First of all, you probably don’t need this as your home, work, scratch (on Gaia) and project directories are shared across the cluster (but not between Gaia and Chaos clusters) such that copying files is usually not required.

Yet if for some reason you need to transfer files between reserved resources (for instance in the /tmp directory of one of the nodes from a different node reserved in the same job), you should use the specific OAR tool oarcp. Example on the Chaos cluster:

[21:07:20] login@k-cluster1-09 ~> hostname > /tmp/myhostname
[21:09:13] login@k-cluster1-09 ~> oarcp /tmp/myhostname node-14:/tmp/
myhostname                                100%   14     0.0KB/s   00:00
[21:09:15] login@k-cluster1-09 ~>
