Transferring files to and from the cluster

It may be necessary at times to transfer files from a local computer to the HPC cluster, or vice versa.  This article will provide instructions on how to do so, focusing primarily on Windows users who connect via Secure Shell or MobaXterm.

Linux/Mac users who access SeaWulf or LI-red via a terminal program can transfer files back and forth using either sftp or scp command line functions.  Example syntax for scp can be found here, while sftp examples can be found here.  

 

For Windows users who connect via the SSH utility, files can be transfered using the separate SSH Secure File Transfer application.  After opening this utility, click the connect button, and input the appropriate hostname and your username, followed by your password:

Once you are connected, you will see the contents of your SeaWulf or LI-red Home directory on the right side of the screen, while your local file system is shown on the left.  To transfer a file from your local machine to the cluster, choose where you would like to place it by navigating to the appropriate directory on the right side of the screen:

Then, simply navigate to the local directory containing your file on the left side of the screen, and drag the file from the left side to the right side of the screen.   

To download a file from the cluster to your local machine, do the opposite.  Navigate to the destination directory on the left, navigate to the file on the right, and drag it from right to left. 

 

For MobaXterm users, the process is similar.  After starting MobaXterm, select "New Session", and choose "SFTP":

After providing your login information, you will see your local file system on the left, while your home directory on the cluster is shown on the right:

As before, to transfer files back and forth, simply navigate to the appropriate local and remote directories on each side of the screen, and then drag and drop.
