Member Function Documentation

createSubArrayView()

template<int N, typename T >

tBoolean MPI_View::createSubArrayView ( const std::array< int, N > &  arraySize, const std::array< int, N > &  startElement, const std::array< int, N > &  subarraySize  )

inline

create a sub array view of an array with N dimension

Template Parameters

N	: dimesnion of the space
T	: type of the element

Parameters

[in]	arraySize	size of the array ie number of elements per directions
[in]	startElement	: index of the start element within the array
[in]	subarraySize	size of the sub array ie the number of elements per directions

exemple createSubarrayView<2,tInteger>({4,4},{0,1},{2,2})

createVariableStepView()

template<typename T >

tBoolean MPI_View::createVariableStepView ( const tMPICount &  nElements, const std::valarray< tMPICount > &  elementSizes, const std::valarray< tMPICount > &  elementIndices  )

inline

create a variable step view

Template Parameters

T	: type of the element

Parameters

[in]	nElements	: number of elements of new type
[in]	elementSizes	: number of T elements within the i-th element of new type
[in]	elementIndices	number of T elements to reach the i-th elements of new type
[out]	newType	new type

Returns

an error code type --— : mask xx-x- : -holes

• nElements=2
• elementSizes={2,1} -elementIndices={0,3}

New()

static CORE_UniquePointer<MPI_View> MPI_View::New ( )

inlinestatic

create a new instance of class within an unique pointer

Returns

a new unique pointer of this class
