There are a least two parallelising C compilers for
the PC: Intel's and CodePlay's.  CodePlay say they do
a better job than Intel.  I imagine Intel hold a
differing opinion.

I'm interested in knowing the deficiencies of these
compilers.  I imagine they run into problems with
dependency analysis on complicated array expressions. 
Similarly, I'm interested in knowing in what areas HPF
and SAC are performant.  It appears to me that a
functional language (where dependency analysis is
simple) with array shape inference should be capable
of creating very array fast code is almost all
situations (and the SAC benchmarks show them beating
HPF).

Cheers,
Noel
