C compiler and multi-core support

[Martinfnp]

Hello all, I'm completely new in theory of C compiler and it's support
for multi-core hardware. Does anybody know whether compiler for
multi-core and SMP/AMP/BMP does need some special internal features?
I'm not talking right know about libs, just translation of the C code
into the instructions. I still understand that the most responsibility
is on the OS side and application even doesn't need to be recompiled.
Just special libs for SMP/BMP/AMP need to be linked? Is that correct or
am I wrong? How is it in the case there is no OS running, just basic
firmware? Martin

I think you only need a SMP-enabled kernel.
As I don't know much about that stuff, I may be wrong though.

I've found OpenMP which is probably coming as an standard. Today Intel
has it implemented in their compilers. You simply write app once and
then you decide whether it should be compiled for multi-core and up to
which level of the parallelism. It's really looking cool. Does anybody
know if somebody else is working to implement OpenMP into their
compilers? I just don't want follow dead thread. www.openmp.org

Sun compilers support OpenMP.

This is completely offtopic here since the topic is the C Language.
You would need to ask in groups specialising in whatever compiler
and/or OS you want to think about.
