Is Cilk's approach to shared memory parallel to panacea programming?

Question

What problems in parallel programming with shared memory (in particular, multicore) cannot be solved or cannot be effectively solved using a solution like Cilk (i.e. nested parallelism data with kernel theft tasks)

Answer 1

I think the Cilk model is a nested parallelism task (which you can use parallelism data to implement). It's pretty sweet, but ...

Cilk does not support SIMD parallelism or parallelism streaming data.
