If you need to move a large volume of data, you can do so using a Globus endpoint. The system uses Globus for high performance transfer of large files. Endpoints represent locations on a file transfer service server, such as gridftp. A prerequisite is a GCSv4 Share.
To prepare a Globus endpoint:
- Log into Globus at the following site:
http://www.globus.org
Use your user account credentials as described in the following page:
https://docs.globus.org/how-to/get-started/ If you do not already have a GCSv4 Share in Globus, create one:
- In the Globus File Manager, search for and select NIH HPC Data Transfer (Biowulf). This is a public endpoint.
- In the search results, in the row for NIH HPC Data Transfer (Biowulf), click the collection details icon (
). The details page appears. On the Collections tab, click Add GCSv4 Share. 
- On the Create new GCSv4 Share page, browse to or specify the path to the directory where you want to save your data. Click Create GCSv4 Share.
- In the Globus File Manager, search for and select NIH HPC Data Transfer (Biowulf). This is a public endpoint.
- Share your Globus endpoint:
In the Globus File Manager, navigate to the list of collections by opening the side bar, clicking Collections, and then clicking Shareable by You.
Select your GCSv4 Share. Access the sharing configuration for that collection by clicking Permissions.
Add permissions by clicking Add Permissions - Share With. In the Share With field, select the option to share with a group. Click Select a Group.
Search all groups for "MODAC" and select MODAC-PROD-App-Accts-Pool-NCI_DOE.
- Select the appropriate permission for the selected group: If you intend to download data to the Globus endpoint, select the write permission.
- Click Add Permission. The system adds the MODAC-PROD-App-Accts-Pool-NCI_DOE Globus group to the list for the current share.
Now you can upload or download data as described in the following pages:
