= MPI-Povray Performance Report =
After running all of these povray cases under the path : /home/rider/scenes (default:/opt/povray31/scenes) , i have choose 5 (*.pov)files which are the highest cpu consumption(最耗運算資源-光影相關運算)for mpi-povray to run performance test.[[BR]]
All of the rendered files had been put in the /home/rider/povray_demo directory.[[BR]]

Rendered files for the performance experiment are listed below...

/home/rider/scenes/advanced/woodbox.pov [[BR]]
/home/rider/objects/pawns.pov [[BR]]
/home/rider/scenes/advanced/whiltile.pov [[BR]]
/home/rider/scenes/interior/ballbox.pov [[BR]]
