/*! \mainpage
* \section intro Introduction
* For many large applications C++ is the language of choice and so it seems
* reasonable to define C++ bindings for OpenCL.
*
* The interface is contained with a single C++ header file \em cl2.hpp and all
* definitions are contained within the namespace \em cl. 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_SHARED_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_SHARED_PTR
* - Do not use the standard library shared_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.
