I suspect not. :) I still mean within the compiler, just at a higher
level program abstraction; a higher-level IR.
Concurrent languages can help, but history shows that it's tough to
get them accepted. HPF is a four-letter word here. ;) Now CAF,
on the other hand...
Maybe this trend will change with the new silicon constraints, but I'm
skeptical. We'll be programming in C, C++ and Fortran for a long time.
The compiler is going to have to find parallelism and the user is
going to have to help with directives.
