Prescriptive Distribution

Can prescribe alignment and distribution,

• may cause remapping,
• mapping is restored on procedure exit.

For example,

    SUBROUTINE Subby(A,B,RES)
     IMPLICIT NONE
     REAL, DIMENSION(:,:), INTENT(IN)  :: A, B
     REAL, DIMENSION(:,:), INTENT(OUT) :: RES
!HPF$ PROCESSORS, DIMENSION(2,2)       :: P
!HPF$ TEMPLATE, DIMENSION(4,6)         :: T
!HPF$ ALIGN (:,:) WITH T(:,:)          :: A, B, RES
!HPF$ DISTRIBUTE (BLOCK,BLOCK) ONTO P  :: T
       ...
    END SUBROUTINE Subby

Inside Subby the data will be mapped as specified.
