itk::OpenCLDevice Class Reference

#include <itkOpenCLDevice.h>

Detailed Description

The OpenCLDevice class represents the collection of OpenCL devices to be used by the host.

The OpenCL framework allows applications to use a host and one or more OpenCL devices as a single heterogeneous parallel computer system. The GetDeviceType() can be used to query specific OpenCL devices or all OpenCL devices available. The valid values for GetDeviceType() are

\table \row \o Default \o The default OpenCL device in the system. The default device cannot be a {CL_DEVICE_TYPE_CUSTOM} device. \row \o CPU \o An OpenCL device that is the host processor. The host processor runs the OpenCL implementations and is a single or multi-core CPU. \row \o GPU \o An OpenCL device that is a GPU. By this we mean that the device can also be used to accelerate a 3D API such as OpenGL or DirectX. \row \o Accelerator \o Dedicated OpenCL accelerators (for example the IBM CELL Blade). These devices communicate with the host processor using a peripheral interconnect such as PCIe. \row \o Custom \o Dedicated accelerators that do not support programs written in OpenCL C. \row \o All \o All OpenCL devices available in the system except {CL_DEVICE_TYPE_CUSTOM} devices. \endtable

The GetDevices() function can be used to find all devices of a specific type, optionally constrained by the OpenCLPlatform they belong to.
