Using X Windows
X-Windows allows you to display remote applications on your local computer screen. X-Windows follows the client-server architecture. Normally, the X server runs on the users desktop/laptop computer, while the X client (for example a GUI application) runs on the remote server. The X Client displays itself on the X Server.
Using NERSC NX Service to Improve X Performance
NX is a computer program that handles remote X Window System connections. It can greatly improve the performance of the X Windows, to the point that it can be usable over a slow link such as a dial-up modem. NX also provides sessions, which will allow a user to disconnect from the session and reconnect to it at a later time, while keeping the state of all running applications inside the session. This gives users a virtual desktop that's running at NERSC.
For more information about NERSC NX Service, please refer to the NX Documentation Page.
Using X-Windows on Unix-like Systems (Mac OSX, Solaris, Linux, etc)
Most Unix-like systems have X server installed by default. The user only need to provide the -X option when starting an SSH connection:
% ssh -X firstname.lastname@example.org
Using X-Windows on Windows PC
We suggest users to use the NX service for easier and faster X windows experience. For more information about NERSC NX Service, please refer to the NX Documentation Page.
To use X-Windows on a windows PC without using NX you'll need to install an X Server on your PC, and use an SSH client with X-Windows forwarding to connect to NERSC.
