HPF

• HPF is based on exploitation of loop parallellism.

• Iterations of the loop body that are conceptually independent can be executed concurrently.

• For example,

  ForAll (I = 1:N, J = 1:M)
  
  A(I,J) = I * B(J)
  End ForAll

• Data-mapping directives: Align, Distribute.

  !HPF$ Distribute D2 (Block, Block)
  
  !HPF$ Align A(I,J) with B(I+2, J+2)
