Detailed Description

template<class value_type, class size_type>
struct cuv::allocator< value_type, size_type, host_memory_space >

specialization of template allocator for host_memory_space

The gcc compiler can deal directly with this, so we do not need to hide the implementation in a .cu file.

Member Function Documentation

template<class value_type , class size_type >

void cuv::allocator< value_type, size_type, host_memory_space >::alloc	(	value_type **	ptr,
		size_type	size
	)		const

Allocate memory for host matrices.

Parameters

ptr	Address of pointer which will be set to allocated memory
size	Size of array which should be allocated

This is the instance of the alloc function that is called by host vectors.

template<class value_type , class size_type >

void cuv::allocator< value_type, size_type, host_memory_space >::alloc ( const value_type **  ptr, size_type  size  ) const

inline

Allocate memory for host matrices - const allocator should never be called!

Parameters

ptr	Address of pointer which will be set to allocated memory
size	Size of array which should be allocated

This is the instance of the alloc function that is called by const host vectors.

Definition at line 139 of file accessors.hpp.

template<class value_type , class size_type >

void cuv::allocator< value_type, size_type, host_memory_space >::alloc2d	(	value_type **	ptr,
		size_type &	pitch,
		size_type	height,
		size_type	width
	)		const

Allocate 2D memory.

Parameters

ptr	Address of pointer which will be set to allocated memory
pitch	OUT size of one "line" in memory in bytes
height	number of lines in memory
width	number elements in one line

template<class value_type , class size_type >

void cuv::allocator< value_type, size_type, host_memory_space >::dealloc

(

value_type **

ptr

)

const

allocate memory

Deallocate memory for host matrices

Parameters

ptr	Address of pointer that will be freed

This is the instance of the dealloc function that is called by host vectors.

template<class value_type , class size_type >

void cuv::allocator< value_type, size_type, host_memory_space >::dealloc ( const value_type **  ptr ) const

inline

Deallocate memory for host matrices- const allocator should never be called!

Parameters

ptr	Address of pointer that will be freed

This is the instance of the dealloc function that is called by host vectors.
