ISPC's foreach explicitly declares that each loop as independent where each loops can be executed as parallel instances in groups known as gangs; Cilk has similar semantics where each call to cilk_spawn implies that the invoked function can be executed independently (asynchronously) of the main thread and any other call to cilk_spawn as concurrent instances. However when it come to implementation ISPC differs from Cilk in that ISPC is has it's gangs of program instannces mapped to SIMD instrucitons on a single core; that define a set of tasks that can be executed concurrently, while cilk implements a fork join pattern where each instances can be executed as a thread in any core
