In client-server mode, you start VisIt locally, on your desktop/laptop and then use VisIt to log into and launch VisIt's metadata server and engine components on remote resources.Īlthough client-server is the preferred way of using VisIt in general to access remote resources and although it also works around disabled INdirect GLX rendering in your local X server, there are many reasons users may still want to run VisIt entirely remotely and display back to their desktop via X.
