Member Data Documentation

CUDPPSegmentedScanPlan* CUDPPSparseMatrixVectorMultiplyPlan::m_segmentedScanPlan

Performs a segmented scan of type T using this plan

void* CUDPPSparseMatrixVectorMultiplyPlan::m_d_prod

Vector of products (of an element in A and its corresponding (thats is belongs to the same row) element in x; this is the input and output of segmented scan

unsigned int* CUDPPSparseMatrixVectorMultiplyPlan::m_d_flags

Vector of flags where a flag is set if an element of A is the first element of its row; this is the flags vector for segmented scan

unsigned int* CUDPPSparseMatrixVectorMultiplyPlan::m_d_rowFinalIndex

Vector of row end indices, which for each row specifies an index in A which is the last element of that row. Resides in GPU memory.

unsigned int* CUDPPSparseMatrixVectorMultiplyPlan::m_d_rowIndex

Vector of row end indices, which for each row specifies an index in A which is the first element of that row. Resides in GPU memory.

unsigned int* CUDPPSparseMatrixVectorMultiplyPlan::m_d_index

Vector of column numbers one for each element in A

void* CUDPPSparseMatrixVectorMultiplyPlan::m_d_A

The A matrix

unsigned int* CUDPPSparseMatrixVectorMultiplyPlan::m_rowFinalIndex

Vector of row end indices, which for each row specifies an index in A which is the last element of that row. Resides in CPU memory.
