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
1 Parallelism in HPF is expressed explicitly
  • Fortran 90 array expressions and assignments (including WHERE)
  • HPF Library and Array intrinsics
  • FORALL statement and construct
    • PURE labels procedures that can be used in FORALL as they have no "side-effects"
  • INDEPENDENT assertion on DO loops
2 Compiler may choose not to exploit information about parallelism
3 Compiler may detect parallelism in sequential code
