It would have been easier to read the config file if you
had actually deleted the commented out device lines.
Additionally, the advice you seek depends on what you want
to do with the system. You forgot those details.
If you are running any floating point intensive applications
and these applications are multithreaded, you may want to use
the 4BSD scheduler rathar than ULE. The last time I tested
ULE with an MPI application, it display miserable performance
on a dual, quad-core opteron system.
