Detailed Description

Structure to encapsulate sparse matrix data encoded in COO form to clSPARSE API.

Note

The indices stored are 0-based

It is the users responsibility to allocate/deallocate OpenCL buffers

Member Data Documentation

void* clsparseCooMatrix::col_indices

column index for corresponding element; array size num_nonzeros

cl_mem clsparseCooMatrix::col_indices

column index for corresponding element; array size num_nonzeros

clsparseIdx_t clsparseCooMatrix::num_cols

Number of columns this matrix has if viewed as dense

clsparseIdx_t clsparseCooMatrix::num_nonzeros

Number of values in matrix that are non-zero

clsparseIdx_t clsparseCooMatrix::num_rows

Number of rows this matrix has if viewed as dense

clsparseIdx_t clsparseCooMatrix::off_col_indices

Given that cl_mem objects are opaque without pointer arithmetic, these offsets are added to the cl_mem locations on device to define beginning of the data in the cl_mem buffers

clsparseIdx_t clsparseCooMatrix::off_row_indices

Given that cl_mem objects are opaque without pointer arithmetic, these offsets are added to the cl_mem locations on device to define beginning of the data in the cl_mem buffers

clsparseIdx_t clsparseCooMatrix::off_values

Given that cl_mem objects are opaque without pointer arithmetic, these offsets are added to the cl_mem locations on device to define beginning of the data in the cl_mem buffers

void* clsparseCooMatrix::row_indices

row index for corresponding element; array size num_nonzeros

cl_mem clsparseCooMatrix::row_indices

row index for corresponding element; array size num_nonzeros

void* clsparseCooMatrix::values

CSR non-zero values of size num_nonzeros

cl_mem clsparseCooMatrix::values

CSR non-zero values of size num_nonzeros
