Foil 8 Compiler directives used in HPF

From HPFtutorial CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox(Tomasz 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
