Detailed Description

A class representing an OpenCL device.

This class represents one OpenCL device which can be used to execute the skeletons on if OpenCL is used as backend. Stores various properties about the device and provides functions that return them. As actual OpenCL devices are managed by StarPU in this translation, so this class merely acts as a wrapper, encapsulating the properties obtained by StarPU. Also contains a OpenCL context and queue.

Constructor & Destructor Documentation

skepu::Device_CL::Device_CL ( cl_device_id  id, cl_device_type  type, cl_context  context  )

inline

The constructor creates a device from an ID, device type (should be GPU in this version) and a context. It gets all the properties and creates a command-queue.

Parameters

id	Device ID for the device that is to be created.
type	The OpenCL device type.
context	A valid OpenCL context.

Here is the call graph for this function:

skepu::Device_CL::~Device_CL ( )

inline

The destructor releases the OpenCL queue and context.
