Visualisation of `*` Distribution

A * instead of a distribution method means: ``do not distribute this dimension''.

    PROGRAM Skwiffy
     IMPLICIT NONE
     REAL, DIMENSION(4,4)         :: A, B, C
!HPF$ PROCESSORS, DIMENSION(4)    :: Q
!HPF$ DISTRIBUTE (*,BLOCK) ONTO Q :: A, B, C
      B = 1; C = 1; A = B + C; PRINT*, A
    END PROGRAM Skwiffy
