= Transfering data to and from the cluster = This is a distilled version of what is available here: https://scitas-data.epfl.ch/confluence/display/DOC/Data+Transfer+Nodes == Some background == There are two locations where you can place data on the SCITAS clusters 1. Your `home` directory 2. Your `scratch` directory The `home` directory is for your configuration files, your virtual environments, anything permanent you need to run what you need The `scratch` directory is volatile, meaning it can go down anytime, but it is for large data, so your individual projects, datasets and results should go here and be transfered back to your lab share at the end of processing. Moving data back and forth means connecting to the SCITAS Transfer nodes. Multiple solutions exist, but Oli has opted for WinSCP, as it has a GUI that makes transferring from Windows machines more comfortable. == First time setup == You **CANNOT** login using your username and password. You need to use public key authentication. Download and install [[ https://winscp.net/eng/index.php | WinSCP ]] === Create a private-public key pair === Open WinSCP and create a new site: ``` File protocol: SCP Host name: fdata1.epfl.ch User name: **your user name** ``` # Click on {nav Advanced > Authentication (Under SSH) > Tools > type=instructions, name=Generate New Key Pair with PuTTYGen} # Click on {nav Generate} and follow the instructions to add randomness. # Add a Key comment like "SCITAS Cluster Key" # Add a passphrase if you want # Click on {nav Save Private Key} and save it under `C:\Users\username\.ssh` as `scitas_access.ppk` # (Optional) Click on {Save Public Key} and save it somewhere else if you want as `scitas_access.pub` (it is not needed as such for this protocol) # Close PuTTYGen and back to WinSCP browse to your private key file # Click on {nav Display Public Key} and copy it to your clipboard # Open a command prompt and ssh into izar : `ssh izar.epfl.ch -l username` # Create a `.ssh` folder: `mkdir .ssh` # Change the permissions: `chmod 700 .ssh` # Paste your public key inside: `cho 'PASTE_FROM_CLIPBOARD' >> .ssh/authorized_keys` # Back to WinSCP, Save the Site as 'SCITAS fdata1` **Now you should be able to connect from WinSCP** NOTE: If you added a passphrase, you will need to provide it now.
