====== Using Globus on DARWIN ======
===== Overview =====
Unlike Globus on the Caviness cluster, Globus on the DARWIN cluster does not require a staging area and features two distinct collections
* one for University of Delaware users ("**UD DARWIN Cluster - Home and Lustre**")
* one for ACCESS users ("**ACCESS UD DARWIN**").
There are no guest collections enabled on DARWIN.
===== Accessing the collection =====
Start by navigating to the [[http://app.globus.org/|Globus web application]] ([[http://app.globus.org/]]) in your web browser. If you have previously logged-in, you will be taken directly to the dashboard. Otherwise:
* Choose the **University of Delaware** as your organization and click the Continue button; on the next page enter your UDelNet Id and Password and continue on to the dashboard.
Click the “File Manager” button {{:software:globus:filemanagerbutton.jpg}} on the left side-panel. In the search box at the top of the page, enter "UD DARWIN" and click the magnifying glass icon:
{{:software:globus:darwin-filemanager.jpg}}
Depending on your account type, ACCESS or UD allocation, click on one of the corresponding collections, "**ACCESS UD DARWIN**" or "**UD DARWIN Cluster - Home and Lustre**"
Upon successful activation the collection, you should see the two primary directories listed: "home" and "lustre":

=== Getting files off DARWIN ===
* Files will be visible on your Globus endpoint, if they are in the "home" (''$HOME'') and "workgroup" (''$WORKDIR'') directories.
* For group projects, make sure files are located within the appropriate workgroup directory to ensure they are accessible by members of that workgroup via Globus.
=== Moving data to DARWIN ===
* Files copied to "home" (''$HOME'') or "workgroup" (''$WORKDIR'') directories via Globus will be directly accessible on the DARWINcluster.
**PLEASE BE AWARE** that all data moved to Darwin will be consuming storage space either on a user’s home or their group’s storage quota. Users are responsible for managing their data storage to avoid reaching capacity.
===== Finding your directories =====
You can find your uid number using the ''id'' command:
$ id -u
1001
Your directories can be found at ''/home/'' or ''/lustre//users/''.
