|
|
* \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 cl2.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 functions 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.
