Command Line Interface (CLI)

On most HPC clusters, users access the system via a text-based command line interface (CLI). Typically, command line access is provided via an encrypted, secure shell (SSH). The command line provides a powerful and flexible interface into the cluster - though there is a learning curve.

Mac and Linux computers include built-in support for the command line. Windows computers are supported, too, although a shell client program must be installed.

Graphical Interface (GUI)

It is also possible to access the cluster via a GUI. The GUI provides a more familiar interface to beginners. It also allows usage of advanced tools, such as graphical debuggers and performance profilers.

Microway recommends NoMachine for responsive, enterprise-class GUI connections to clusters. Some HPC administrators may also configure VNC, Remote Desktop, X-Win32, or X-Windows tunneling through SSH connections.

The following sections describe the various ways to login to our Test Drive cluster.
