HOWTO: Use Globus (Overview)



Globus is a cloud-based service designed to let users move, share, and discover research data via a single interface, regardless of its location or number of files or size.

Globus was developed and is maintained at the University of Chicago and is used extensively at supercomputer centers and major research facilities.

Globus is available as a free service that any user can access. More on how Globus works can be found on the Globus "How It Works" page.

Data Transfer

Globus can be used to transfer data between source and destination systems including OSC storage, cloud storage, storage at other HPC centers with Globus support, laptops, desktops. 

If you would like to transfer data between OSC storage and your own laptop/desktop which has not installed Globus Connect Personal yet, please go to 'Globus Connect Personal Installation' first

Step 1: Log into Globus

Log into

When prompted to login, select "Ohio Supercomputer Center (OSC)" from the drop-down list of organizations and then click Continue. This will redirect you to the Ohio Supercomputer Center login page where you can log in with your OSC username and password.

Step 2: Locate collections of your data

Click 'File Manager' on the left of the page. Switch to 'two panel' view by click icons next to 'Panels'. One panel will act as the source while the other is the destination. 

Click 'Collection' to search the collection of your data.

For OSC storage, use 'OSC endpoints' information to locate the collection. 

Step 3: Transfer the file

Select the file(s) or directory that you would like to transfer between collections. You can now select the "Transfer or Sync to..." and hit the blue "Start" icon above the file selector.

Step 4: Verfiy the transfer 

Click Activity in the command menu on the left of the page to go to the Activity page.

Globus Connect Personal Installation

Globus Installation on Windows

  1. Download Globus Connect Personal.

  2. Launch the application installer.

  3. If you have local administrator permissions on your machine, and will be the only user, click on 'Install'.

    • If you do not have local administrator permissions or wish to specify a non-default destination directory for installation, or will have multiple GCP users, click on the 'Browse' button and select a directory which you have read/write access to.
  4. After installation has completed GCP will launch. Click on 'Log In' in order to authenticate with Globus and begin the Collection Setup process.

  5. Grant the required consents to GCP Setup.

  6. Enter the details for your GCP Collection.

  7. Exit the Setup process or open the Globus web app to view collection details or move data to or from your collection.

  8. At the end of the installation, you will see an icon in the menu bar at the bottom of your screen, indicating that Globus Connect Personal is running and your new collection is ready to be used.

OSC endpoints

  • Enter 'OSC Globus Connect Server' in the endpoint search box to find all the endpointss managed by OSC as below:
OSC's home directory OSC $HOME
OSC's project directory OSC /fs/project
OSC's scratch directory OSC /fs/scratch
OSC's ess storage OSC /fs/ess
AWS S3 storage OSC S3
OSC high assurance

OSC /fs/ess/ High Assurance for project storage

OSC /fs/scratch/ High Assurance for scratch storage

Note: the default path will be $HOME for home directory, /fs/ess for project storage, /fs/scratch for scratch filesystem. You can change to a more specific directory by providing the path in ‘Directory’. The location for project/scratch data would be under /fs/ess/<project-code> or /fs/scratch/<project-code>.

Data Sharing

With Globus, you can easily share research data with your collaborators. You don’t need to create accounts on the server(s) where your data is stored. You can share data with anyone using their identity or their email address.

To share data, you’ll create a guest collection and grant your collaborators access as described in the instructions below. If you like, you can designate other Globus users as "access managers" for the guest collection, allowing them to grant or revoke access privileges for other Globus users.

  1. Log into Globus and navigate to the File Manager.

  2. Select the collection that has the files/folders you wish to share and, if necessary, activate the collection.

  3. Highlight the folder that you would like to share and Click Share in the right command pane.

    Note: Sharing is available for folders. Individual files can only be shared by sharing the folder that contains them. If you are using an ad blocker plugin in your browser, the share button may be unavailable. We recommend users whitelist,, and within the plugin to circumvent this issue.

    If Share is not available, contact the endpoint’s administrator or refer to Globus Connect Server Installation Guide for instructions on enabling sharing. If you’re a using a Globus Connect Personal endpoint and you’re a Globus Plus user, enable sharing by opening the Preferences for Globus Connect Personal, clicking the Access tab, and checking the Sharable box.

  4. Provide a name for the guest collection, and click Create Share. If this is the first time you are accessing the collection, you may need to authenticate and consent to allow Globus services to manage your collections on your behalf.

  5. When your collection is created, you’ll be taken to the Sharing tab, where you can set permissions. The starting permissions give read and write access (and the Administrator role) to the person who created the collection.

    Click the Add Permissions button or icon to share access with others. You can add permissions for an individual user, for a group, or for all logged-in users. In the Identity/E-mail field, type a person’s name or username (if user is selected) or a group name (if group is selected) and press Enter. Globus will display matching identities. Pick from the list. If the user hasn’t used Globus before or you only have an email address, enter the email address and click Add.

    Note: Granting write access to a folder allows users to modify and delete files and folders within the folder.

    You can add permissions to subfolders by entering a path in the Path field.

  6. After receiving the email notification, your colleague can click on the link to log into Globus and access the guest collection.

  7. You can allow others to manage the permissions for a collection you create. Use the Roles tab to manage roles for other users. You can assign roles to individual users or to groups. The default is for the person who created the collection to have the Administrator role.

    The Access Manager role grants the ability to manage permissions for a collection. (Users with this role automatically have read/write access for the collection.) 

    When a role is assigned to a group, all members of the group have the assigned role.

Data Sharing with Service Account

Sometimes, a group may need to share data uploaded by several OSC users with external entities using Globus. To simplify this process OSC can help set up a service account that owns the data and create a Globus share that makes the data accessible to individuals. Contact OSC Help for this service.
