Transfering files to and from cluster

There are few ways to transfer data in and out:

• Directly with sftp/scp
• mounting directory from cluster to your workstation with sshfs
• accessing TUNI intra directory directly from cluster

From Linux-machine

SCP/SFTP

You can copy your files to narvi-cluster with command scp that does not need any mounts.

For example copy one file from localhost to narvi .. code-block:

scp yourfile narvi:/home/${USER}

Copy a directory from localhost to narvi .. code-block:

% scp -r yourdirectory narvi:/home/${USER}

You can use this also to other direction or between any other two hosts.

For more information .. code-block:

man scp

SSHFS

You can mount your homedirectory from narvi-cluster to your localhost with command sshfs.

First create a directory where you mount your home from narvi .. code-block:

mkdir ${HOME}/narvi-home

Then use sshfs to mount your narvi-home to directory you just created

This example asumes that your home in narvi is /home/$USER, if it is not that please change to correct one .. code-block:

sshfs ${USER}@narvi.tut.fi:/home/${USER} ${HOME}/narvi-home

When file transfers are ready and you don’t need to have this mount, unmount narvi-home from your localmachine with command .. code-block:

fusermount -u ${HOME}/narvi-home

For more information

man sshfs man fusermount

From Windows-machine

Moving files between your windows-machine and cluster might be easiest with WinSCP after you add you private-key to it.

Or then you should have your files on your INTRA -homedirectory so you access them directly on cluster frontend:

TUNI home&group -directories

You can access your TUNI-home and group directories directly on frontend nodes (narvi and narvi-shell):

/tuni/groups directory contains all group directories which you have access, but you’ll have to now the specific directory’s name. So unless you have visited some directory /tuni/groups will be empty.
