I need to use the local scratch area, may I? How? Is it backed up?

Generally each linux workstation should have a local disk area called “ /scratch
You can write your data here.
Put your files in /scratch/yourusername directory and NOT in /scratch. Therefore, firstly you have to create a subdirectory in the /scratch directory using the following command from a linux shell:
mkdir /scratch/yourusername

Do not put important files in scratch areas, because if the local disk is damaged, we will not be able to recover its contents.
Local directories (for example: /scratch /data /tmp) are never saved (“ backed up ”)!!

For I/O intensive applications (i.e. huge data on input/output files), you are strongly suggested to use the local disk of the workstation where your executable is running and NOT your home directory. Since the latter is accessed by the workstation through the network, the reading and writing procedure could slow down terribly and lower the performance of your application.

You can not access to workstations local scratch areas from outside SISSA through the server ssh.sissa.it
vpnimage Please note, there is a NEWS. From the external network you can reach your linux workstation and so reach its /scratch area using the VPN connection.
To use the VPN connection, you should install the VPN client on your laptop, so please read the information on Cisco VPN client installation page.
