Login #

To access the Wynton HPC cluster you need an account - any UCSF affiliate can get an account. Anyone with a Wynton HPC account, can access the cluster via Secure Shell (SSH).

Prerequisites #

The instructions below requires that you:

Users on Linux, macOS, and MS Windows have an SSH client built-in, which is available from the terminal as ssh. We will use that one in all our examples. You can also use other SSH clients if you prefer, include PuTTY on MS Windows. If you choose to use another SSH client, consult that program’s documentation for further instructions. Another alternative, which some might find easier, is to connect to the cluster using the X2Go software.

Instructions #

To log into the cluster, assuming your user name on Wynton HPC is alice (case sensitive), do the following:

  1. For first-timers outside of the UCSF network, log onto the UCSF VPN,

  2. open a terminal (‘Terminal’ on macOS and most Linux distributions, and ‘Windows Console’ [old] or ‘Windows Terminal’ [modern] on MS Windows),

  3. at the terminal prompt, type ssh alice@log1.wynton.ucsf.edu and press ENTER, and

  4. when prompted, enter your Wynton HPC password.

Example #

When logging in from your local computer, you should see something like:

{local}$ ssh alice@log1.wynton.ucsf.edu
alice@log1.wynton.ucsf.edu:s password: 
[alice@log1 ~]$ 

Note, when typing your password, there will be no visual feedback at all, but the system will still receive what you type, so just press ENTER afterward.

If you get Permission denied, please try again. when you enter your password, make sure you use the correct Wynton HPC username (case sensitive) and the correct password.

What is available on the login node? #

The login node is dedicated solely to very basic tasks such as copying and moving files on the shared file system, submitting jobs, and checking the status on existing jobs. Note that most software tools are not available on the login node, which means you can neither use it for prototyping scripts nor build software. Instead, for such tasks, use a development node, which is configured identically to the compute nodes.

Logout #

Like for all Unix-based system, to log out from Wynton HPC, type exit or logout (standard Unix commands) and press ENTER. For example,

[alice@log1 ~]$ exit
Connection to log1.wynton.ucsf.edu closed.

An alternative is to press Ctrl-D (sends “End-Of-File” [EOF]) at the command-line prompt.
