[https://www.globus.org/ Globus] is a service for fast, reliable, secure transfer of files. Designed specifically for researchers, Globus has an easy-to-use interface with background monitoring features that automate the management of file transfers between any two resources, whether they are at an Alliance cluster, another supercomputing facility, a campus cluster, lab server, desktop or laptop. | [https://www.globus.org/ Globus] is a service for fast, reliable, secure transfer of files.

Globus leverages GridFTP for its transfer protocol but shields the end user from complex and time consuming tasks related to GridFTP and other aspects of data movement. It improves transfer performance over GridFTP, rsync, scp, and sftp, by automatically tuning transfer settings, restarting interrupted transfers, and checking file integrity. | Globus leverages GridFTP for its transfer protocol but shields the end user from complex and time consuming tasks related to GridFTP and other aspects of data movement.

Globus transfers happen between "collections" (formerly known as "endpoints" in previous Globus versions). Most Alliance clusters have some standard collections set up for you to use. To transfer files to and from your computer, you need to create a collection for it. This requires a bit of setup initially, but once it has been done, transfers via Globus require little more than making sure the Globus Connect Personal software is running on your machine. More on this below under [[#Personal Computers|Personal Computers]]. | Globus transfers happen between "collections" (formerly known as "endpoints" in previous Globus versions).

You can start typing a collection name to select it. For example, if you want to transfer data to or from the Béluga cluster, type "beluga", wait two seconds for a list of matching sites to appear, and select <code>computecanada#beluga-dtn</code>. | You can start typing a collection name to select it.

You may be prompted to "authenticate" the collection, depending on which site is hosting the collection. For example, if you are activating a collection hosted on Graham, you will be asked for your Alliance username and password. The authentication of a collection remains valid for some time - typically one week for CC collections while personal collections do not expire. | You may be prompted to "authenticate" the collection, depending on which site is hosting the collection.

Once a collection has been activated you should see a list of directories and files. You can navigate these by double-clicking on directories and using the "up one folder" button. Highlight a file or directory that you want to transfer by single-clicking on it. Control-click to highlight multiple things. Then click one of the big blue buttons with white arrowheads to initiate the transfer. The transfer job will be given a unique id and will begin right away. You will receive an email when the transfer is complete. You can also monitor in-progress transfers and view details of completed transfers from the ["Activity" button](https://globus.computecanada.ca/activity) on the left hand side . | Once a collection has been activated you should see a list of directories and files.
