Foil 63 Does HPF need a different type of compiler ?

From GCF Talk U - Lewis/NASA 3/9/92 Mardi Gras Conference on Concurrent Computing in Physical Sciences -- February 18, 1993. 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), .....) Traditionally arrange access to these elements in COMPILER
3 HPF: A=FUNC(B,C) Invoke ALREADY OPTIMIZED parallel implementation of FUNC In many cases, HPF compiler need not know anything about parallelization except interfaces, data layout etc.
