What is FastX?

FastX displays your remote Linux desktops faster than regular X Windows emulator, especially over Internet connections. It is an easy-to-use client-served based X11 emulator, that allows you to connect to a remote Linux server using any browser (Firefox, Chrome, Internet Explorer or Safari). FastX offers productive user experience over long distance and low bandwidth connections.

FastX connections are persistent, you can reconnect to your session after a network failure or unplanned reboot of your workstation. Users can also suspend their sessions, disconnect their PC and resume the session at a later time from any device.

Why should I use FastX?

FastX has the primary purpose of providing a graphical interface to our servers on slow connections from off-campus. Users should be able to easily access to debug tools like Allinea, data visualization tools like Paraview, feature rich IDEs like Eclipse and numerous GUI scientific apps (Matlab, Stata, etc...) on CRC frontends.
