Foil 23 Compiler directives used in HPF

From New CPS615HPF and Fortran90 Discussion Sept 17 96 Basic Simulation Track for Computational Science CPS615 -- Fall Semester 96. by Geoffrey C. Fox, Tom Haupt
The directives are structured comments that suggest implementation strategies or assert facts about a program to the compiler
They may affect the efficiency of the computation performed, but do not change the value computed by the program
As in Fortran 90 statements, there are both:
  • declarative directives
  • executable directives
