Karst Desktop at IU

On this page:


Overview

At Indiana University, Karst Desktop is a remote desktop service for users with accounts on the Karst research supercomputer. Karst Desktop lets you open and control a remote session on Karst from a graphical desktop window running on your personal computer. You can run graphical applications installed on Karst from your Karst Desktop window without noticeable latency. Additionally, you can export your computer's local drives and directories, making them available to you during your remote session, simplifying the transfer of data between your computer and your Karst account. Overall, Karst Desktop provides numerous features that are especially 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 interacting only with graphical user interfaces (GUIs), such as those in Windows or OS X, learning how to effectively use a Unix-like command-line interface can be a challenge (or even an impediment to your research). The Karst Desktop service is designed to help reduce the learning curve for users with little or no command-line experience and, as a result, promote broader use of IU's research supercomputers.

System information

To use the Karst Desktop service, you need an account on the Karst research supercomputer; if you don't already have an account, see Get additional IU computing accounts.

The Karst Desktop service is supported by more than a dozen dedicated nodes. Each node is equipped with two 8-core Intel Xeon E5-2650 v2 (2.60 GHz) processors and 256 GB of RAM.

Karst Desktop nodes are accessible only from ThinLinc Client connections. You cannot SSH directly to any of the Karst Desktop nodes from a terminal client on your workstation.

Access Karst Desktop

To use Karst Desktop, you need an account on Karst; for information about getting a Karst account, see Research system accounts (all campuses).

Once you have an account on Karst, you can use the ThinLinc Client remote desktop application available from IUware to access Karst Desktop. For instructions, see At IU, how do I configure ThinLinc Client to connect to Karst Desktop?
