Foil 93 Passing Distributed Arrays as Subprogram Arguments in HPF

From HPCC Software Technologies Fall 96 -- Overview and HPF Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 26 September 96. by Geoffrey C. Fox
There are three typical cases:
Subroutine requires data to use a particular mapping determined by subroutine
  • Arguments must be remapped
Subroutine can use any mapping so actual argument should be passed and used with current mapping
  • Here we have two cases depending on whether programmer knows or not (and tells subroutine) what incoming distribution is
Sometimes we need to remap due to array sections being passed
Any remappings must be undone on return from subroutine
