_Cilk_spawn is the correct keyword. "cilk_spawn" can be used if the user includes <cilk/cilk.h> which has the following 3 lines (and that's the whole file) #define cilk_spawn _Cilk_spawn #define cilk_sync _Cilk_sync #define cilk_for _Cilk_for In Cilk there are basically 3 keywords: _Cilk_spawn, _Cilk_sync and _Cilk_for. _Cilk_for patch is still under review but _Cilk_spawn and _Cilk_sync keywords are supported. > > -Andi
