1. Whether you’re a UWyo faculty member (Principle Investigator; PI), a researcher or a student, you’ll start by creating a new project or by getting added to an existing project.

   1. If you’re a UWyo faculty member (PI), create a project here: Request an HPC research project

   2. If you’re a collaborative researcher/student, please contact the PI you’re working with and ask them to either:

      1. Request a project or

      2. Add you to an existing project.

      3. If UWyo is not your primary institution, please contact the UWyo faculty member you’re working with and have them Request an external collaborator account.

         1. After you get your external collaborator account, the PI will need to make a request to add your external collaborator account to a project (step ii).

         2. Be sure to ask the PI which HPC resource the project is associated with - ARCC has several.

2. While you wait to be associated with a project, please take some time to learn how to setup and use Two-factor authentication (2FA).

   1. If you plan to work from off campus, you’ll need to learn how to setup and use a VPN connection.

   2. Note: the process of becoming associated with a project, etc can take hours to days, depending on workload. Once the process is complete, you will receive an automatically generated email from arcc-admin@uwyo.edu (don’t email this address - it is not monitored).

3. Now you’re ready to connect/login to a cluster!

   1. Note: you need to not be connected to the UWguest wireless network.

   2. Open a terminal window or similar command line interface (CLI). Learn how.

   3. Type in “ssh <username>@<clustername>.arcc.uwyo.edu” and press enter.

      1. For example: ssh arccuser@teton.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.

         1. The Two-factor message may say something about entering your password in this form: <password, token>. This is no longer necessary, but still possible to do.

4. Once you are connected, a bunch of text will scroll by. This will vary depending on the cluster. On Teton, 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@tlog3 ~]$

      1. This shows your username and which login node you are currently utilizing. The login node (here, tlog3) 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.
