There are no big changes in programming languages demanded by the new HP 
architecture (except that we need to compile code for several instruction 
sets).

The big change is in OS.

Interpreted scripts will probably not benefit at all from new processor 
architecture with many specialized core. For an interpreted language one 
need choose one type of core and use it exclusively.

In C it is needed a sophisticated code analysis to understand which part of 
the program to compile with which instruction sets, for every file it is 
need to be specified explicitly (or derived by a sophisticated code analysis 
tool). With Ada it is easier: The compiler just compiles all dependencies of 
a task to the right instruction set (as specified in the task's pragma).
