The typical way to access the HPC resources is through ssh (Secure Shell). You will need an ssh client on your laptop/workstation. If your workstation is a Linux or Mac system then you already have what you need. Simply open a terminal session and initiate an ssh session. If you have a Windows machine then you will have to obtain an ssh client. There are a couple of options but the recommended one is SecureCRT, which is licensed by the University of Iowa.
If you are on campus or connected to the University of Iowa VPN then you can access the HPC systems as follows:
...
on campus or off campus with VPN
| Code Block |
|---|
ssh argon.hpc.uiowa.edu |
Since the standard port for ssh is often used to attempt to break into systems, an alternate port is used if you are off-campus and not connected to the VPN.
...
off campus without VPN
| Code Block |
|---|
ssh -p 40 argon.hpc.uiowa.edu |
If you are connecting from a computer where you are not logged in with your HawkID then you will have to specify the HawkID as the ssh client will try to login with the user name on the machine you are on. To do that, prepend your HawkID to the system name.
...
specifying username for ssh
| Code Block |
|---|
ssh -p 40 HawkID@argon.hpc.uiowa.edu |
If on a Windows machine enter the appropriate values in the configuration fields of the client application. When you receive a password prompt enter your HawkID password. If all went well you should then be logged on to the selected HPC system.

The above may be useful if you need to reconnect back to the same login node for some reason.
