Research Desktop (RED) at IU

Overview

Important:

To use Research Desktop (RED), you need the following:

Research Desktop (RED) is a graphical desktop service for users with accounts on the Carbonate research supercomputer at Indiana University. UITS developed RED to be particularly helpful to users who are unaccustomed to working in Unix-like command-line environments. Most research supercomputers, including those at IU, run Unix-like operating systems that, by default, require you to type commands into a command processor, or shell. If you are accustomed to working only with graphical user interfaces (GUIs), such as those in Windows and macOS, learning how to effectively use a Unix-like, command-line interface can be a challenge (or even an impediment to your research). RED helps reduce the learning curve for users with little or no command-line experience and, as a result, promotes broader use of IU's research cyberinfrastructure.

RED lets you use a graphical user interface (GUI) running on your personal device to launch and control a session running on one of more than two dozen dedicated nodes, each equipped with either two 8-core or two 12-core Intel Xeon processors and 256 GB of RAM. From the RED GUI, you can run graphical applications remotely without noticeable latency and without needing to submit an interactive compute job.

By default, RED provides access to your scratch and/or project space on the Data Capacitor II (DC2) high-performance file system, and your home directory space (for example, /N/u/your_username) on IU's research computing systems. Advanced options let you export local resources to your RED session, enabling data transfers between your personal device and your research computing accounts. Secure shell (SSH) encryption is used to protect data traffic between your personal device and your RED session.

For more, see Research Desktop (RED) usage policies and interface features.

Access RED

Once you have an account on Carbonate and a device enrolled in IU's Duo two-step login service, you can use the ThinLinc Client remote desktop application available from IUware to access RED. For instructions, see Download, install, and configure ThinLinc Client to use Research Desktop (RED) at IU.

Alternatively, you can use a web browser to access https://red.uits.iu.edu. If prompted, use your IU username and passphrase to authenticate via IU Login (formerly CAS), and then confirm your identity using Two-Step Login (Duo).

Note:
  • SSH public-key authentication (PKA) is supported for connections made with the ThinLinc Client. (The web interface does not support SSH PKA.) For help with SSH key pairs, see Set up SSH public-key authentication to connect to a remote system.
  • To access files on your personal device from within your RED session, you must connect using the ThinLinc Client remote desktop application. (The web interface does not support exporting local drives and directories.)
  • You cannot use a terminal client to SSH directly to any of RED's dedicated nodes.
