 As described in the chapter about the :doc:`Abstraction </basic/abstraction>`, the general design of the library is very similar to *CUDA* and *OpenCL* but extends both by some points, while not requiring any language extensions.
 General interface design as well as interface implementation decisions differentiating *alpaka* from those libraries are described in the Rationale section.
 It uses C++ because it is one of the most performant languages available on nearly all systems.

 The *alpaka* library extensively makes use of advanced functional C++ template meta-programming techniques.
 The Implementation Details section discusses the C++ library and the way it provides extensibility and optimizability.

 Those libraries often exploit the preprocessor and require non-trivial changes to the function declaration syntax.
 Therefore the *alpaka* library does not currently make use of *Boost.ConceptCheck*.
 Neither does it facilitate the proposed concept specification due to its dependency on non-standard compilers.
