2 HPF is designed so that parallelism is essentially explicit
3 This is embodied in 2 classes of operations:
  • INTRINSICS - 74 library routines
    • these would be coded in most efficient fashion possible for target machine - whether global address or message passing, eg., ALL, ANY, CSHIFT, SUM, ...
    • represent a set of primitives higher level than message passing which implement functionality needed in most (any) parallel processing systems
  • PARALLEL STATEMENTS - FORALL / array assignments, INDEPENDENT
    • here compile time analysis leads to efficient parallel implementation
    • HPF will again invoke a set of runtime library routines
    • need most efficient, not most convenient routines
