hpx::future<hpx::serialization::serialize_buffer<char> > hpx::cuda::buffer::enqueue_read	(	size_t	offset,
		size_t	size
	)		[inline]

Method copy the data on the attached device to the host.

Parameters:

offset	Offset, where to start copying data
size	Size of the data on the device

Returns:

A future with the serialized data

Note:

This method is for accessing data on remote localities.

hpx::future<uintptr_t> hpx::cuda::buffer::enqueue_read_local	(	size_t	offset,
		size_t	size
	)		[inline]

Method copy the data on the attached device to the host.

Parameters:

offset	Offset, where to start copying data
size	Size of the data on the device

Returns:

A future with the uintptr_t to the data

Note:

This method is for accessing data on local localities.

template<typename T >

T* hpx::cuda::buffer::enqueue_read_sync	(	size_t	offset,
		size_t	size
	)		[inline]

Method copy synchronized the data on the attached device to the host.

Parameters:

offset	Offset, where to start copying data
size	Size of the data on the device

Returns:

Pointer to the data on the host

Examples:

build_kernel.cpp, and build_kernel_from_file.cpp.

hpx::future<void> hpx::cuda::buffer::enqueue_write	(	size_t	offset,
		size_t	size,
		const void *	data
	)		const [inline]

Method copies the provided data on the attached device memory.

Parameters:

offset	Offset, where to start copying data
size	Size of the data on the device
data	Pointer to the data, which is transfered to the device

Examples:

build_kernel.cpp, and build_kernel_from_file.cpp.

hpx::lcos::future<void> hpx::cuda::buffer::set_size

(

size_t

size

)

[inline]

Method sets the buffer's size.

Parameters:

size	The size of the buffer

Note:

Use this methods carefully for extending a buffer. Adaptive buffer on GPU are mostly performing bad.

hpx::lcos::future<size_t> hpx::cuda::buffer::size

(

)

[inline]

Method returns the buffer's size.

Returns:

The buffer size
