Patrick. To test of the parallel version is built and running/rendering correctly, try this: simply create a Sphere from the Sources menu (+Apply). Next create the "Process ID Scalars" filter from the Filters menu. You should see the sphere colored in 4 colors. If that works, all's well. Also, go the Settings dialog, on the Render View | Server Page, set the Remote Render Threshold to 0. That will ensure the use of parallel rendering, always.
The 100% CPU usage is expected. That's a OpenMPI thing. Refer to http://www.open-mpi.org/community/lists/users/2009/04/9017.php What type of datafile are you trying to load?
