1. You need to request an HPC account
   and

2. You must become a member of a project on the cluster.

   1. If you are a PI, you may request a project be created.

   2. If you are not a PI, a PI may request a project creation on your behalf, then request you be added as a member.

Step 2: Logging

...

in and Access the HPC

1. Now you’re ready to connect/login to the cluster! Note: you should not be connected to the UWguest wireless network.

2. Users can log in 2 ways:

   1. Login over Command Line Interface (most commonly method of logging into HPC). Learn how.

   2. Login through Southpass: ARCC’s OnDemand resource, which makes ARCC’s HPCs available through your web browser. Learn how.

3. Once in a command line interface, type in “ssh <username>@<clustername>.arcc.uwyo.edu” and press enter.

   1. For example: ssh arccuser@beartooth.arcc.uwyo.edu

      1. The first time you log in you will get a message saying the ‘authenticity of the host … can’t be established' and asking if you ‘are sure you want to continue?’.

      2. Enter ‘yes’.

   2. You will then see a Notice to Users and a Two-factor Authentication message, with your mobile device ready, enter your password and accept the Duo Mobile (2FA) challenge when it pops up.

4. Once you are connected, a bunch of text will scroll by. This will vary depending on the cluster. On Beartooth, for example, there are usage rules, tips, and a summary of your storage utilization across all projects that you are part of.

   1. Note that when you are logged in, the command prompt will look something like this: [arccuser@btlog1 ~]$

      1. This shows your username and which login node you are currently utilizing. The login node (here, btlog1) can, and probably will, change from one session to the next.

      2. The “~” indicates that you are in your home folder on the storage system.
