  Hi,

  I am working on MPI and I am sending a common task for computation to all the available workers. I am checking the time taken by each of them, since the workers computation speed is same i must be getting same time taken for computation by the workers. But the time taken by them is varying by huge marging. I am using MPI_Wtime for initializing the time. Can any one plz explain me why it (time) is getting varied.

  Thank You
