Foil 51 What type of compiler is 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
1 HPF makes much greater use of runtime optimizations than the traditional sequential or parallel compiler
2 Fortran 77: Do 1 I=1,N 1 A(I) = FUNC(B(I), B(I +/- 1), C(I), C(I +/- 1), .....)
3 Traditionally arrange access to these elements in COMPILER
4 HPF: A=FUNC(B,C)
5 Invoke ALREADY OPTIMIZED parallel implementation of FUNC In many cases, HPF compiler need not know anything about parallelization except interfaces, data layout etc.
