Foil 25 High Performance Fortran HPF2 Changes

From CPS615-End of Numerical Integration and Very End of HPF Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 24 October 96. by Geoffrey C. Fox *
Secs 123.8
1 The original HPF 1.0 omitted some key capabilities which were known to be important but syntax and functionality was unclear in 1993
  • Further experience has shown that HPF compilers have proven to be difficult to write!
2 The HPF Forum met in 1995-96 and has approved a set of Extensions and Simplifications of HPF
3 The concept of a base HPF 2.0 and Approved Extensions has been agreed
4 Note approved extensions (which presumably vendors need not implement) include critical capability for dynamic irregular problems
5 DYNAMIC REALIGN and REDISTRIBUTE are no longer in base language and are just "appproved extensions"
6 Suprisingly no parallel I/O capabilities were approved!
