NERSC NX Service - X-Windows Acceleration at NERSC
NX is a computer program that handles remote X Window System connections and it provides three benefits for NERSC users:
- SPEED: NX can greatly improve the performance of X Windows, allowing users with slow, high latency connections (e.g. on cell phone network, traveling in Africa) to use complex X Windows programs (such as rotating a plot in Matlab).
- SESSION: NX provides sessions that 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.
- DESKTOP: NX gives users a virtual desktop that's running at NERSC. You can customize the desktop according to your work requirement.
The NX Service
The new NX uses KDE as the default desktop. KDE provides a friendly and highly customizable user interface. NERSC has made NX available to all active users. If you can log in to a NERSC system you can connect via NX with your NERSC username and password.
Quick Start Up Tutorial
Connecting to NX
You can connect to NX via the NX Client or by pointing your browser at https://nxcloud01.nersc.gov:4443. The browser interface is still experimental and can sometimes be slower than connecting via the client. Please let us know by opening a ticket if you encounter any issues with it.
