NVIDIA cuSPARSELt is a high-performance CUDA library dedicated to general matrix-matrix operations in which at least one operand is a sparse matrix:
where \(op(A)/op(B)\) refers to in-place operations such as transpose/non-transpose, and \(alpha, beta\) are scalars or vectors.
The cuSPARSELt APIs allow flexibility in the algorithm/operation selection, epilogue, and matrix characteristics, including memory layout, alignment, and data types.
