Parallel OpenGL rendering
From Gerris
Chromium looks like an interesting library to do this. See in particular the Writing a Parallel Application tutorial.
Because GfsView was written with a clear separation between the OpenGL rendering functions and shell/Gtk user interfaces, it should be relatively easy to do the generation of the OpenGL command stream in parallel and then to use Chromium to do "Sort-last (Z-compositing) rendering" on the single node containing the display and user interface.
