Data Mapping of Arrays (TU*X only)

On Tru64 UNIX systems, the HPF data mapping (or placement) directives can be used to describe alignment of arrays with respect to each other and their distribution across one or more processors.

These directives describe storage allocation for data without changing the meaning or results of the original program. The compiler uses the directives to schedule efficient parallel execution of the computation.

The following are data mapping directives:

A related directive is [NO]SEQUENCE, which lets you specify whether named (or all) data objects depend on array element order and storage association. For more information, see Sections and 15.3.7.
