   Init_and_Exit.c 

   HOW TO COMPILE
   ----------

   shell$ mpicc -I<hmpi install directory>/include -o Init_and_Exit Init_and_Exit.c -L<hmpi install directory>/lib -lhmpi -lmpc

   Use 'mpirun' to run, the output would like below:

   My hostname is csserver, My processor name is csserver, My global rank is 0, global rank from mpi comm is 4, global size is 4
   My hostname is csserver, My processor name is csserver, My global rank is 1, global rank from mpi comm is 4, global size is 4
   My hostname is csserver, My processor name is csserver, My global rank is 2, global rank from mpi comm is 4, global size is 4
   My hostname is csserver, My processor name is csserver, My global rank is 3, global rank from mpi comm is 4, global size is 4
   ...
