Hi,
 

  I have tried the attached program which counts the no. of prime numbers with Starpu-MPI. I'm not getting result. I'm not understanding where is the problem. Can anyone help me.

You need to wait for all your StarPU tasks to be terminated to call MPI_Reduce, in other words, you are missing a call to starpu_task_wait_for_all() before calling MPI_Reduce.
