Data Mapping Features

Data mapping features provided are those that have been found useful most often. When data is explicitly mapped, only one copy of the data storage is created unless the explicit mapping directs otherwise. The value of explicitly mapped replicated data items must be consistent between processors as is the case in HPF. Storage and sequence association for explicitly mapped arrays is not guaranteed in HPF_CRAFT. For private data, storage and sequence association follows the Fortran 90 rules.

A new directive is included for completeness: PE_PRIVATE, which specifies that the data should conform to the default behavior. The values of private varaibles may vary on different processors.
