Collapsing Dimensions

If a dimension has a scalar index it is collapsed. Consider,

!HPF$ DISTRIBUTE (BLOCK,BLOCK) :: A, B
     ...
    CALL Xubbie(A(i,:),b(i,:))
     ...
    SUBROUTINE Xubbie(x,y)
     REAL, DIMENSION(:) :: x, y
     !HPF$ DISTRIBUTE (BLOCK) :: x, y

Will cause remapping. With 16 processors:

• actual arguments are distributed over 4 processors,
• on entry x and y will be redistributed over 16 processors,
• on exit x and y will be mapped in same way as actual argument,
