For running the parallel programs you will need to install a copy of MPICH. 
This can be downloaded from http://www-unix.mcs.anl.gov/mpi/mpich/.

I am assuming that you have properly installed it, you have the utilities on
your path (including mpiCC and mpirun), and that you have properly
configured your cluster (have you created an /etc/mpich/machines.LINUX?).
In short: make sure that you can compile and run the examples of MPICH
before continuing.

To run the examples, just go into the corresponding directory and do

  make
  
An executable should be created in the bin directory. For the parallel
programs, just use mpirun to start the program on your cluster. It uses
the /etc/mpich/machines.LINUX file, or similar, and starts the specified
number of processes. Example:

  mpirun -np 10 nqueens

Enjoy!
