How does the CAVELib config file differ from the .mpconfig file?
The CAVELib config file is similar to the .mpconfig file in that it specifies the windows and viewports to be rendered on each PC in the cluster. The file is named HOST.config where HOST is the capitalized name of the PC (Win32). On Linux, the file should also be named HOST.config but HOST is the complete name returned by the hostname command. It should be placed in the %CAVE_HOME%\etc\ directory (on win32) or the $CAVE_HOME/etc/ directory (on Linux.) It is also used to specify tracker and controller options (replacing many environment variables on SGI platforms.) It also specifies cluster distribution details such as which PC is the master node and how many nodes there are in total in the cluster.
