SCIAMA
High Performance Compute Cluster
Exercise: Logging in to SCIAMA
Introduction
Using the ssh keys generated in the previous exercise log into the Sciama environment.
There are eight login servers. For the purpose of the exercises please only use:
- login4.sciama.icg.port.ac.uk
When you connect to Sciama you need to decide whether you are going to work from a command line or whether you need to be able to display graphical user interfaces (GUIs) from applications running on Sciama. These two modes are called:
- Terminal mode (e.g. ssh)
- Graphical mode (e.g. ssh + X-forwarding, X2Go)
The article on both modes can be found HERE.
Exercise
Log-in to your designated Login sever. You can use either terminal or windows mode.
Once logged in copy the training material into your $HOME area and unpack. Use the following commands in a terminal:
- cd $HOME
- cp /opt/apps/training/training.tar.gz $HOME
- tar xvf training.tar.gz
- cd training
- ls
The output of ls should display a number of files and folders.
NB: information on any Linux command can be found in the manual pages. Use the “man” command on the command line:
- man <command>
The training directory contains a number of sub directories:
- src – contains example source code.
- logs – will contain the log files of any jobs run.
- bin – will contain an executables created.
- scripts – will contain example job scripts.
