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!

The HPF Forum met in 1995-96 and has approved a set of Extensions and Simplifications of HPF
|
|
The concept of a base HPF 2.0 and Approved Extensions has been agreed
|
|
Note approved extensions (which presumably vendors need not implement) include critical capability for dynamic irregular problems
|
|
DYNAMIC REALIGN and REDISTRIBUTE are no longer in base language and are just "appproved extensions"
|
|
Suprisingly no parallel I/O capabilities were approved!
