   Description of the test
   ========================

   Returns the time of execution of broadcast from a root 
   process to the rest of the processes.
   The test uses the function HMPI_Timeof.

   bcast.mpc ---->         Performance model definition for the broadcast algorithm
   HMPI_bcast.c ---->      main containing the HMPI_Timeof to return the estimated time
                           of execution of the performance model describing the performance
                           model.

   HOW TO RUN
   ----------
   shell$ mpcc bcast.mpc

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

   Use 'mpirun' to run the program, the output should look like the following:

   Total number of processes participating in broadcast = 4
   Number of bytes broadcast = 8000000, time in seconds=0.130
