Connecting to the cluster
If you don't already have an account, please fill out the cluster application form.
SSH access
To access the cluster resources and send commands you need to use an SSH client. On Mac and Linux, from the a terminal simply run:
ssh Your_NetID@login.storrs.hpc.uconn.edu
(Where 'Your_NetID' is your own NetID consisting of 3 letters and 5 numbers)
For Linux/MacOSX users, it is recommended to set up and use SSH keys.
Windows users can login using PuTTY.
Once connected, you should see a terminal prompt like:
[Your Net ID@cn01 ~]$
Off-campus Access
SSH connections are limited to on-campus addresses from both the wired network and the "UCONN-SECURE" wireless network.
In order to connect to HPC from off campus, you will first need to connect to the VPN: The UConn VPN is the recommended way to access the Storrs HPC cluster from off campus. Windows and Mac users should follow the instructions on that page for installing the VPN client. Linux users should follow these alternate instructions.
Submitting Jobs
All job submission, management, and scheduling is done using the job scheduler software SLURM. To learn more about job submission and management, please read our SLURM Guide.
Always run jobs via SLURM. If you do not, your process may be throttled or terminated.
Please read our usage policy for more details.
Standard Cluster Nodes
There are four classes of nodes available on the HPC cluster, each named after the Intel CPU architecture, listed in the table below.
