         neutron transportation simulation code.  It is adapted from a
         similar miniapp provided by Andrew Siegel, whose algorithm is
         described in [1], where only one process in a compute node
         is used, and the compute nodes are divided into memory nodes
         and tracking nodes.    Memory nodes do not participate in particle
         tracking. Obviously, there is a lot of resource waste in this design.
