Hi All,

Just FYI, I was reading the release notes for GCC 4.9 and saw that
support for Cilk Plus[1] was introduced. I haven't really followed
this before but found it interesting and thought it worth sharing.

Thanks!
steven

The site mentioned a branch for clang that has support. I didn't see
if it was available outside of the branch though.

Oh, I'm not suggesting we use this, but just be aware of it.  I'm
wouldn't be interested to actually use it for Csound unless it was
commonly available.

>From the FAQ[1]:

"By providing an abstraction for parallelism, Cilk Plus allows
developers to express their parallel algorithms in a way that is more
natural than many existing parallel libraries. Existing libraries for
writing parallel programs such as TBB and OpenMP require the developer
to restructure their application to break it into tasks that can be
run in parallel.  This restructuring can obscure the original
algorithm, making it harder for the programmer to reason about and
maintain the application.  Because the Intel Cilk Plus keywords have
serial semantics, developers can often express the parallelism
inherent in their algorithm by adding only a few keywords to the
original serial code.

Finally, Intel Cilk Plus allows you to write composable code.  That
is, you can write a library using Intel Cilk Plus and incorporate that
into other applications using Intel Cilk Plus without having to worry
about an explosion of threads.  Intel Cilk Plus uses a randomized
work-stealing scheduler to perform dynamic load-balancing which allows
the scheduler to efficiently handle nested parallelism in both
application and library without oversubscribing the machine with OS
threads."
