Name:

    GetGlobalRNG - return global random number generator

Synopsis:

      GetGlobalRNG -> rngtype

Description:

      This function returns the global random number generator which
      can be used in situations where the same sequence of random
      numbers is needed in all MPI processes. The user must EXERT
      EXTREME CARE to ensure that all MPI processes use exactly
      the same random numbers while executing a script. NEST performs
      only a simple test upon each call to Simulate to check if the
      global RNGs on all MPI processes are still in sync.
