Foil 3 Important Features of Fortran90

From CPS615-Introduction to F90 Features, Rationale for HPF and Problem Architecture Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 24 September 96. by Geoffrey C. Fox *
Secs 21.6
Arrays are very well supported with memory allocation and set of intrinsics, better passing to procedures etc.
  • This is key capability for HPF
Derived Types allow general object structure (without inheritance) in F90
  • Pointers
  • This area NOT well supported by HPF Compilers as of Summer 1996
Modules replace COMMON INCLUDE etc.
Procedures (functions,subroutines) allow better interfaces, recursion, optional parameters etc.
Better Syntax with free form, more loop control etc.
