phone to use two-factor for ARCC services?

  • No, there are other options:

    • You have to purchase a Yubikey and then self enroll the key or have it set up by UWIT.

    • You can enroll in any phone number or device on Duo.

      • When logging into Beartooth using the landline method, type “<your password>, phone“ and your enrolled number will get a call.

Beartooth

How do I access Beartooth when I am not on the UWyo network?

  • Beartooth's login nodes are on the Science DMZ network outside of UWyo firewalls. Meaning you can log into Beartooth from anywhere as long as you have an internet connection and a terminal or ssh client.

How do I run my code on Beartooth?

  • You must submit your code to the job scheduler. Running code on login nodes is not permitted.

    • For more information about the job scheduler please see our page on Slurm.

How do I find out which software packages are installed/available on Beartooth?

  • While logged into Beartooth, executing the command "module spider" will list all modules installed on Beartooth.

$ module spider
To learn more about a package execute:

$ module spider Foo

where "Foo" is the name of a module.

To find detailed information about a particular package you
must specify the version if there is more than one version:

$ module spider Foo/11.1
