Detailed Description

template<typename T>
class skepu::DeviceMemPointer_Matrix_CL< T >

A class representing an OpenCL device memory allocation for Matrix.

This class represents an OpenCL device memory allocation and controls the data transfers between host and device. Used rarely in this translation as data management is mostly done by StarPU.

Constructor & Destructor Documentation

template<typename T >

skepu::DeviceMemPointer_Matrix_CL< T >::DeviceMemPointer_Matrix_CL	(	T *	start,
		int	rows,
		int	cols,
		Device_CL *	device
	)

The constructor allocates a certain amount of space in device memory and stores a pointer to some data in host memory.

Parameters

start	Pointer to data in host memory.
rows	Number of rows.
cols	Number of columns.
device	Pointer to a valid device to allocate the space on.

References skepu::Device_CL::getContext().

Here is the call graph for this function:

template<typename T >

skepu::DeviceMemPointer_Matrix_CL< T >::~DeviceMemPointer_Matrix_CL

(

)

The destructor releases the allocated device memory.

Member Function Documentation

template<typename T >

void skepu::DeviceMemPointer_Matrix_CL< T >::changeDeviceData

(

)

Marks the device data as changed.

template<typename T >

void skepu::DeviceMemPointer_Matrix_CL< T >::copyDeviceToHost	(	int	rows = -1,
		int	cols = -1
	)		const

Copies data from device memory to host memory. Only copies if data on device has been marked as changed.

Parameters

rows	Number of rows.
cols	Number of columns.

template<typename T >

void skepu::DeviceMemPointer_Matrix_CL< T >::copyHostToDevice	(	int	rows = -1,
		int	cols = -1
	)		const

Copies data from host memory to device memory.

Parameters

rows	Number of rows.
cols	Number of columns.

template<typename T >

cl_mem skepu::DeviceMemPointer_Matrix_CL< T >::getDeviceDataPointer

(

)

const

Returns

OpenCL memory object representing data on the device.
