Data Mapping

HPF data alignment and distribution directives allow the programmer to advise the compiler how to assign array elements to processor memories. This section discusses the basic data mapping features applicable, particularly those that are meaningful within a single scoping unit. Section 4 discusses features that apply when mapped variables appear as procedure arguments.
