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)

1	This example illustrates remapping from one to two dimensional decomposition REAL, ARRAY(64,64) :: A REAL, ARRAY(64) :: B
2	!HPF$ PROCESSORS P(64)
3	!HPF$ PROCESSORS Q(8,8)
4	!HPF$ DYNAMIC :: A,B
5	*!HPF$ ALIGN B(:) WITH A(:,)**
6	*!HPF$ DISTRIBUTE A(,BLOCK)ONTO P ...**
7	*!HPF$ REALIGN B(:) WITH A(,:) ...**
8	!HPF$ REDISTRIBUTE A(CYCLIC,CYCLIC) ONTO Q ...
