We are only using threads for experimental development of the  
nonbonded interaction loop. The multi-level-cache-locality features  
on modern CPUs (even NUMA on Opterons) means that you normally get  
better performance by partitioning the problem into separate MPI  
processes, where each process resides on a separate core.
