'''Cilk''', '''Cilk++''', '''Cilk Plus''' and '''OpenCilk''' are [[general-purpose programming language|general-purpose]] [[programming language]]s designed for [[thread (computer science)|multithreaded]] [[parallel computing]]. They are based on the [[C (programming language)|C]] and [[C++]] programming languages, which they extend with constructs to express parallel loops and the [[fork–join model|fork–join idiom]].

Originally developed in the 1990s at the [[Massachusetts Institute of Technology]] (MIT) in the group of [[Charles E. Leiserson]], Cilk was later commercialized as Cilk++ by a spinoff company, Cilk Arts. That company was subsequently acquired by [[Intel]], which increased compatibility with existing C and C++ code, calling the result Cilk Plus. After Intel stopped supporting Cilk Plus in 2017, MIT is again developing  Cilk in the form of OpenCilk.
