Extrinsic Procedures

This chapter defines the mechanism by which HPF programs may call non-HPF subprograms as extrinsic procedures. It provides the information needed to write an explicit interface for a non-HPF procedure. It defines the means for handling distributed and replicated data at the interface. This allows the programmer to use non-Fortran language facilities, perhaps to descend to a lower level of abstraction to handle problems that are not efficiently addressed by HPF, to hand-tune critical kernels, or to call optimized libraries. This interface can also be used to interface HPF to other languages, such as C.
