Login

To access the TIPCC cluster you need an account - any UCSF Cancer Center affiliate can get an account. Anyone with a TIPCC account, can access the cluster via Secure Shell (SSH). Since access is restricted to computers on the UCSF network, make sure you are first connected via the UCSF VPN, if you are outside.

Instructions

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

  1. Open a terminal (called ‘Terminal’ on macOS and most Linux distributions),

  2. at the terminal prompt, type ssh alice@cclc01.som.ucsf.edu and press ENTER, and
  3. when prompted, enter your TIPCC password.

Example

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

{local}$ ssh alice@cclc01.som.ucsf.edu
alice1@169.230.134.141\'s password: XXXXXXXXXXXXXXXXXXX
[alice@cclc01 ~]$

If you get Permission denied, please try again. when you enter your password, make sure you use the correct TIPCC 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 TIPCC, type exit or logout (standard Unix commands) and press ENTER. For example,

[alice@cclc01 ~]$ exit
Connection to cclc01.som.ucsf.edu closed.
{local}$

An alternative is to press Ctrl-D (signals “QUIT”) at the command-line prompt.
