Foil 25 Advanced Mapping Directives -- ReDistribution and ReAlign

From HPFtutorial CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox(Tomasz Haupt)

This example illustrates remapping from one to two dimensional decomposition

!HPF$ PROCESSORS P(64)

!HPF$ PROCESSORS Q(8,8)

!HPF$ DYNAMIC :: A,B

!HPF$ ALIGN B(:) WITH A(:,*)

!HPF$ DISTRIBUTE A(*,BLOCK)ONTO P

!HPF$ REALIGN B(:) WITH A(*,:)

!HPF$ REDISTRIBUTE A(CYCLIC,CYCLIC) ONTO Q
