There is no additional + * requirement to include \em cl.h and to use either the C++ or original C + * bindings; it is enough to simply include \em cl.hpp. + * + * The bindings themselves are lightweight and correspond closely to the + * underlying C API. Using the C++ bindings introduces no additional execution + * overhead. + * + * There are numerous compatibility, portability and memory management + * fixes in the new header as well as additional OpenCL 2.0 features. + * As a result the header is not directly backward compatible and for this + * reason we release it as cl2.hpp rather than a new version of cl.hpp. + * + * + * \section compatibility Compatibility + * Due to the evolution of the underlying OpenCL API the 2.0 C++ bindings + * include an updated approach to defining supported feature versions + * and the range of valid underlying OpenCL runtime versions supported. + * + * The combination of preprocessor macros CL_HPP_TARGET_OPENCL_VERSION and + * CL_HPP_MINIMUM_OPENCL_VERSION control this range. These are three digit + * decimal values representing OpenCL runime versions. The default for + * the target is 200, representing OpenCL 2.0 and the minimum is also + * defined as 200. These settings would use 2.0 API calls only. + * If backward compatibility with a 1.2 runtime is required, the minimum + * version may be set to 120. + * + * Note that this is a compile-time setting, and so affects linking against + * a particular SDK version rather than the versioning of the loaded runtime. + * + * The earlier versions of the header included basic vector and string + * classes based loosely on STL versions. These were difficult to + * maintain and very rarely used. For the 2.0 header we now assume + * the presence of the standard library unless requested otherwise. + * We use std::array, std::vector, std::shared_ptr and std::string + * throughout to safely manage memory and reduce the chance of a + * recurrance of earlier memory management bugs. + * + * These classes are used through typedefs in the cl namespace: + * cl::array, cl::vector, cl::pointer and cl::string. + * In addition cl::allocate_pointer forwards to std::allocate_shared + * by default. + * In all cases these standard library classes can be replaced with + * custom interface-compatible versions using the CL_HPP_NO_STD_ARRAY, + * CL_HPP_NO_STD_VECTOR, CL_HPP_NO_STD_UNIQUE_PTR and + * CL_HPP_NO_STD_STRING macros. + * + * The OpenCL 1.x versions of the C++ bindings included a size_t wrapper + * class to interface with kernel enqueue. This caused unpleasant interactions + * with the standard size_t declaration and led to namespacing bugs. + * In the 2.0 version we have replaced this with a std::array-based interface. + * However, the old behaviour can be regained for backward compatibility + * using the CL_HPP_ENABLE_SIZE_T_COMPATIBILITY macro. + * + * Finally, the program construction interface used a clumsy vector-of-pairs + * design in the earlier versions. We have replaced that with a cleaner + * vector-of-vectors and vector-of-strings design. However, for backward + * compatibility old behaviour can be regained with the + * CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY macro. + * + * In OpenCL 2.0 OpenCL C is not entirely backward compatibility with + * earlier versions. As a result a flag must be passed to the OpenCL C + * compiled to request OpenCL 2.0 compilation of kernels with 1.2 as + * the default in the absence of the flag. + * In some cases the C++ bindings automatically compile code for ease. + * For those cases the compilation defaults to OpenCL C 2.0. + * If this is not wanted, the CL_HPP_CL_1_2_DEFAULT_BUILD macro may + * be specified to assume 1.2 compilation. + * If more fine-grained decisions on a per-kernel bases are required + * then explicit build operations that take the flag should be used. + * + * + * \section parameterization Parameters + * This header may be parameterized by a set of preprocessor macros. + * CL_HPP_TARGET_OPENCL_VERSION + * - Defines the target OpenCL runtime version to build the header against. + * Defaults to 200, representing OpenCL 2.0. + * CL_HPP_NO_STD_STRING + * - Do not use the standard library string class. + * cl::string is not defined and may be defined by the user before + * cl2.hpp is included. + * CL_HPP_NO_STD_VECTOR + * - Do not use the standard library vector class. + * cl::vector is not defined and may be defined by the user before + * cl2.hpp is included. + * CL_HPP_NO_STD_ARRAY + * - Do not use the standard library array class. + * cl::array is not defined and may be defined by the user before + * cl2.hpp is included. + * CL_HPP_NO_STD_UNIQUE_PTR + * - Do not use the standard library unique_ptr class. + * cl::pointer and the cl::allocate_pointer function are not defined + * and may be defined by the user before cl2.hpp is included. + * CL_HPP_ENABLE_DEVICE_FISSION + * - Enables device fission for OpenCL 1.2 platforms + * CL_HPP_ENABLE_EXCEPTIONS + * - Enable exceptions for use in the C++ bindings header. + * This is the preferred error handling mechanism but is not required. + * CL_HPP_ENABLE_SIZE_T_COMPATIBILITY + * - Backward compatibility option to support cl.hpp-style size_t class. + * Replaces the updated std::array derived version and removal of size_t + * from the namespace. Note that in this case the new size_t class + * is placed in the cl::compatibility namespace and thus requires + * an additional using declaration for direct backward compatibility. + * CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY + * - Enable older vector of pairs interface for construction of programs. + * CL_HPP_CL_1_2_DEFAULT_BUILD + * - Default to OpenCL C 1.2 compilation rather than OpenCL C 2.0 + * - applies to use of cl::Program construction and other program build variants. + * + * + * \section example Example + * + * The following example shows a general use case for the C++ + * bindings, including support for the optional exception feature and + * also the supplied vector and string classes, see following sections for + * decriptions of these features. + * + * \code + #define CL_HPP_ENABLE_EXCEPTIONS + #define CL_HPP_TARGET_OPENCL_VERSION 200 + + #include + #include + #include + #include + #include + + const int numElements = 32;
