That's because it's not part of the language specification. :o)

TheCilk RuntimeAPI is documented in the include files in the cilk directory. The information is in Doxygen format, which is pretty readable. See cilk/ReadMe.html for information for how to downloadDoxygen and use it to generate HTML pages (or other formats).

Anyway, the functions you're looking for are __cilkrts_get_worker_number() and __cilkrts_get_nworkers(). They're declared in cilk/cilk_api.h.

Warning:If you're using __cilkrts_get_worker_number() for anything that's not justcosmetic, you probably want to use a reducer instead.
