File transfer

Access to the systems (Betzy, Fram, Saga, NIRD) is permitted only trough secure shell (ssh). One can use scp (secure copy) or sftp (secure file transfer protocol) to upload or download data. There are graphical frontends for these tools, for instance WinSCP for MS Windows.

To transfer files between an HPC cluster (Betzy, Fram or Saga) and NIRD, one can use regular cp or mv commands on the cluster login nodes to copy or move files into or out of the NIRD project areas, since these are mounted on the cluster login nodes. For more information, please check out the Betzy, Fram and Saga storage page.

scp: secure copy between hosts on a network

# copy single file to home folder on Fram
# note that folder is ommitted, home folder being default
scp my_file.tar.gz <username>

# copy a directory to work area
scp -r my_dir/ <username><username>/

# copy a result directory back to my laptop
scp -r <username><username>/my_results /home/some/place

sftp: interactive secure file transfer program (Secure FTP)

# copy all logs named starting with "out" from project1 folder to
# /nird/projects/project1 on NIRD
sftp <username>
sftp> lcd project1
sftp> cd /nird/projects/project1
sftp> put out*.log
