[Paraview] Paraview on SGI Altix 4000

[Biao She]

Hi Ken.
Which OpenGL verison does paraview need? Also, by saying OpenGL
drivers, do you mean the GLX version of the supercomputer? Coz my
paraview server is running on a linux machine. The version of GLX on
the machine is 1.2. The latest GLX version is 1.4. Do I need to update
the glx to 1.4? Thanks!
