Foil 3 HPF is an extension of Fortran 90

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
1 To express data parallelism and so hide machine dependent features of parallel programming from the user
2 We use Fortran90 as base language both because it is
  • more advanced than Fortran 77 with object oriented features and
  • The array syntax allows an elegant explictly parallel expression of some operations
3 Use of Fortran90 is a Problem because
  • It is a complex language which it is difficult to build compilers for
  • Not many people use Fortran90 and maybe they will all switch to Java before Fortran90 gets in common practice
  • So perhaps it is "too little too late" and we should focus on supporting the past (Fortran77) and the "correct" future ( (HP)Java) and not an irrelevant middle solution .....
