Methods in org.apache.sysds.runtime.instructions.gpu.context that return CSRPointer

Modifier and Type	Method	Description
static CSRPointer	CSRPointer.allocateEmpty(GPUContext gCtx, long nnz2, long rows)
static CSRPointer	CSRPointer.allocateEmpty(GPUContext gCtx, long nnz2, long rows, boolean initialize)	Factory method to allocate an empty CSR Sparse matrix on the GPU
static CSRPointer	CSRPointer.allocateForDgeam(GPUContext gCtx, jcuda.jcusparse.cusparseHandle handle, CSRPointer A, CSRPointer B, int m, int n)	Estimates the number of non zero elements from the results of a sparse cusparseDgeam operation C = a op(A) + b op(B)
static CSRPointer	CSRPointer.allocateForMatrixMultiply(GPUContext gCtx, jcuda.jcusparse.cusparseHandle handle, CSRPointer A, int transA, CSRPointer B, int transB, int m, int n, int k, int dataType)	Estimates the number of non-zero elements from the result of a sparse matrix multiplication C = A * B and returns the CSRPointer to C with the appropriate GPU memory.
CSRPointer	CSRPointer.clone(int rows)
static CSRPointer	GPUObject.columnMajorDenseToRowMajorSparse(GPUContext gCtx, jcuda.jcusparse.cusparseHandle cusparseHandle, jcuda.Pointer densePtr, int rows, int cols)	Convenience method to convert a CSR matrix to a dense matrix on the GPU Since the allocated matrix is temporary, bookkeeping is not updated.
CSRPointer	GPUObject.getJcudaSparseMatrixPtr()	Pointer to sparse matrix
CSRPointer	GPUObject.getSparseMatrixCudaPointer()	Convenience method to directly examine the Sparse matrix on GPU
static CSRPointer	CSRPointer.transposeCSR(GPUContext gCtx, jcuda.jcusparse.cusparseHandle handle, CSRPointer src, int srcRows, int srcCols, int dataType)	Physically transpose a CSR matrix (srcRows × srcCols ➜ srcCols × srcRows).
