Foil 19 Parallelism 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
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
Compiler may choose not to exploit information about parallelism
Compiler may detect parallelism in sequential code
