Note: you need to not be connected to the UWguest wireless network.
Login may be done through a number of different methods but most commonly will be performed through Command Line Interface. Learn how.
Once in a command line interface, type in “ssh <username>@<clustername>.arcc.uwyo.edu” and press enter.
For example: ssh email@example.com
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?’.
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.
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.
Note that when you are logged in, the command prompt will look something like this: [arccuser@btlog1 ~]$
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.
The “~” indicates that you are in your home folder on the storage system.
ARCC uses the Slurm Workload Manager to regulate and schedule user submitted jobs and tasks on our HPC systems. If you’re running a job on an ARCC HPC system, Slurm is likely managing resources for it to run. Read more about processing jobs and using slurm here.
LMOD is very useful software on a HPC cluster that is leveraged to maintain a number of dynamic user environments and allow users to switch between software stacks and packages on HPC resources. Learn more about using LMOD here.
