- Start the Mobaxterm application and open a local terminal
- Login to the RACC using
ssh -X cluster.act.rdg.ac.uk On the cluster type the command: ssh troifsX@ecaccess.ecmwf.int Note: Instead of troifsX you should use your ECMWF training user-ID - You will be prompted for the hostname with a choice between
ecgate , cca and ccb . You should select ccb . - When you have completed your work you can disconnect from
ccb by typing exit at the command prompt.

- After the first login type the following command:
/home/ectrain/troifs0/setup-cray/my43 - Log out of the training account by typing
exit Login once more using ssh troifsX@ecaccess.ecmwf.int - Type the following command:
get43

The actions above will ensure that your training account receives required scripts and shell configuration files.
The last command will copy the model binaries and input files to your account for version 43r3.
Instead of using the login nodes of the HPCF we will use an interactive session to ask for computing resources and fast temporary disk. This also allows to run parallel jobs in the terminal window.
