Display graphical output

To display simple graphical output, such as PDF, JPEG, or PNG files, connect to Helix or Biowulf using X11. For running application GUIs or more advanced graphical displays, use either NX or FastX as your X11 server.

Transfer Files

To process data on the NIH HPC systems, the data needs to reside on the /home or /data areas. If your data is on your local desktop or server, it will need to be transferred to the NIH HPC systems. There are several methods such as GUI file transfer clients, scriptable commandlines, and Globus available for file transfer. See the file transfer page for details.

Request more Disk Space

Fill out the form at https://hpc.nih.gov/dashboard/storage_request.php. You can only request a quota increase for your own /data area or for a shared area where you are the group owner.

If you need a new group area where members of your group can all read and write files, fill out the form at https://hpc.nih.gov/dashboard/shared_data_request.php.

Share Data

There are several options for sharing data, depending on whether you want to share one-time, occasionally, or regularly, and depending on whether you want to share with an HPC user, a collaborator at NIH or a collaborator outside NIH. See the Sharing Data page for details.

Make Changes to a Group

Fill out the form at https://hpc.nih.gov/dashboard/group_change.php. Only group owners are allowed to make changes to a group.

Deal with File Permissions

Understand how Linux permissions allow or deny access to files, and how to determine and change permissions is described on the Managing Access Permissions page.
