Foil 67 Compiler directives used in HPF

From HPCC Software Technologies Fall 96 -- Overview and HPF Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 26 September 96. by Geoffrey C. Fox
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
