Transferring Data

This document shows how to transfer data between PSI and CSCS by using a Linux workstation.

Preparing SSH configuration

If the directory .ssh does not exist in your home directory, create it with 0700 permissions:

Bash
mkdir ~/.ssh
chmod 0700 ~/.ssh

Then, if it does not exist, create a new file .ssh/config, otherwise add the following lines to the already existing file, by replacing $cscs_accountname by your CSCS username:

Bash
Host daint.cscs.ch
  Compression yes
  ProxyJump ela.cscs.ch
Host *.cscs.ch
  User $cscs_accountname

Advanced SSH configuration

There are many different SSH settings available which would allow advanced configurations. Users may have some configurations already present, therefore would need to adapt it accordingly.

Transferring files

Once the above configuration is set, then try to rsync from Merlin to CSCS, on any direction:

Bash
# CSCS -> PSI
rsync -azv daint.cscs.ch:<source_path> <destination_path>

# PSI  -> CSCS
rsync -azv <source_path> daint.cscs.ch:<destination_path>
