non collective mpi_allreduce

[Mehdi Bostandoost]

Hi
  I am working on optimizing my code. one of the functions that I used in my code is MPI_ALLREDUCE. I want to have overlap between this communcation and my computation part of my code. is there any way to work around it?
  (it would be great to have sth like MPI_IALLREDUCE,MPI_WAIT)
