Transferring data from the Shared Cluster (GHPCC) to Unity:

This guide will allow you to transfer data from the Shared Cluster (GHPCC) to Unity via Globus.

Step 1: Log in to Globus

Step 2: Connect to the Shared Cluster and Unity

  • Select the File Manager tab from lefthand pane
  • In the two "Collection" boxes, select the Shared Cluster and Unity via their Globus identities
    • The Shared Cluster is ghpcc#ghpcc07
    • Unity is Unity
      • more technical identifier: acda5457-9c06-4564-8375-260ba428f22a
    • If you start typing either in the "Collection" text box, the drop-down will update and allow you to select the appropriate "Collection" (aka cluster)
  • Provide your login credentials for each cluster
    • Once you're finished logging in to each connection, the screen should look something like this:

Step 3: Transfer files

  • Below, the Connection and Path text boxes, you should see the contents of each directory.
  • Navigate to the location of the file/directory you'd like to transfer from and to.
  • Select the file/directory you'd like to transfer
  • Click on the "Transfer or Sync to..." button. Shown in the middle here:
  • Voila! The file/directory will be queued up and transferred shortly!

Step 4: Confirm that transfer was successful

  • You'll receive an email once the transfer occurs.
  • Open the Destination directory and confirm that the file was transferred as expected.

This guide will allow you to send data from the Shared Cluster to the Unity server using scp for the purposes of transitioning.


  • You will need to have set up an account on the Unity server.
  • You will need your password for the Shared Cluster server (unless you are using private/public keys for logging on to this too).

Step 1.

  • Log in to the Shared Cluster (GHPCC).
  • While logged into the Shared Cluster, from your home directory, run ssh-keygen -t rsa
    • This will generate a private/public key pair which is unique to each user.
    • The generator will ask you to save the keys as a specific name, and you have the option to associate a password to the keys (recommended but not required).
    • Two files will be created: NAME and
    • is the public key that you will need for Step 2.

Step 2.

  • Log in to the Unity cluster portal:
  • Navigate to "Account Settings"
  • You will see the SSH keys that are currently linked to your account
  • Click the "+" button to add the Shared Cluster key to your account.
  • Copy the entire contents of the public key ( from the Shared Cluster generated in Step 1 into the prompt.
  • Click "add key"
  • Click "Set Login Shell"
    • This will now link the two servers, allowing them to communicate

Step 3.

  • Log into the Unity cluster
  • Create a file to test the connection between servers (e.g. touch test.txt)
  • Attempt to transfer the file from Unity to the Shared Cluster:
    • scp test.txt
  • You will be prompted for your password to the Shared Cluster - enter it here.
  • If configured properly, this file should transfer immediately to the specified destination path (in this case /home/username/)

Step 4.

  • Assuming that Step 3 worked and the file transferred across from Unity to the Shared Cluster, you can use this to pull data across: scp* ./destination/
  • Each time you run scp in this way, you will be prompted for your password.
  • Note that currently this only works when logged in and running commands from Unity, not the Shared Cluster.
