The ``Data Parallel'' Approach

This Slide is Shown as Demo

• List (in our example) is prescanned
  (possibly converted into a vector).
• Tasks for all its elements created at (essentially) the same time.
• Can be illustrated as follows:

  vproc([H1,H2,H3,H4,H5,H6,H7,H8,H9,H10],
       [HR1,HR2,HR3,HR4,HR5,HR6,HR7,HR8,HR9,HR10]) :-
          process_element(H1,HR1) &
          process_element(H2,HR2) &
          process_element(H3,HR3) &
          process_element(H4,HR4) &
          process_element(H5,HR5) &
          process_element(H6,HR6) &
          process_element(H7,HR7) &
          process_element(H8,HR8) &
          process_element(H9,HR9) &
          process_element(H10,HR10).

• Program only valid for a 10 element list!
