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.
