Detailed Description

template<typename T>
class PSkel::MaskBase< T >

MaskBase is the basic class that implements the mask data structure used by the stencil skeleton in order to select the neighborhood for each element of a given input array.

Constructor & Destructor Documentation

template<typename T >

PSkel::MaskBase< T >::MaskBase	(	size_t	size = 0,
		size_t	dimension = 0,
		T	haloVal = T(0),
		size_t	range = 0
	)		[protected]

The MaskBase constructor creates and allocates the specified mask in the host memory.

Parameters:

[in]	size	the size of the mask.
[in]	dimension	the dimension of the mask.
[in]	haloVal	the value used when the array is accessed out of bounds.
[in]	range	the range of the mask; if range is 0, it is calculated as the maximum absolute value on the mask.

Member Function Documentation

template<typename T >

void PSkel::MaskBase< T >::deviceAlloc

(

)

Allocates the mask in device memory, including both the indexes and the weights.

template<typename T >

void PSkel::MaskBase< T >::deviceFree

(

)

Frees the allocated device memory.

template<typename T >

T PSkel::MaskBase< T >::getWeight

(

size_t

n

)

Get the weight of a given element in the mask.

Parameters:

[in]

n

index of the element in the mask.

Returns:

the weight of the specified element.

template<typename T >

void PSkel::MaskBase< T >::hostAlloc

(

)

Allocates the mask in host (main) memory, including both the indexes and the weights.

template<typename T >

void PSkel::MaskBase< T >::hostFree

(

)

Frees the allocated host (main) memory.

template<typename T >

size_t PSkel::MaskBase< T >::memSize

(

)

const

Get the size, in bytes, of the allocated memory for storing the mask.

Returns:

the total of bytes allocated in memory for storing the mask.
