Globus

Globus is a tool for sharing large quantities of data across different systems, ranging from your laptop to HPC systems both within and without NOAA to the cloud. As such, it is a great tool for sharing model output with collaborators who may not have access to GFDL systems, as well as getting data from colloborators, or simply moving it between machines. This page list steps for using Globus on several GFDL systems:

Accessing Globus

Assuming you have a NOAA RDHPCS account

1. Click log in on the Globus home page
2. In the list of available organizations, search for NOAA RDHPCS
3. Log in with your NOAA email and RSA+PIN

Sharing data from PPAN

The recommended way to share data from PPAN is to create a Globus guest collection that you can share with collaborators who also have Globus accounts:

1. On the left hand side of the Globus Home page, click on the File Manager
2. You should see a screen with two search bars at the top labeled "Collections", two text entry fields name "Paths", and two blank panels below this. If you don not see this screen, select the "set two pane" in the top right corner of the screen
3. In the panel on the left hand side, search for "noaardhpcs$ppan_untrusted" in the collections bar, and select the option that appears on the screen
4. This will return you to the screen with the two panels. In the panel on the right hand side, select "share"
5. This will bring you to a screen titled "Guest Collections". In the top right hand side, select "Add Guest Collection"
6. Select your name from the drop down menu labelled "Directory" If you do not see your name, you will have to create a directory in /collab1/data_untrusted/${USER} to share data. Note that this is the only location you can share data from on PPAN
7. Give this directory a name and a description, then hit "Create Collection"
8. You will then be brought to a screen labelled "Shared With". Click the "Add Permissions - Share with" button in the top right corner to share this collection with a collaborator. All you have to do is enter their Globus username/email and click "Add permission"

You collaborator should now be able to view any files or directories you place in /collab1/data_untrusted/${USER}.
