When you run VisIt locally, you usually select files, open a database, and create plots using the open database. Fortunately, the procedure for running VisIt in distributed mode is no different than it is for running in single-computer mode. You begin by opening the File Selection Window and typing the name of the computer where the files are stored into the Host text field.
Once you have told VisIt which host to use when accessing files, VisIt launches the VisIt Component Launcher (VCL) on the remote computer. The VCL is a VisIt component that runs on remote computers and is responsible for launching other VisIt components such as the database server and compute engine (figure). Once you are connected to the remote computer and VCL is running, you won't have to enter a password again for the remote computer because VCL stays active for the life of your VisIt session and it takes care of launching VisIt components on the remote computer.
