Perhaps an algorithm can be made faster, but often these multicore algorithms are also less efficient, and a less data-dependent way of putting my cores to good use would have been preferable. Potentially, other code could slow down due to cache trashing if too many parallel tasks run in parallel. Id rather be in charge of such matters myself; but I imagine adding a keyword arg for these matters would not be much trouble?
As I understand it, that is where the strength of Cilk+ lies. It does not force parallelisation, just suggests it. The decision to actually spawn parallel is decided at runtime depending on the load of the other cores. /David.
