Local Routines Written in Fortran 90

The suggested interface to local SPMD routines written in Fortran 90 is the same as that for HPF local routines, with these few exceptions:

• Only Fortran 90 constructs should be used; it may not be possible to use extensions peculiar to HPF such as FORALL and the HPF library routines.
• It is recommended that Fortran 90 language processors to be used for this purpose be extended to support the HPF local distribution query routines GLOBAL_ALIGNMENT, GLOBAL_TEMPLATE, and GLOBAL_DISTRIBUTION and the PROCID derived type as described in Section . It is also recommended that these facilities be defined in a Fortran 90 module named HPF_LOCAL_LIBRARY.
• Assuming that the intent is to compile such routines with a non-HPF Fortran 90 compiler, the Fortran 90 program text should be in separate files rather than incorporated into HPF source code.
• The suggested extrinsic kind keyword for this calling interface is F90_LOCAL.

The restrictions listed in Section ought to apply as well to local routines written in Fortran 90.
